The ‘super’ Submariner, boasting a higher water resistance and a date window without a magnified crystal. From its thicker case to the impressive depth rating on the dial, the Rolex Sea-Dweller replica makes no mystery of its raison d’etre: to go deeper than any Rolex Submariner. Since 1967, it has achieved this by integrating a gas escape valve that allows the helium to leave the case during a dive and prevents the plexi from popping up under the pressure.
The first reference, the 1665, was already guaranteed to reach a depth of 2000 feet or 610 meters. But it also offered another advantage - a well-integrated date window without the magnified bubble found on the Submariner Date. Additionally, this dial deserves a long look, as it is the coveted Mark 2 “rail dial” with longer minute markers, similar to the version for Comex, the most famous customer for hardcore Rolex diving watches.
