Rolex Deepsea Sea-Dweller Mens Watch. 
The Rolex 116660
Adorned with an Oyster bracelet, this model of the Rolex Deep Sea collection is nothing short of classic. Its simple yet timeless design adds to the elegance of the watch. Set in a stainless steel case, the dial of the watch is a perfect deep blue color. The silver-toned dot hour markers and hands enhance the depth of the color. All this topped with a scratch-resistant sapphire crystal makes sure that the watch survives the roughest of conditions. The watch also features the date at the 3’oclock marker and is up to 3900 meters water resistant. Truly a great piece to own!  It features a D-blue dial and large luminescent hour markers. Waterproof to a depth of 3,900 metres (12,800 feet) with a unidirectional 60-minute rotatable bezel, the Rolex Deepsea is amongst the ultra-resistant divers’ watches engineered by Rolex for deep-sea exploration.
