Last May, American adventurer Victor Vescovo established the new world record for the deepest dive achieving a depth of 10,928 meters / 35,853 feet. During a 12-hour mission, he successfully piloted his submersible Limiting Factor to the bottom of the Mariana Trench, the deepest point on planet Earth and the first of five manned expeditions to reach the deepest point in each of the five oceans.

Along for the ride – and performing perfectly at depth – was Omega’s Seamaster Planet Ocean Ultra Deep Professional – more advanced version of their iconic Semaster. In order to create a timepiece suitable for The Five Deeps Expedition, Omega introduced new technologies that could be adapted to dive watch manufacturing in the future.
To withstand the exceptional pressures and loads on the watchcase, Omega’s Ultra Deep was subjected to extensive finite element analysis simulations with the goal to limit the thickness of the timepiece as much as possible without sacrificing its resistance. The result was remarkable as the watch is only 28 mm thick. The bezel body, casebody, caseback and crown of the watch were machined cutoffs from the grade 5 titanium hull of the Limiting Factor submersible.

The expedition logo is located at the center of the caseback inside concentric circles evoking the Multi Beam sonar technology. Relevant information including the model, reference number, materials, DNV-GL certific...
