Pressure, an immutable force of nature The ultimate diver, the Oyster Perpetual Deepsea Challenge is an extension of the experimental watch created in 2012 to accompany James Cameron in the Mariana Trench. It is a watch that pushes back the frontiers of innovation, as capable of resisting abyssal pressure as preventing the adverse effects related to helium. This gas, necessary for saturation diving, is composed of atoms that are so tiny they can penetrate the watch case through its waterproof seals when in a hyperbaric chamber. If helium remains trapped in the watch, it can damage it, even separating the crystal from the case during the decompression process. The helium escape valve thus allows the gas to be released without compromising the watch’s waterproofness. A guarantee of trust for underwater explorers, the Deepsea Challenge is also a source of daily inspiration for everyday wearers on their quest to defy the limits.
