The Tudor ‘MN’ Military Submariner

The relationship between Tudor and the French Navy, or Marine Nationale, is one of the most storied partnerships in military horology. Beginning in 1956, Tudor supplied watches for field testing to Groupe d’Étude et de Recherches Sous-Marines (G.E.R.S.), a research and development arm of the Marine Nationale focused on underwater exploration and combat diving. The first model references, 7922 and 7923, underwent rigorous trials before receiving approval by the French Navy. This endorsement marked the beginning of an official supplier relationship in 1961, a collaboration that would continue into the early 1980s and then be reignited in 2021.

Tudor’s Marine Nationale Submariners were exclusively issued to navy divers, commandos, and special forces operators, serving as essential tools in underwater missions. Over the years, Tudor refined its dive watch designs based on the feedback and revised requirements of the Marine Nationale, leading to some of the most iconic military-issued dive watches ever produced.

What makes a Tudor an MN?
For collectors and enthusiasts, true Marine Nationale-issued Tudor watches have an unmistakable identity shaped by their military provenance, specific references, and unique configurations that evolved over nearly three decades of service. Unlike Rolex Submariners issued to the UK forces which featured attributes unique to ‘issued’ watches, Tudor MN Submariners were indistinguishable from their civilian counterparts until 1974. Below is a summary of key references issued to the French Navy, along with the configurations that define each period.

References Issued to the Marine Nationale
7922 Small Crown (1956–1957)
7923 Small Crown (1956)
7922 Big Crown (1957–1958, prototype cases based on Rolex 6538)
7924 Big Crown (1958–1959)
7928 Crown Guard Submariner (1959–1968)
7016 Snowflake (1974–1975, black dial)
9401 Snowflake (1975–early 1980s, blue dial)
9401 Mercedes hands and Triangle Markers (early 1980s, blue dial)

Key Configurations by Era

1956 – Reference 7922 (First Batch, Small Crown)
The first Tudor Submariners delivered to the Marine Nationale in 1956 were designated as model reference 7922. These watches featured black gilt dials marked 100m, Mercedes hands, and a 6mm Rolex winding crown. This was the batch tested by G.E.R.S. before Tudor became an official supplier to the French Navy.

1956 – Reference 7923 (Manual Wind, Small Crown)
Delivered alongside reference 7922, the reference 7923 was also issued. These watches featured black gilt dials marked 100m, pencil hands, and a 6mm Rolex winding crown. The dials did not feature the word PRINCE, which signified that the watch had a manual wind movement, as Prince was Tudor’s equivalent of Rolex’s Perpetual.

1957 – Reference 7922 (Big Crown Prototype Cases)
In 1957, Tudor experimented with a new design in response to Marine Nationale feedback for a more robust case with an easier to operate winding crown, by repurposing Rolex Submariner 6538 cases. These watches were fitted with Tudor dials and movements, but retained their original Rolex serial numbers, with the 6538 reference re-engraved as 7922 between the lugs. The case backs had 6538 crossed out and 7922 punched above. These watches kept a 7922 100m dial but were capable of diving to a depth of 200m thanks to the Rolex case, Mercedes pattern hands, and an 8mm Rolex winding crown.

1958 – Reference 7924 (Big Crown)
Following the success of the reworked 7922, Tudor introduced the 7924 in 1958, the first Submariner officially rated to 200m. Fitted with gilt dials marked 200s and Mercedes hands and like the previous experimental batch, it featured an 8mm Rolex winding crown.

1959 – Reference 7928 (Crown Guard Case)
By 1959, Tudor introduced the 7928, marking a major design shift with the addition of crown guards. This model evolved through four variations of crown guards: Square, Eagle Beak, Pointed, and Rounded crown guards. Alongside these case modifications, the 7928 initially featured a gilt black 200m dial, Mercedes hands, and a 7mm Rolex winding crown. This model remained in production for over a decade and the dials transitioned to matte dials from glossy dials in the mid to late 1960s.

