Rolex Oyster Perpetual Sea-Dweller Deepsea

And you thought 1500 meters was deep? Well Rolex just notched it up to a new extreme for Fall 2008 with their Oyster Perpetual Sea-Dweller Deepsea. Clocking in at 3900 meters (that’s 2.42 miles!) of superior waterproof-ness, the new Deepsea introduces Rolex’s new Lockring System. We’ll let them tell you what that means:

“The high-performance ring Set inside the middle case of the watch between the crystal and the case back, the high-performance nitrogen-alloyed stainless steel ring withstands the pressure exerted by water on the crystal and the case back. The middle case is made from 904L steel.  The sapphire crystal To resist pressure, the synthetic sapphire crystal is slightly domed and substantially thicker than the crystals of other Oyster models. The case back The case back is made of a titanium alloy, an extremely resistant stainless material. It is held in place against the high-performance ring by means of a 904L-steel ring.”
