The astounding Rolex Sea-Dweller Deepsea timepiece commemorates director / explorer James Cameron’s 2012 deep dive to the Mariana Trench. As such, it boasts a phenomenal 3900 m / 390 atm water resistance—that’s 12,800 feet! Rolex’s Ring Lock System ensures unwavering integrity at such extraordinary depths.

Additional dive features include a helium escape valve, a screw-down and protected winding crown, a solid case back, and a unidirectionally rotating stainless steel bezel with ceramic insert that displays a convenient dive scale.

The lovely vibrant blue gradient dial sports hour markers and hands filled with Chromalight lume for easy viewing in low light as well as a date window at 3.

Its stainless steel case measures 44 mm in diameter, a robust 17.5 mm in height, and rests upon a stainless steel oyster bracelet with oyster clasp. The 5 mm-thick scratch-resistant sapphire crystal is built to withstand the immense pressures of the deep.

As an officially certified superlative chronometer, this Sea-Dweller Deepsea watch by Rolex delivers accuracy that you can depend upon. It is driven by Rolex’s self-winding automatic 3135 caliber, which offers a 48-hour power reserve.

Standout feature(s): Astounding 3900 m / 390 atm water resistance; attractive gradient blue dial; officially certified superlative chronometer; helium escape valve and protected screw-down winding crown.
