Brand RX Model Challenge Case Size 50 MM Movement Swiss Bracelet Type Steel Colour Silver Dial Black Gender Men Diamond No The groundbreaking performance of RLX Titanium The Deepsea Challenge marks a historic milestone as the first RX made entirely from RLX titanium. This choice of material makes the watch surprisingly light and comfortable on the wrist despite its robust dimensions - around 30% lighter than the experimental steel prototype. The intense satin finishing gives the model a technical, matte aesthetic that sets it apart visually from traditional polished watches. Built for the deep: 11,000 metres Designed to withstand the extreme pressure of the deep sea, this model is water-resistant to an incredible depth of 11,000 metres. At the heart of this resistance is the patented Ringlock system, which uses a nitrogen-alloyed steel ring to absorb the pressure on the 9.5mm-thick sapphire crystal. In addition, the helium escape valve ensures that excess gas can safely escape during decompression without damaging the case. Imposing presence and Calibre 3230 At 50mm in diameter, this is the largest commercial watch in RX's history and ensures maximum readability thanks to the long-lasting blue glow of the Chromalight display. This giant is driven by the in-house Calibre 3230, equipped with the Chronergy escapement and the blue Parachrom hairspring, offering the highest precision and a power reserve of around 70 hours.
