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 sand-blasted Grade 5 Titanium features a brushed black ceramic bezel ring with its diving scale in Liquidmetal™. Through the protuberant and domed sapphire crystal, there is a black ceramised Grade 5 titanium dial with a gradient white-to-cyan central seconds hand, cyan Arabic numerals, as well as 18K white gold hour/minute hands and hour markers, which are all coated with white Super-LumiNova. The watch includes distinctive “Manta Lugs” at each end of the case, which hold on to a striped black and cyan polyamide NATO strap with a loop and buckle in Grade 5 Titanium. On the caseback, there is a Grade 5 titanium medallion, laser-engraved with a Sonar emblem featuring the iconic OMEGA Seahorse at its centre. Inside, the watch is driven by the OMEGA Co-Axial Master Chronometer Calibre 8912.
