Tudor's history began with the first Submariner watch in 1954. It has undergone some forty-five years of evolution, during which various elements have been improved, always prioritizing what professional divers were looking for, and with the French Navy as its partner. The 9401/0 was launched in 1976 as an undated Submariner. It was available with blue and black dial and bezel combinations, with square hour-markers and "Snowflake" hands. From a collector's point of view, this watch, like the rolex submariner, has become an increasingly rare and exceptional piece.
