Rolex New Oyster Perpetual Deepsea Challenge 50mm Diameter

In 1960, Rolex made several experimental diving watches Deep Sea Specials, which were installed on the US Navy submarine Trieste and dived into the world’s deepest Mariana Trench at 10,908 meters. Since then, it has established its leading position in diving watches. Buy top Rolex clone watches online, buy replica watches at twatchclone.ru.

Titanium is not only more skin-friendly, but also lighter. Compared with the experimental watch that James Cameron carried on his diving expedition in 2012, the weight of the new watch is significantly reduced by 30%. However, although Rolex claims that it is "suitable for daily use", it is undeniable that its actual weight is 251 grams. How does it feel to wear half a catty on your wrist? Everyone may feel differently.

Why is titanium still so heavy? Because in addition to the wearing comfort of the watch, Rolex also considers the waterproof of the watch. The waterproof depth of the new Deep Sea Challenge watch is as high as 11,000 meters, which can be said to have broken the record in terms of mass-produced watches. It is much higher than the 3,900-meter water resistance of the Rolex Deep Dive, which was previously known as the "Ghost King", and it also exceeds the 6,000-meter professional diving watch of the Omega Ocean Universe Ultra Deep.

In order to achieve this waterproof performance, the watch adopts a one-piece middle case, a screw-in bottom cover and a winding crown; a Rolex Ringlock system case structure with a nitrogen alloy steel ring and a helium exhaust valve. This reinforced case structure consists of three parts: a thicker domed sapphire crystal, a pressure ring in nitrogen-alloyed steel, and an RLX titanium caseback.

The watch is equipped with a Rolex 3230 movement, with an average of plus or minus two seconds per day (after the movement is installed in the case), and a power reserve of 70 hours. It has been certified by the Superlative Observatory for precision timepieces. The bottom cover is engraved with the words "Mariana Trench" and the two dates "23-01-1960" and "26-03-2012".
