Submariner By Rolex

Rolex, a Swiss watch company, makes the Submariner model as one of their Oyster Perpetual watches designed for diving and known for their resistance to water. Built from the drawing board as a water proof watch, The Submariner was first to market and certified in pressurized tanks The watch is one model from The Oyster Perpetual type

The Rolex Submariner has seen many types of hardship accompanying explorers on their journeys. In one expedition The Submariner held up to over one thousand dives. The eminent scientist, Thor Heyerdal wore a Rolex Submariner in his 1970 Ra II sea expedition. It was the watch Sean Connery wore as James Bond.

The original Submariner was certified for depths of 330 feet however over the next ten years the watch was redesigned, improved and had better works. For The Submariner's 50th birthday a new model was created. It has a green bezel and large dial. The Submariner is waterproof to a maximum depth of 300 metres/1000 ft. Three dots on the crown signifies that the watch has a three gasket protection system it will then be able to tighten against the case tube as well as the Oyster case for a better seal. The case itself is made of 904L stainless, platinum or gold. This is a very anti-corrosive stainless alloy. Rolex makes its gold in its own foundry where it can create new alloys and control the quality of the gold. The Submariner utilizes a unidirectional bezel that enables the diver to calculate immersion time. The bezel is one directional to make sure you can never increase your underwater time by accident. The Perpetual rotor is the self-winding wrist watch mechanism which allows the watch to run continuously because every slight movement of the wrist winds the movement and the rotor builds up tension in a mainspring in the watch that can then help the watch to keep running at times when it is not being used, Every watch has a movement that has been certified by the COSc as a Swiss chronometer. Each night the calendar moves itself to the next day in one rotation. In 1971 Rolex made a stronger Submariner with a thicker case and crystal, they call it The Sea Dweller. To this watch Rolex built in a helium escape valve for use in saturation diving. These watche are rated for dives as deep as 4000 feet.