1974 – Reference 7016 (First Snowflake MN Watches)
The arrival of the 7016 in 1974 signalled a new era for Marine Nationale Tudors. This was the first reference to feature the now-iconic Snowflake hands, developed in direct response to requests for improved underwater legibility. The early 7016s were fitted with black dials and black bezel inserts, paired with square marker dials. These watches retained the 7mm Rolex winding crown. Crucially, this was also the first reference to feature the hallmark MN case back engravings, with issued examples engraved MN74. Watches from this batch generally fall within the 827xxx serial range.

1975 – Reference 9401 (Blue Snowflake MN Watches)
In 1975, Tudor introduced the reference 9401, which became the definitive Marine Nationale Tudor for many collectors. These watches featured blue dials with matching blue bezel inserts, Snowflake hands, and the same square marker dial layout as the earlier 7016. The 7mm Rolex winding crown remained unchanged. These watches were issued through the early 1980s and continued the MN case back engraving tradition.

Early 1980s – Reference 9401 (Blue Mercedes hands MN Watches)
By the early 1980s, the last generation of Marine Nationale Tudors transitioned to a new dial configuration. These late 9401s featured blue dials and bezel inserts but reverted to Mercedes pattern hands, paired with a triangle marker dial layout. The 7mm Rolex winding crown remained a consistent feature. These were among the last Tudors officially issued to the Marine Nationale before the relationship came to an end.

Key Features of MN-Issued Watches
Determining whether a Tudor Submariner was officially issued to the Marine Nationale can be challenging. Unlike many military-issued timepieces that came with standardised documentation, Marine Nationale Tudors were tools of the trade, utilitarian watches issued directly to Navy divers and commandos with little concern for future collectability.

One of the most important sources for verifying an MN-issued Tudor comes from a Rolex watchmaker based in Toulon, who meticulously recorded every Marine Nationale Tudor that passed through his workshop for servicing. However, it is crucial to note that these records only account for watches issued to the southern base in Toulon. There are no surviving records for watches issued in northern France, making verification for those examples much more difficult.

For models issued before 1974, the only definitive way to confirm an MN-issued watch is if it appears in the Toulon watchmaker’s ledgers. Watches from this period lack military engravings, meaning provenance and historical documentation are essential.

From 1974 to 1982, Marine Nationale Tudors featured distinct case back engravings, making them far easier to identify. These engravings followed a standardised format with the letters MN followed by the year of issue. The placement of the engraving varied slightly over the years:
1974 – MN 74 – Center of case back
1975 – MN 1975 – Center of case back (the only year with the full year engraved)
1976 – MN 76 – Center of case back
1977 – MN 77 – Center of case back
1978 – MN 78 – Bottom of case back
1979 to 1982 – MN 79, 80, 81, 82 – Center of case back

While these engravings provide strong evidence of Marine Nationale provenance, collectors should always be mindful of originality. Over the decades, some watches have had their engravings polished off or case backs swapped during service. As always with military watches, careful research and authentication remain key.

The Modern Evolution: The Pelagos FXD

In May 2021, Tudor reaffirmed its historical connection with the Marine Nationale, announcing an official partnership with the French Navy. While the brand had long celebrated its military heritage—most notably with the Black Bay Fifty-Eight—the launch of the Pelagos FXD marked a significant return to true military collaboration. Unlike previous releases that paid homage to the past, the FXD was designed specifically for modern Marine Nationale divers, tailored to the operational needs of Commando Hubert, the elite combat swimmer unit of the French Navy.

Whilst the FXD is very much a watch designed with the Marine Nationale, the actual watches delivered to the Commando Hubert divers differ from those sold by official Tudor retailers. The most obvious difference is the dial. Devoid of any mention of chronometer certification, the issued watches display a stripped-back aesthetic, featuring only PELAGOS and 200m—not even the imperial 600ft depth rating. This no-nonsense approach to the dial design reinforces the FXD’s role as a purpose-built military tool.

