If you ask any seasoned Rolex or Tudor collector which area of this crazy hobby is the most secretive and shrouded in mystery, they will inevitably reply with the murky world of military watches and in particular Submariners; know as MilSubs. The four most knowledgeable and influential Rolex MilSub collectors in the world are good personal friends of mine and I have literally seen dozens of their watches over the years… and I still am a little baffled by the details. I am, however, very familiar with Tudor MilSubs, which are in many ways a broader subject than their Rolex cousins as they were much more widely issued to a range of military forces around the world.
So where do we start with the Tudor MilSubs? Well, the most important place is the caseback — that’s the key to the Tudors. The British MOD asked Rolex to produce watches that met very detailed specifications and Rolex responded with the military-only versions of Submariner refs. 5513, 5517 and the double reference 5513/17. These watches had to have a specified hand shape (for visibility), 60-minute bezel markers (for accuracy), fixed lug bars (for security) and a circled T on the dial to denote the use of tritium lume on the hands and hour markers.
The casebacks were also fully engraved, but from the front the watches were clearly different to a civilian Rolex Submariner 5513. The military departments that decided to issue their troops Tudor Submariners were a lot less specific in their requirements and were happy to issue their troops standard Tudor Submariners, but they tended to engrave the casebacks to keep track or show ownership of the watches. And so the fun begins…
