The newest Sea-Dweller Available now

In the mid-1960s, Rolex supplied the Comex with a specially equipped Submariner model to test helium escape valves. Today, these “Rolex Comex” watches are both expensive and rare. The Sea-Dweller went into mass production in 1967 and was equipped with a helium escape valve. The new watches are capable of withstanding pressures up to 610 meters deep. Currently measuring 43mm in diameter and 15mm in height, with the iconic Rolex Cyclops date magnifier, the watch looks like an enlarged Submariner, but with a continuous 60-minute scale on the diver’s bezel and red lettering on the dial.
Until 2008, when the Deep Sea model was introduced, the maximum depth limit remained unchanged and the water resistance was 3,900 meters. Rolex has developed a new case design to ensure that the watch is not too big for the huge water-resistance. The system is surrounded by the 904L steel that fake Rolex uses for the case. The titanium case back is pressed into the inner bezel via a threaded 904L steel back ring.
These materials have been carefully selected to exhibit strength and flexibility at the same time, and they are not prone to deformation or breakage under pressure. The complex design makes the 44mm by 18mm case both striking and 10% thinner than other cases of similar construction. The Deep Sea watch is designed to withstand depths of up to 4,900 meters. Each replica watch is subjected to rigorous underwater testing at this 25% higher pressure.
In 2012, another important underwater project was ushered in – the Deep Sea Challenge. And Rolex is once again a partner. Filmmaker James Cameron was the first person to successfully reach the deepest depths below sea level since the first famous expedition in 1960.
