ROLEX SEA-DWELLER AND ROLEX DEEPSEA
Manufacturers of professional divers’ watches essentially measure their products against these two Rolex models. While the case of its “little sister” (the Submariner) is 12.5-mm slim and can pass as a sporty and elegant dress watch, the approximately 15-mm-thick Sea-dweller (shown at right in its brand-new version) and the whopping 17.7-mm-thick Deepsea (below) are genuine professional instruments. The Sea-dweller stays watertight to 1,220 meters while the Deepsea keeps its feet dry all the way down to 3,900 meters. Outstanding features of these 43-mm and 44-mm models include Rolex’s special stainless-steel alloy (which is uncommonly resistant to corrosion by seawater), scratch-resistant bezels made from a ceramic developed by Rolex, an automatic manufacture caliber with chronometer certification, helium valves, and folding clasps with intelligently conceived divers’ extensions. The many technical advantages help justify the price: $11,350 for the Sea-dweller and $12,050 for the Deepsea.
