For professional deep-sea divers, Rolex watches developed the helium escape valve, allowing helium gas to be released without jeopardising the movement.In 1967, Rolex launched the famous Rolex Oyster Perpetual Sea-Dweller as to fulfill the increasing demand for fashionable extreme diving watches. The original Rolex Sea-Dweller was waterproof to 610 metres, with helium escape valve for use during long decompression phases in hyperbaric chambers. In 1978, Rolex launched the Rolex Sea-Dweller 4000 which is water resistant to 1,220 meters/4000 feet. In 2008, Rolex released the world renowned Rolex Deep Sea, which is a divers watch for extreme underwater activities.

In 2012, Rolex was invited to join James Cameron's 2012 Deepsea Challenge submarine adventure to explore the Mariana Trench, 11,000 metres under the sea. As sponsor of this remarkable adventure and valorous underwater companion, Rolex watches launched a new version of its Deepsea diver's model with a symbolic D-Blue dial representing the changing colours of the water as it gradually reaches the black abyss. In view of the Sea-Dweller Deepsea, it highlights an exceptional dial that is dark blue at the top and bit by bit blurs to dark at the base. The configuration speaks to the adjustment in sea shading from the surface to the base.

What the Rolex Sea-Dweller famous is not only for its name, its appearance but also its performance. This kind of domineering watch also catches the love of the world soccer superstar David Beckham. Starting from the date of its birth to develop up to now, the Rolex Sea-Dweller has upgraded to reach 1220 meters, and even reach the 3900 meters. If you need a good watch for diving, then I highly advise you to try a replica Rolex Sea-Dweller, as it also a great choice for the waterproof watch. A quality replica Rolex Sea-Dweller is a beautiful timepiece that looks and feels genuine.
