The Rolex Deepsea owes its exceptional strength, waterproofness and pressure resistance to the exclusive Ringlock System. This innovative case architecture patented by Rolex enables the watch to resist the massive pressure exerted by water at the depth of 3,900 metres (12,800 feet), equivalent to a weight of approximately four tonnes on the watch. A high-performance nitrogen-alloyed stainless steel ring serves as the backbone of this system: placed in the middle of the watch, it bears all the pressure exerted by water on the 5.5 mm thick crystal and the titanium case back.
