About this watch

The Omega Seamaster Planet Ocean 600M Co-Axial stands out as an epitome of craftsmanship and functionality. Its striking appearance features a stunning black dial, luminous hands, and indexes. The gem-set bezel adds elegance, making it suitable for both casual outings and formal events. Measuring 45.5 mm in diameter, the high-quality stainless steel case ensures durability and longevity. The round shape feels comfortable on the wrist, and the open case back provides a glimpse into the intricate mechanics of the watch—a beautiful sight for any watch enthusiast. At the core of the Seamaster Planet Ocean 600M is the Omega caliber 8500, an automatic movement featuring two barrels, providing a generous power reserve of up to 60 hours. The frequency of 25,200 vibrations per hour ensures that this watch runs smoothly and accurately, making it a chronometer certified by COSC (Contrôle Officiel Suisse des Chronomètres). One of the standout features of the caliber 8500 is its Co-Axial escapement, reducing friction among components, leading to improved accuracy and longevity. The Seamaster Planet Ocean 600M boasts an impressive water resistance of 600 meters, making it a reliable companion for any underwater adventure. The unidirectional rotating bezel ensures that you can keep track of your time underwater easily.
