The launch of the Rolex Submariner in 1953, a professional dive watch capable of fathoming depths of 100 metres opened the hatch on a new underwater world waiting to be explored. Rugged, handsome and ready for any kind of mission, the Submariner caught Ian Fleming’s eye as the ideal watch for his spy positioning Rolex as the original James Bond watch and the rest, as they say, is history. This 40mm steel model is water-resistant to 300 metres and, like all Rolex watches today, a certified Superlative Chronometer. The rotating bezel of the Submariner is filled with a sophisticated black ceramic known as Cerachrom that is scratchproof and corrosion-resistant and the superior luminescence of the watch is thanks to the use of Chromalight, a special material emitting a long-lasting blue glow. This Submariner model is equipped with Rolex self-winding calibre 3130, which harnesses the movements of the wrist to provide a constant source of energy. The Oyster bracelet is attached to the wrist with an Oysterlock safety clasp that prevents accidental opening and features the Glidelock extension system that allows the bracelet to be adjusted in 2mm increments so that it can be worn comfortably over a diving suit.