The case back is also significantly different. One of the most distinctive elements of the retail FXD is the engraved MN case back, a direct nod to the hallmark case back engravings found on vintage Marine Nationale Tudors from the 1970s and 1980s. These historical engravings consisted of MN followed by a short-form year, such as MN74 for 1974 or MN76 for 1976. (A small but interesting detail—only in 1975 did Tudor engrave the full year, marking watches as MN 1975.) The retail FXDs continue this tradition, with watches produced in 2021 engraved MN21, followed by MN22 in 2022, and so on. However, the actual issued watches used by Commando Hubert divers feature a much more stripped-back case back, engraved with only the year and a small issue number, reinforcing their utilitarian nature.

Finally, the reference number of the issued watches is ‘25797’ where the civilian reference is ‘25707’.

The FXD retains the core characteristics that made Marine Nationale Tudors iconic: a robust, functional design, lightweight materials, and fixed strap bars for added durability. With its 42mm titanium case, ultra-legible dial, and bi-directional countdown bezel—specifically designed for underwater navigation—it is a modern-day MilSub, not just a marketing exercise. It embodies Tudor’s historical relationship with the Marine Nationale while proving that the collaboration remains as functional today as it was in the 1950s.

For collectors and enthusiasts, Marine Nationale Tudors remain among the most desirable tool watches on the market. Whether it’s the patinated charm of an original “M.N.”-engraved 7016 or the cutting-edge engineering of the Pelagos FXD, these watches embody the perfect balance of heritage, functionality, and military precision.

The Rolex ‘Military’ Submariner

The Rolex Military Submariner

In 1972 the Rolex Submariner replaced the Omega Seamaster as the watch of choice for its the UK military by the Ministry of Defence (MOD). Military specification Rolex Submariners (often referred to as ‘Milsubs’ by collectors) were then delivered to the British Ministry of Defence (MOD) by the Rolex Watch Company and made available to both the UKSF Special Boat Service (SBS) and Special Air Service (SAS) divers.

The features of the Rolex military Submariner differed to the standard production Rolex Submariner sold by Rolex via their authorised retail outlets, as the military versions were modified to meet the needs of the MOD elite units specific requirements.

Approximately 1200 modified military specification Rolex Submariners were delivered by Rolex to the Royal Navy & British Army between 1972 and 1979.

Due to their use in challenging environments, the survival rate for Milsubs in their original configuration is low. Thus rarity along with their fascinating and important military provenance is the reason they have become so sought after by vintage and military watch collectors.

Rolex Military Submariner

The Model References

The original Rolex military Submariners were issued using 3 different references 5513, 5513/5517 (referred to as a double reference) and 5517. Each reference is engraved as follows:-

5513 (engraved between the lugs at 12:00)
5513/5517 (5513 engraved between the lugs at 12:00 and 5517 engraved under the 7:00 lug)
5517 (engraved between the lugs at 12:00)

NOTE: Whereas model reference. 5513 was a modified version of the existing standard production Rolex Submariner, model ref. 5517 was unique to the military Submariner. This particular model reference was never sold commercially, and thus has become the most sought after of the 3 references by collectors.

Fixed bars

Full Specification

Each reference of the Rolex military Submariner has the same modified specification:

  • A 600 ft = 200m matt dial with circled T – denoting the use of Tritium within the luminous compound
  • Sword or gladiator Hands – for greater visibility
  • A continually graduated 60 minute bezel – for more accurate measurement of time underwater
  • Anti reflective satin case finish
  • Military fixed bars – for enhanced durability, to be used in conjunction with an admiralty strap
  • Military, crown property and unique issue, case back engravings

As mentioned earlier due to the conditions they were often exposed to, Milsubs would need to be serviced more regularly than their standard civilian counterparts. Unfortunately this resulted in far fewer watches surviving in their original configuration. Watches in original condition with the full military specification as defined above continue therefore to attract significant premiums.

The Dials

The dials of the Rolex issued military Submariner were standard Submariner dials with a circled T added below the hands and before the ‘SUBMARINER’ model designation.

