Well known by military aficionados, it is well known that the military Submariners is one of the most collected with approximately 1200 pieces total between the 3 references (5513, 5513/5517 and 5517) delivered to the UK special forces. Often some of the Military issued watches were decommissioned after use with many of the military parts being replaced with "civilian" parts. To find an original Rolex "T" dial is extremely rare and is perfect to complete a project or just as an extremely rare spare part in excellent original condition with beautiful cream patina.
