About this watch

The Omega Seamaster Planet Ocean 600M Co-Axial 2900.50.81 is a masterpiece of Swiss craftsmanship, embodying the essence of diving heritage and luxury. This watch boasts an impressive water resistance of up to 600 meters, making it perfect for professional divers and those who enjoy aquatic sports. The bold design features a black dial with mixed indexes, creating a striking contrast against the stainless steel case. The rotating bezel, marked from 0 to 60, allows divers to track their immersion time accurately.

With its Co-Axial escapement, this movement reduces friction between parts and enhances precision. The Seamaster Planet Ocean is a certified chronometer, undergoing rigorous testing to ensure its accuracy. Whether you're diving into the ocean or attending a formal event, this watch adapts seamlessly to any occasion. Its simple yet effective layout makes reading the time a breeze, while the luminous hands ensure readability in low-light conditions.