Between 1972 and 1979, 4 versions of dials were used, as follows:-

Serif

Non Serif

Smudge Crown

Maxi Mk 1

The different dial types were not exclusive to any particular model reference but were relevant to the date of issue of the watch. For example a ‘serif’ dial should really be found on particular batches of the model ref. 5513 until 1977, and then the last batch of 3.9 million double references (5513/5517) issued in 1979. The ‘non-serif’ dial is most often found on watches with serials in the 3.7 and 3.8 million range. The so-called ‘smudge’ or ‘pre-comex’ dials are generally found on watches issued circa 1976/77. The ‘maxi’ dial will feature on watches issued from 1977 onwards. It should be noted that variations on the above exist, as dials may have been swapped or replaced during servicing, especially by MOD watchmakers.

Outer Case Backs

The outer case back on a correct full specification Rolex Milsub will be engraved, depending on whether it was a British Navy (0552) or British Army (W10) issue.

Contrary to popular belief all watches would have been used for diving, as although the W10 deliveries were Army or SAS issue, during the 1970s both units were trained divers, thus the watches were available to divers of either unit.

Milsub engravings

Inner Case Backs

The inner case back on a correct Rolex Milsub will include the following engravings:-

  • Model ref. ‘5513’
  • Date of case/case back manufacture
  • Serial number matching the case (depending on the particular batch. Some known batches did not have the case serial number engraved in the case back)

IMPORTANT: Milsubs sometimes surface with mis-matching serials in the case back, meaning that at some point the case back of one Milsub was incorrectly fitted to the case of another during service by MOD or independent watchmaker. Whilst the mistake is easy to understand, it has a significant impact on the value and desirability of the watch.

Documentation

The original 1970s military Rolex Submariner special deliveries to the MOD for issue to the UKSF were not delivered with the traditional box and papers which accompany the standard model Submariners sold via retailers. However some later documentation can accompany watches which is of particular interest to collectors. This is either in the form of:

  • Documented provenance from the original owner on his service as well as photographs and dive logs. It must be noted though that due to the covert nature of the original owners occupation many prefer to remain anonymous, thus documentation is not easy to acquire.
  • Rolex delivery confirmation letters signed by the former general manager of Rolex UK, Henry Hudson.

In the 1970s it was Mr Hudson’s department who were responsible for delivering the military spec Submariner to the UK military. Although later assuming the post of general manager of Rolex UK, he still retained the original delivery information for each of the issued watches (serial, case back number, unit or dockyard) and until his retirement a few years ago would kindly provide the information where available to owners of the watch via a signed letter on Rolex headed paper.

Unfortunately since his retirement this service is no longer possible. Rolex no longer confirm the original delivery information. Whilst watches with the HH papers as they are referred to do not carry a significant financial premium, collectors like the re-assurance relating to the original issue that it offers. However perfectly correct and collectable examples will continue to surface in the market, sans paper. That does not mean they should not be acquired and enjoyed. We would just advise and recommend that you consult with one of a handful of known specialists (ourselves included) who have been collating the model ref, serial, case back and delivery information for many years and should be able to reassure you regarding the batch that your watch belongs to and any specific nuances you should expect to find.

ROLEX SERIAL NUMBERS & DATE OF MANUFACTURE

How old is your Rolex watch ?

The serial number on any Rolex watch enables you to estimate the approximate date of manufacture. On the majority Rolex watches the serial number is engraved between the case lugs at 6 o’clock just behind the bracelet end links. However on some earlier models (pre 1960) the serial number will be engraved on the outer case back. This 4-8 digit number can be used to determine the date of manufacture. It is important to note however that final assembly, sale and delivery of the completed watch may be some time later. For example a case or case back assembled in 1967, may not have been used on a completed watch until 1970 or sold via a retailer until later still.

From 2005, Rolex started to also engrave the serial number on the inside case rehaut which is found between the dial and the crystal.

From 2008, Rolex started to only engrave the numbers on the rehaut.

From 2011, Rolex started to use a random numbering system, hence in years to go dating your Rolex watch will need to be established by either referring to the original warranty card, understanding the configuration of your particular example or referring directly to Rolex.

