Strapped to the submersible was a new experimental Omega dive watch, the Seamaster Planet Ocean Ultra Deep Professional, which is now officially the deepest diving watch of all time.
The Ultra Deep Professional measures 28mm thick and was constructed with Grade 5 titanium sourced from cutoffs from the submersible.
The sapphire-to-case assembly of the watch was also inspired by the design of loadbearing conical viewports on the submersible to make it capable of withstanding extreme pressure.
The underwater mission was carried out over a period of over 12 hours and saw the intrepid team descend to the bottom of the Eastern Pool of Challenger Deep in the Mariana Trench in the western Pacific Ocean – the deepest known point on our planet.
During the expedition the submersible reached a depth of 10,928 metres below the ocean’s surface, creating a new world record.
The record for the deepest diving watch was previously held by the legendary Rolex Deepsea Special that reached a depth of 10,916 meters back in 1960.
Founded in 1848, Omega has grown to become one of the world's most famous watch brands.
