About this watch

The Omega Seamaster Planet Ocean Ultra Deep O-Megasteel embodies both adventure and elegance with its striking design, robust features, and precision movement. Crafted from proprietary stainless steel, this watch is built for those who live life on the edge. The rotating bezel features a 0-60 dive scale, allowing divers to track their underwater time accurately. With an astounding water resistance of 6000 meters, this watch isn't just a pretty face. It's designed for the serious diver. Whether you're exploring the depths of the ocean or caught in a rainstorm, the Ultra Deep has you covered. The dial is where the magic happens with mixed indexes providing an intriguing contrast against the white background, ensuring readability even in low light. The Omega Caliber 8912 automatic movement is a marvel of engineering, offering features like a Co-Axial escapement and chronometer certification. With a power reserve of 60 hours, this movement ensures that your watch will keep ticking even if you take it off for a weekend. Wearing a watch as robust as the Ultra Deep might raise concerns about comfort, but Omega has nailed it with the rubber strap. The combination of O-Megasteel and ceramic not only enhances the watch's aesthetic appeal but also adds an extra layer of protection against the elements.
