Rolex Sea Dweller Deep Sea 116660 44mm Black Dial

The Rolex Sea-Dweller Deepsea Men’s watch 116660 is an authentic Swiss-made luxury watch that features a 904L Oystersteel stainless case and matching stainless steel oyster bracelet with Oysterlock deployment buckle that includes the new Glide lock extension system. Luminescent hands and hour markers with date aperture at the 3 o’clock position reside on the beautiful deep black.  The case is encompassed by a black Cerachrom insert ceramic bezel with engraved 60-minute scale and graduations. This durable watch is driven by COSC Superlative Chronometer Certified Self-winding movement with a 48-hour power reserve.  The helium escape valve is unidirectional and is automatically activated when the pressure inside the case is greater than the external pressure. It releases the helium atoms, therefore preserving the integrity of the watch during the return to the surface making it waterproof to 1,220 meters or 4,000 feet.
