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

Born from the legendary Five Deeps Expedition of 2019, the Ultra Deep forever secured its place in history as the first watch to descend into the deepest known point on Earth. After that record-breaking achievement, this extraordinary timepiece has been reimagined as a rare and exclusive collection for discerning connoisseurs, bringing a piece of oceanic history to the wrist.

Tested in unforgiving real-world conditions, the Ultra Deep is engineered to perform where few dare to venture. Certified to the ISO 6425:2018 standard for saturation divers’ watches and water-resistant to an astonishing 6,000 metres (20,000 ft.), it is a masterpiece of endurance and precision.

This commanding 45.5 mm model, forged in resilient O-MEGASTEEL, is accented by a polished black ceramic bezel, its diving scale rendered in shimmering Liquidmetal™. Beneath the bold, domed sapphire crystal lies a lacquered gradient dial, shifting hypnotically from oceanic blue to abyssal black, adorned with 18K white gold hands and hour markers, each enhanced with radiant white Super-LumiNova for peerless legibility in the dark.

The integrated O-MEGASTEEL bracelet delivers both strength and refinement, equipped with OMEGA’s patented extendable foldover rack-and-pusher system, offering seamless length adjustment and a dedicated diver’s extension for ultimate versatility. Turning the watch reveals a striking Grade 5 titanium caseback, engraved with a precision laser-cut Sonar emblem, its centre proudly bearing the iconic OMEGA Seahorse.