SERIAL NUMBER LOOKUP

To identify the date of your Rolex watch manufacture, refer to the following table. The serial ranges listed will provide an indication regarding the date of manufacture. Please note the serial number range Rolex used restarted again circa 1953. Care should therefore be taken when dating watches with serials which could fall into both the pre and post 1953 date ranges provided.

The Rolex ‘Oman’ Sea-Dwellers

The Rolex ‘Khanjar’ & ‘Qaboos’ Sea-Dweller

Muscat & Oman

The state of Oman lies on the Southeast tip of the Arabian Peninsula, a position of extreme strategic importance with regard to the flow of oil through the Gulf. It has long standing military and political ties with the United Kingdom and United States.

Ruled by the Al Bu Sa’idi dynasty since 1744. Oman was once a regional power, with a sultanate that extended to Iran, modern day Pakistan and south to Zanzibar on the coast of southeast Africa. Over time, its power declined and it came under the increasing influence of the United Kingdom.

From 1932 to 1970 Oman was ruled by Sultan Sai’d bin Taimur.

Sultan Sa’id whilst careful to maintain Oman’s relationship with the United Kingdom took little interest in maintaining the ongoing stability of his country. Restricting Oman’s contact with the rest of the world, discouraging development and unable to handle the increasing complexity of domestic politics, Omani affairs became an international concern.

By 1962, Marxist revolutionaries formed the Popular Front for the Liberation of Oman in the province of Dhofar and revolted against the Sultan. Sultan Sa’id survived an assassination attempt but the events had a profound effect, he became more withdrawn and erratic in his governance. No one was safe from the Sultan’s control and increasing paranoia, including his son Qaboos Bin Sa‘id.

Sultan Qaboos & the Coup d’état

Sultan Qaboos Bin Sa‘id (pictured below) was born in Salalah in Dhofar on 18 November 1940. In 1960, at 20 years of age, he entered the Royal Military Academy Sandhurst in England, forming a great friendship with Tim Landon who would become a significant ally in the development of Oman in future years. After graduating from Sandhurst, Qaboos joined the British Army and was posted to the 1st Battalion The Cameroonians (Scottish Rifles), serving in Germany.

On his return to Oman in 1964 Qaboos was placed under house arrest by his father Sultan Sa’id, and remained there until July 23, 1970, when with the support of the British government (who had become increasingly concerned by Sultan Sa’id’s behavior and with Oman on the brink of an oil boom, the British were keen to share) agreed to deploy operatives from the SAS to enable Qaboos with the assistance of his friend Tim Landon to depose his father Sultan Sa’id in a palace coup d’état.

Brigadier Tim Landon, the mysterious ‘White Sultan’ as he became known, is believed to be a key ally in the plot to overthrow the old Sultan and put his son on the throne. A latter-day T E Lawrence, Landon served Britain well through a close bond with the Arab world. He remained a close friend and advisor to Qaboos through-out his life.

The above image is believed to be the only one in existence of Landon, a man who guarded his privacy very closely. It is said that when at home in the UK he would drive a privately owned black London taxi to avoid attention. It is also rumoured that Qaboos would send Landon a gift of £1m GBP each year on his birthday, and on his death in 2007 his wealth was reported to have exceeded that of the Queen.

Following the coup, the deposed Sultan Sa’id bin Taimur went into exile in London and died 2 years later. When asked once of his greatest regret, the Sultan replied: “Not having had Landon shot.”

The New Oman & the SAS

On his ascension to the throne in 1970, Qaboos immediately instigated major social, educational and military reforms, with the intention of ending the country’s isolation and using its oil revenue for modernization and development.

In a further re-branding exercise, he declared that the country would no longer be known as ‘Muscat and Oman’, but would change its name to “the Sultanate of Oman” in order to reflect its political unity, This was complimented by a new flag which replaced the traditional white flag that had been used since 1865. The National flag of Oman circa 1970-1995 featured the 3 colours of Red, White and Green.

