Rolex SEA-DWELLER 4000 - Ref. 116600

At Baselworld in 2014, Rolex revealed an entirely new Sea-Dweller to a gushing reception. The Sea-Dweller 4000, as it is called, picks up right where its forebears left off – a 40mm case made from 904L steel, the trademark gas release valve and 1,220m of water resistance. But while the prior Sea-Dweller belonged to an earlier generation of Rolex dive watches, the new one bears the traits of a new era. Wider lugs give the watch a burlier profile, an engraved ceramic timing bezel replaces the now-quaint old painted aluminum one, and inside ticks the Rolex caliber 3135 with a blue Parachrom hairspring that is immune to the effects of magnetism. The steel bracelet is a quantum leap forward from its historical forebear. Solid links are held together with screws and the clasp has a foldout dive extension as well as Rolex’s Glidelock adjustment mechanism that allows for quick fine-tuning. While many newer dive watches have adjustable clasps, none are as easy to use as the Glidelock.
