The Ultra Deep, used during the Five Deeps Expedition in 2019, famously reached the deepest point on Earth, making history. Now available to the public, this groundbreaking watch has been specially designed and tested to withstand extreme ocean conditions up to 6,000 metres (20,000 ft.) and is compliant with the ISO 6425:2018 standard for saturation divers' watches.

This robust 45.5 mm O-MEGASTEEL watch showcases a polished orange ceramic bezel that contains a diving scale made of liquid ceramic and Super-LumiNova. The gradient dial, transitioning from grey to black, is visible through the protuberant and domed sapphire crystal. The lacquered dial features four Arabic numerals in orange, along with 18ct white gold hands and hour markers, all coated with white Super-LumiNova.

The watch features a rubber strap with orange lining and an O-MEGASTEEL buckle, and the Grade 5 titanium medallion on the caseback showcases a laser-engraved Sonar emblem with the iconic OMEGA Seahorse. Powering the watch is the OMEGA Co-Axial Master Chronometer Calibre 8912.
