The Omega Seamaster Planet Ocean Reference 2201.51 is a robust and purpose-built dive watch that exemplifies Omega’s modern professional tool-watch pedigree. Introduced as part of the first generation Planet Ocean collection, this model combines serious underwater capability with a clean, timeless aesthetic that has become a favorite among enthusiasts.

Housed in a 42mm stainless steel case, the watch features a black dial with bold Arabic numerals and luminous hands and markers for exceptional legibility in low-light conditions. The black unidirectional dive bezel with contrasting numerals reinforces its utilitarian character while maintaining a refined appearance. A screw-down crown and helium-escape valve underscore its professional credentials.

At its heart is the Omega Caliber 2500 automatic movement, equipped with Omega’s Co-Axial escapement for enhanced long-term accuracy and reduced friction. The watch is water-resistant to 600 meters (2,000 feet), making it a true deep-sea instrument rather than a mere desk diver.

Balancing rugged performance with everyday wearability, the Omega Seamaster Planet Ocean 2201.51 is a modern classic—ideal for collectors seeking a first-generation Planet Ocean with timeless design, proven reliability, and genuine dive-watch heritage.
