Seamaster Planet Ocean Ultra Deep 6000m Co-Axial 45.5mm

Born from adventure and engineered for the extremes, the OMEGA Ultra Deep made history in 2019 as part of the Five Deeps Expedition, conquering the deepest point on Earth. Now, this extraordinary achievement has inspired a public collection that combines cutting-edge technology with oceanic heritage.

Tested in real-world deep-sea conditions, the Ultra Deep is water-resistant to an astonishing 6,000 metres (20,000 ft.) and fully compliant with the ISO 6425:2018 standard for saturation divers’ watches. This 45.5 mm model, crafted in ultra-durable O-MEGASTEEL, features a polished blue ceramic bezel with a white enamel diving scale.

Its lacquered white dial, visible through the protuberant domed sapphire crystal, is marked by four bold blue Arabic numerals and 18K white gold hands and hour markers, all coated with white Super-LumiNova for exceptional legibility under any light. The watch is secured with a robust rubber strap lined in blue, complemented by an O-MEGASTEEL buckle, while the Grade 5 titanium caseback features a laser-engraved Sonar emblem surrounding the iconic OMEGA Seahorse, a tribute to its pioneering heritage.

Powering this deep-sea marvel is the OMEGA Co-Axial Master Chronometer Calibre 8912, delivering exceptional precision, reliability, and resistance to magnetic fields. The Ultra Deep is more than a watch; it is a testament to human exploration, technical excellence, and OMEGA’s unrivalled mastery of the ocean’s extremes.
