Rolex Sea-Dweller Deepsea  boasts an innovative design that allows it to withstand the pressures of up to 12 800 feet below the ocean's surface via a Triplock screw-down crown with three waterproof zones a Titanium screw-down case back a thicker 5mm sapphire crystal and a Ring Command System. The case is also equipped with a Helium Escape Valve which slowly releases the gases that accumulate within the case as the wearer performs deep saturation dives. This vital feature keeps the crystal intact thus allowing the wearer to dive deeper than ever before.
