The Rolex Deepsea designed for extreme underwater exploration and uses the patented Ringlock System for the most advanced divers in the world. This beautifully designed watch can withstand the colossal pressure of the sea 3.900 meters (12,000feet) deep.
The Rolex Deepsea is also equipped with a unique bracelet, featuring a double extension system for a perfect fit over any diving suit. If that wasn’t enough to wet your tastes buds this watch is also equipped with a Helium Valve. If the outside of the watch reaches 3 to 5 bars the valve opens to release helium stored in the watch. This pressure system keeps the watch safe from decompression damage.
Taking as their starting point the diameter of the movement and dial of the ROLEX DEEPSEA, the design engineers calculated the technical dimensions required to resist the shock of the 1,500-bar pressure test. At a depth of 15,000 metres, the load exerted on the crystal is 17 tonnes and on the case back nearly 23 tonnes; the equivalent of about 10 SUVs piled on the watch.
Most Rolex watches have about the simplest backs in the Swiss industry, but not the DEEPSEA with its hallmark titanium alloy caseback and engraved lettering. It is obvious that the lettering is poorly painted on the fake and has already started to wear out. When you tilt the watch and look at the back from different angles (at least under office fluorescent lighting) the titanium alloy caseback on the genuine keeps its darkish hue consistently when you rotate it. The fake on the other hand was either anodized or thinly coated steel; the color changed much more dramatically as it picked up shadows and lighting differences. We also found poor machining on the central area of the caseback, you could feel with your thumb that it wasn’t flush.
