During the 2019 Five Deeps expedition, the Ultra Deep made history by descending to the deepest point on Earth. Following this record-breaking dive, the game-changing watch has been adapted into a unique collection for the general public. Tested in real-world ocean conditions during its development, the watch is water-resistant to 6,000 meters and complies with the ISO 6425:2018 standard for saturation diving watches.
This robust 45.5 mm O-MEGASTEEL model features a polished orange ceramic bezel with a liquid ceramic diving scale and Super-LumiNova. Its domed sapphire crystal covers a white lacquered dial with a gradient effect from grey to black, featuring four orange Arabic numerals, as well as 18K white gold hands and hour markers coated with white Super-LumiNova.
The watch features an O-MEGASTEEL bracelet with a patented OMEGA expandable folding clasp, equipped with a rack and pinion mechanism for size adjustment and an additional extension for diving. The grade 5 titanium medallion on the case back bears the laser-engraved Sonar emblem with the iconic OMEGA seahorse at its center. The watch is powered by the OMEGA Co-Axial Master Chronometer 8912 movement.
