The Sea-Dweller is a saturation diving model developed for professional divers who work in deep seas.
The most important feature is the automatic helium discharge valve on the side of the case.
When depressurizing, it releases the helium accumulated inside the watch and prevents damage to the windshield.
It boasts a water resistance of 1,220 meters, and the large 43mm case is equipped with a cyclop lens to ensure visibility.
The "SEA-DWELLER" notation engraved in red is a Mage to the first generation, and it is a high-end diver that sublimates the functional beauty of the Submariner even more stoically and professionally.