The colours of the new flag symbolized the following:-

White = Peace and prosperity
Green = Fertility and the Jebel al Akhdar or Green Mountains
Red = Battles against foreign invaders

and incorporated the national emblem, a Khanjar dagger (pictured below) in a sheath 
superimposed upon two crossed swords.

Qaboos also added a new individual standard for the Sultanate of Oman, which exclusively featured the Khanjar in Gold with Sultans Crown above.

>In addition to implementing the necessary reforms to safeguard Oman’s future, Qaboos faced another issue, the Dhofar Rebellion that had commenced in 1962 was by 1970 growing ever stronger.

The British Military commanders in Oman suggested that a “hearts and minds” campaign code named ‘Operation Storm” be put into operation primarily by operatives from the British Special Forces elite 22nd SAS regiment (Boat, Air, Mobility & Mountain counter terrorism specialists).

Once ‘Operation Storm” was underway, many of the Omani’s who opposed the Dhofar rebels (because of differing beliefs) sided with the SAS who formed them into ‘counter gangs’, using their superior local knowledge, a strategy that had worked well for the SAS in both Kenya and Malaya. The SAS gradually began to occupy commanding positions on the mountain range throughout the Dhofar region, incurring running battles with the Dhofar rebels as they did.

9 SAS vs. 250 Dhofar Rebels

>“It was not our numbers, but our ideas” 

The Battle of Mirbat took place at 6 am on 19 July 1972. It has become one of the most famous standoffs in the regiment’s history; many have compared it to the famous battle at Rourke’s Drift.

A 9 man permanent SAS team had been established at Mirbat earlier in the year. Each team was due to be posted for a three-month tour before being replaced. The occupying team was preparing to leave that very morning, when at about 5:30am a patrol discovered the 250 rebels on a hill to the North of the town.

One of the SAS gunners recalled what happened.

“We opened fire simultaneously, unleashing a hail of .50 cal bullets and machine gun fire at the approaching Adoo rebels. The running figures became a focal point where the red tracer and exploding incendiary rounds converged. Where moments before there had been an orderly advance, parts of the line now faltered and collapsed. Figures staggered, but still they kept coming, wave upon wave over the plain.”

The surrounded SAS troops knew the situation the situation was serious, a frontal assault could only mean they were facing a very large force, a message was sent to the SAS HQ at Salalah. The rebels were well organised, advancing in groups and using high ground to lay down covering fire, by now rounds were coming in from all directions over the forts.

A lull in the fighting as the rebels recovered their wounded allowed two SAS troops to reach the gun pit of an antique 25 pounder (pictured below), which was used to devastating effect on the rebels, but as they fell more replaced them.

The perimeter walls started to collapse under heavy grenade attacks. A helicopter sent by HQ attempted to land on the nearby beach to evacuate the wounded but was hit by enemy machine gun fire and forced to turn back. At the gun pit one of the SAS troops had been killed and the other one bad wound to his chin resorted to firing the gun single handed, with the cannon raised to fire level at point blank range.

The 23 year old SAS captain Mike Kealy radioed for an air-strike, by now the rebels were almost on top of the gun pit, the remaining men continued to pick off the advancing troops despite an almost continuous hail of bullets and grenades. Just as all seemed lost two Strike master jets roared over.

From the radio the jets were given targets, they would have to drop 500lb bombs on positions less than 60 yards from the gun crew. Just the sight of the jets had an immediate effect on the rebels, many began retreating. One jet was hit by heavy machine gun fire and forced to withdraw, more aircraft were called in while the rebels continued to retreat. A squadron based at SAS HQ were also dispatched and landed on the beach after flying in very low to avoid detection. A second air strike began as they were landing.

By 10.30am the rebels were forced to retreat in numbers, the wounded were loaded on to the helicopters and flown back to HQ.

SAS casualties included two dead and two seriously wounded.

