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

The OMEGA Ultra Deep is a revolutionary timepiece born from exploration at the very limits of our planet. As part of the Five Deeps Expedition in 2019, it made history by reaching the deepest point on Earth, setting a world record for submersible watches. Now adapted into an exclusive collection for discerning collectors, the Ultra Deep combines legendary performance with modern refinement.

Engineered for the most extreme environments, the watch is tested in real ocean conditions, 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 robust O-MEGASTEEL, features a polished blue ceramic bezel with a white enamel diving scale.

Beneath the protuberant, domed sapphire crystal, a lacquered white dial is accented with four blue Arabic numerals and 18K white gold hands and hour markers, all coated in luminous white Super-LumiNova for exceptional legibility at any depth. The watch is paired with an O-MEGASTEEL bracelet, featuring OMEGA’s patented extendable foldover rack-and-pusher system, offering complementary length adjustment and an extra diver extension for ultimate versatility.

On the reverse, a Grade 5 titanium medallion bears a laser-engraved Sonar emblem, with the iconic OMEGA Seahorse at its centre. At its heart, the Ultra Deep is powered by the OMEGA Co-Axial Master Chronometer Calibre 8912, delivering unparalleled precision, reliability, and resilience under the most extreme conditions.
