Description

The first waterproof diver's watch in history, the Rolex Submariner, was introduced in 1953 with the reference 6204. This model had a stainless steel strap and a sturdy case that allowed it to be worn at depths of up to 100 meters. Later, its water resistance was increased to 300 meters. Divers can track their dive times and decompression stops using its unidirectional rotating bezel.
