Born from the record-breaking Five Deeps Expedition in 2019, the OMEGA Seamaster Planet Ocean Ultra Deep made history by reaching the deepest point on Earth. Now adapted for everyday wear, this extraordinary timepiece is part of a public collection that brings deep-sea innovation to the wrist. Engineered and tested under real ocean conditions, it meets the ISO 6425:2018 standard for saturation diving and is water-resistant to an impressive 6,000 metres (20,000 ft). This 45.5 mm model is crafted from O-MEGASTEEL, offering superior strength and corrosion resistance. It features a polished black ceramic bezel with a Liquidmetal™ diving scale. Beneath the domed sapphire crystal, the lacquered gradient dial fades from ocean blue to deep black, complemented by 18K white gold hands and hour markers filled with white Super-LumiNova for optimal legibility. 

The watch is fitted with an O-MEGASTEEL bracelet featuring OMEGA’s patented extendable foldover clasp with fine adjustment and an extra diver extension. On the Grade 5 titanium caseback, a laser-engraved Sonar emblem surrounds the iconic OMEGA Seahorse medallion — a nod to its deep-sea legacy. Powering the watch is the OMEGA Co-Axial Master Chronometer Calibre 8912, delivering exceptional precision and magnetic resistance. The watch will ship with the outer box, Omega display box, Warranty Card, Pictograms Card, Master Chronometer Card, serialized hang tag and The Essential Guide.
