This pioneering timepiece became world-renowned after its successful deployment in the 2019 Five Deeps Expedition. It has since been adapted to create a unique collection that is now available to the public. Proven in true deep-sea testings, the device is water-resistant up to 6,000 metres and is in compliance with ISO 6425:2018: the standard for saturation watches.
O-MEGASTEEL construction defines this robust 45.5 mm model, featuring a polished black ceramic bezel and Liquidmetal™ diving scale. The domed sapphire crystal reveals a transitioning gradient dial from blue to black, accented with 18ct white gold hands and hour markers, treated with white Super-LumiNova for clarity.
The timepiece is presented on a rubber strap with a cyan lining and O-MEGASTEEL buckle, and the Grade 5 titanium medallion on the caseback features a laser-engraved Sonar emblem with OMEGA's iconic Seahorse at its center. Achieving power within is the OMEGA Co-Axial Master Chronometer Calibre 8912.
