OMEGA Seamaster Planet Ocean Ultra Deep Automatic – 215.32.46.21.04.001

Crafted for explorers and professionals alike, the OMEGA Seamaster Planet Ocean Ultra Deep is a remarkable timepiece born from history. Originally developed for the Five Deeps Expedition in 2019, this watch made a record-breaking descent to the deepest point on Earth. Now refined for everyday adventurers, it brings cutting-edge technology and impeccable craftsmanship to your wrist. Engineered to perform under the most extreme conditions, it’s water-resistant up to 6,000 meters (20,000 feet) and certified to meet the rigorous ISO 6425:2018 standard for saturation diving.

This 45.5 mm model features a case made from O-MEGASTEEL—a proprietary alloy known for its strength and brilliance. A polished blue ceramic bezel with a white enamel diving scale frames the domed sapphire crystal, which reveals a crisp lacquered white dial. Blue Arabic numerals, paired with 18K white gold hands and hour markers, all glow with white Super-LumiNova for optimal visibility. A matching rubber strap with a blue lining and O-MEGASTEEL buckle completes the sporty yet refined look.

The Ultra Deep is powered by the OMEGA Co-Axial Master Chronometer Calibre 8912, delivering exceptional precision, anti-magnetism, and a 60-hour power reserve. A titanium medallion on the caseback is laser-engraved with a Sonar emblem and the iconic OMEGA Seahorse—honoring its deep-sea legacy. Whether you're diving into the ocean or elevating your everyday style, this watch is a true testament to innovation and endurance.
