Specialist Notes
In the 70s the British Ministry of Defense commissioned Rolex for a watch with strict military specifications: fixed spring bars welded to the lugs for greater robustness, a 60-minute calibrated bezel insert, large sword-shaped hands for enhanced readability, and a luminous dial marked with an encircled "T" indicating the use of tritium.Rolex modified its Submariner 5513 with the above requirements, and the "MilSub" was born.When decommissioned these watches -according to research about 1200 units- were sold by the MOD during the 80s, and purchased by civilians and dealers who often replaced the military-specific components to transform them into standard Submariners. Thus, very few MilSubs have survived with their military configuration.The present specimen features all the correct Milsub characteristics and excellent conditions, and it is correctly marked with the "0552" code for British Ministry of Defense, the "923-7697" code for NATO, followed by the issue number "370" and year of issue, "75".
