Blancpain Fifty Fathoms - Unsigned
LIP Blancpain watches were not the first dive watches on the market when they were introduced in 1953. They were, however, the most modern dive wristwatches at that time. The reliability and compactness of Fifty Fathoms models, which were originally designed for military use, became legendary. The reputation earned them the right to be used by armies such as French Navy, Czech, Polish, German federal, some Nordic countries, and also by the US Navy (SEAL, under water demolition team, Frogman).
