Seamaster Planet Ocean Ultra Deep

The Omega Seamaster Planet Ocean Ultra Deep 6000M reference 215.30.46.21.06.001 represents the most extreme expression of Omega’s professional dive watch engineering. Designed to endure the harshest underwater environments, this model is offered as a certified pre-owned luxury watch in new condition, complete with its original box and papers (full set).

The watch features a substantial 45.5 mm case crafted from O-MEGASTEEL, Omega’s proprietary alloy developed for superior strength, corrosion resistance, and a distinctive bright finish. Built to exceed professional standards, this Ultra Deep is engineered to withstand an extraordinary water resistance of 6,000 metres (600 bar) and complies with ISO 6425 requirements for saturation diving. The fixed bezel is fitted with a brushed ceramic insert and Liquidmetal™ diving scale, while the case construction incorporates Omega’s Naiad Lock caseback system to ensure optimal sealing and precise alignment.

The dial is finished in a refined grey tone, inspired by deep-sea exploration, and features bold applied hour markers and hands filled with Super-LumiNova for exceptional legibility in total darkness. A domed sapphire crystal protects the dial, specifically engineered to resist extreme pressure. This reference is fitted with an integrated O-MEGASTEEL bracelet, offering robustness, comfort, and visual continuity with the case.

Powering the Ultra Deep is the Omega Co-Axial Master Chronometer calibre 8912, an automatic movement certified by METAS. It delivers a power reserve of approximately 60 hours, outstanding precision, and resistance to magnetic fields up to 15,000 gauss, representing the highest standards of modern Swiss watchmaking.

Presented as a pre-owned luxury watch in new condition and delivered as a full set, this Seamaster Planet Ocean Ultra Deep 6000M is a landmark professional instrument from Omega, ideal for collectors seeking ultimate technical capability, innovation, and uncompromising performance.