In Britain the battle received no publicity, the gallantry awards not awarded until some four years after the event. The 9 SAS soldiers present at the battle of Mirbat on 19 July 1972 were

▪ Captain Mike Kealy

▪ Staff Sergeant Talaiasi Labalaba (Killed in Action) (pictured below)

▪ Sergeant Bob Bennett

▪ Corporal Roger Cole

▪ Lance Corporal P. Warne (aka Pete Wignall or Winner, Soldier I & Snapper)

▪ Trooper Sekonaia Takavesi (Killed in Action)

▪ Trooper Tommy Tobin

▪  Austin “Fuzz” Hussey

▪ Corporal L. M. Taylor (Understood to have been an alias)

Mission Accomplished

When the Dhofar rebellion finally ended in 1976 with the insurgents suppressed, the SAS contingent that had been engaged in the conflict from the time of the coup amounted to around 80 men (supported by Oman locals). The insurgents had numbered almost 15,000, a staggering achievement.

The 22nd SAS Regiment went on to engage in countless other anti terrorist campaigns, and achieved notoriety during the 1982 Iranian Embassy siege which was broadcast worldwide.

Recognition by Gifts

There is a custom in the Gulf of presenting gifts, often watches, in recognition of achievements, appreciation or as a mark of respect. 
British troops on active duty would not normally be allowed to accept such gifts. However in the case of Oman circa 1970-76 the restrictions did not apply. The SAS were never officially on active duty, but in Oman under the cover of the ‘British Army Training Team’ as the official documentation of the time advised.

Two example which we have previously owned and subsequently placed in important collections, provide the perfect opportunity to study further both the Rolex 1665 Red & Gold Khanjar Sea-Dwellers which were presented as gifts to SAS operatives by Qaboos for the 1970-76 Oman campaign.

The Rolex RED ‘Oman Khanjar & Qaboos’ Sea-Dwellers

The Rolex modelref. 1665 Oman Sea-Dwellers with either RED Khanjar or Qaboos dial script, were commissioned by Sultan Qaboos bin Sa’id via ASPREY of London in the early 1970s and presented to the British Military SAS troops who had served in Oman during the Dhofar rebellion between 1970-1976.

Many of the watches that have surfaced, like the one above, are found with a deep patina, due to the humidity in the Middle East being absorbed by the heavy tritium markers.

The configuration of the watches that have surfaced to date is as follows: –

• The Double Red lines, Depth rating and SCOC found on the standard 1665s of the period are absent and in its place the Omani Khanjar or Qaboos signature in bright red script.

• The tritium application on the 5 minute markers is very heavily applied.

• The serial numbers all begin 3,56x,xxx and are engraved between the lugs at 06:00 and inside the inner case back.

• The outer case back has the expected straight ‘Rolex’ style engravings of the period, but also carries the ASPREY engravings in the lower centre.

Following a comprehensive study of the known serial numbers, I believe that upto 90 examples were produced in a consecutively numbered batch starting with serial 3566,9xx and ending at 3567,0xx. Of these estimated 90 examples, approximately 30% are now known. The known watches are evenly represented by either Red Khanjar or Qaboos dials, and the 2 dial variants have been fitted in a random sequence, i.e. we see consecutive serials with either dial, and then small batches of 3-4 watches with one dial type or the other.

The approximate number of watches issued is further supported by the number of SAS soldiers who served in Oman during the period 1970-1976 again reported to be around 80-90 operatives, so the assumption is that each soldier would have been allocated a RED Oman Sea-Dweller in recognition of their services.

The use of the colour Red for the Khanjar or Qaboos signature on the dials is also relevant to the colour of the new Oman national flag during this period. Red symbolized battles against foreign invaders. How very appropriate.

The Rolex GOLD ‘Oman Khanjar’ Sea-Dweller

To date only 5 examples of the Rolex 1665 Omani Sea-Dweller with GOLD Khanjar dial script have surfaced and as such the information on configuration and delivery was something of mystery when compared to its Red counterparts. The watch featured above is the 4th example to have surfaced, with each new discovery aiding our understanding of the batch.

