Deepest watch [Prototype]

Last updated: November 10, 2017 at 20:52 pm

On January 23, 1960, a ROLEX Deep Sea Special third-generation prototype watch was strapped to the bathyscaphe Trieste which descended to 10,916 m (35,814 ft) in the Challenger Deep (Mariana Trench). The watch returned to the surface in perfect working order. The Challenger Deep is the deepest known point on earth with a hydrostatic pressure of 16,000 PSI (1,089 ATM). PSI: Pounds per square inch. ATM: Unit of pressure roughly equal to the average atmospheric pressure at sea level on Earth.

The ROLEX Deepsea Challenge experimental watch was created for James Cameron’s record solo dive in the Challenger Deep. On March 26, 2012, it was observed working precisely on the Deepsea Challenger‘s manipulator arm at a depth of 10,898 m (35,756 ft).

The depth of 35,797 feet in the ROLEX ad in the photo gallery was later revised to 10,916 m (35,814 ft).
