The Omega Seamaster Planet Ocean Ultra Deep 6000M is a groundbreaking professional dive watch born from the historic 2019 Five Deeps Expedition — the mission that reached the deepest point on Earth. Adapted from the record-setting prototype, this public-release model preserves the same spirit of extreme engineering, tested in real ocean conditions and certified to an astonishing 6,000 meters of water resistance under ISO 6425:2018 standards.

Crafted from sand-blasted Grade 5 Titanium, the 45.5 mm case is lightweight yet immensely strong, featuring Omega’s signature “Manta Lugs” that secure a striped black-and-cyan NATO strap. A brushed black ceramic bezel with Liquidmetal™ diving scale surrounds the domed sapphire crystal, which reveals a black ceramised titanium dial accented by cyan numerals, a white-to-cyan gradient seconds hand, and 18K white-gold markers coated with Super-LumiNova for exceptional visibility.

Inside, the watch is powered by the METAS-certified Omega Co-Axial Master Chronometer Calibre 8912, offering superior precision, magnetic resistance, and a 60-hour power reserve. The Grade 5 titanium caseback features a laser-engraved Sonar emblem with the iconic Seahorse, commemorating Omega’s deep-sea heritage.