The configuration of the Rolex 1665 Omani Sea-Dwellers with GOLD Khanjar dials that have surfaced to date is as follows:-

• The 2 lines of Double Red Text, Depth rating and SCOC found on the standard 1665s of the period are absent and in place the Omani Khanjar in Gold script.

• The Rolex coronet on the dial is a unique style and different to the Rolex 1665 Oman Red Khanjar or other coronets on the Double Reds of the period.

• The tritium application on the 5 minute markers is absent or minimally applied.

• The serial numbers all begin 5,xxx,xxx

On further analysis of the known watches the serials indicate something more. On 4 of the 5 known watches including our recent acquisition (pictured above) the serials are within the standard Double Red batch of 5,0xx,xxx

I have deliberately omitted the serial numbers, but they indicate a clear timeline.

On these 4 watches the serial number is also engraved between the lugs at 6:00 and inside the case back.

2 of the above 5 watches have been serviced within recent years by Rolex Geneva and records appear correct.

The other known example has a slight variation to the serial, and while close, is slightly later at 5.3xx,xxx. The case back style also differs although consistent with the Great White Sea-Dwellers of this period. The inner case back does not have the serial number engraved inside, which whilst again consistent with a 5,3xx,xxx serial Sea-Dweller, would also indicate that the dial was quite probably not born with the watch but fitted later, as it appears out of batch. However, until more examples surface or the delivery is confirmed by Rolex, it remains only a thought.

So how many were of the Rolex 1665 Omani Sea-Dwellers with GOLD Khanjar dials were produced, and why?

If we assume the same ratio as with the Red Oman watches, i.e. approximately 90 watches produced with 30% of them having surfaced to date, this would indicate a production of Gold Khanjar Sea-Dwellers upto around 15 watches.

Using the historical information provided earlier of Oman during the period 1970-1976, we know that the Gold Khanjar was used only to represent the Sultanate of Oman on the Sultanates official standard, whereas the national flag features the Khanjar in White. If the use of Red on the Red Khanjar / Qaboos Sea-Dwellers is as we believe significant, it would suggest the use of Gold here would also be, possibly to indicate a special presentation directly by Sultan Qaboos himself.

We know that the battle of Mirbat was under-reported and many considered the SAS team deserving of further individual awards for gallantry. However, many in Oman at that time perceived a desire by HM Government and the MoD to downplay incidents of direct involvement of British service personnel in military action. The British Military Intelligence Corporal who received a medal for gallantry from the Sultan at the time was threatened with disciplinary action by the British Army for being directly involved.

So it was not until some 4 years later, after the battle and once the Dhofar rebellion had been suppressed that: –

· Captain Mike Kealy received the Distinguished Service Order.

· Sergeant Bob Bennett was awarded the Military Medal.

The gunners on the 25 pounder

· Trooper Sekonaia Takavesi received the Distinguished Conduct Medal and

· Staff Sergeant Talaiasi Labalaba was awarded a posthumous Mention in Dispatches.

His former comrades have since campaigned for him to be awarded a posthumous Victoria cross.

We know that Qaboos was fully aware of the Battle of Mirbat as he presented an Omani named Walid Khamis, who was injured during the battle, with the Sultan’s Gallantry Medal, Oman’s highest award.

Given that the Battle of Mirbat was pivotal moment in defeating the insurgents, and the lack of recognition given to the SAS soldiers by their own government, it is not inconceivable to think that Qaboos who had previously commissioned the Red Oman watches to commemorate the SAS soldiers who occupied Oman during the 1970-1976 campaign would commission a small special batch to honour the 9 SAS (and possibly others like William Stoker SOAF Strike master Jet commander) who put their lives at risk during the Battle of Mirbat to defend Oman from the rebellion.

Of course without official delivery information from Rolex, Qaboos or the surviving SAS soldiers, we cannot be at all certain, but the theory should encourage further discussion, research and understanding of the events in Oman during the 1970s and the important watches that commemorate the period.

Thank you to Dr. Stephen B, Steven E, Paolo and Marc S for their invaluable contributions.
