As part of the Five Deeps Expedition in 2019, the Ultra Deep made history when it reached the deepest place on Earth. Following that World Record dive, the game-changing watch has now been adapted for a unique collection available to the public. Tested in real ocean conditions during its development, the design is water-resistant to 6,000 metres (20,000 ft.) and meets the ISO 6425:2018 standard for saturation divers’ watches.
This 45.5 mm model in robust O-MEGASTEEL features a polished black ceramic bezel with its diving scale in Liquidmetal™. Through the protuberant and domed sapphire crystal, the lacquered gradient dial transitions from blue to black, and has been given 18K white gold hands and hour markers, which are all coated with white Super-LumiNova.
The watch is set on a rubber strap with cyan lining and an O-MEGASTEEL buckle, while on the caseback's Grade 5 titanium medallion, there is a laser-engraved Sonar emblem with the iconic OMEGA Seahorse at its centre. Inside, the watch is driven by the OMEGA Co-Axial Master Chronometer Calibre 8912.
