The Rolex Deepsea Challenge

Rolex Deepsea Challenge is an experimental divers' watch produced by Rolex to reach the Challenger Deep, the deepest known point in the Earth's seabed hydrosphere, in the Pacific Ocean, at the southern end of the Mariana Trench. The Challenger Deep is a small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench. Its bottom is about 11 km (7 mi) long and 1.6 km (1 mi) wide.

On 26 March 2012, the Canadian film maker and director James Cameron reached the bottom of the Challenger Deep. Cameron descended 10,908 m (35,787 ft) with a solo submersible called Deepsea Challenger. On its robotic manipulator arm, has been carried the Rolex Deepsea Challenge.

Features of the watch

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. For this reason, the watch is bigger than any other Rolex regularly produced.

To manage this extreme pressure, the Deepsea Challenge features a sapphire of 14.3 mm thick, a case of 51.4 mm diameter and a total thickness of 28.5 mm. The case has the Ringlock System, a special ring used for the first time in the Rolex Seadweller Deepsea 116660. The Deepsea Challenge has a load resistance of 13.6 tonnes, a Rolex crown Triplock and the incredible Waterproofness of 12,000 m (39,370 ft).
