Steeldive SD1952 Fifty Fathoms Mechanical Watch

Steeldive SD1952 pays tribute to the Fifty Fathoms, developed for the elite divers at the French Combat Diving School. It was one of the first modern diver watches and the first to have a rotating bezel. With a case size of 41mm - the same as the original - it’s a lot more wearable than the 45mm modern interpretations.
