About this watch

The Omega Seamaster Planet Ocean 600M Co-Axial 37.5 is a masterpiece that resonates with both watch enthusiasts and casual wearers alike. Its sleek design and robust features make it the perfect companion for underwater adventures and high-class gatherings. The black dial against the stainless steel case creates a stunning contrast, making it look sleek yet bold. The round shape is classic and versatile, allowing it to seamlessly transition from casual outings to formal occasions. At the heart of this timepiece is the Omega caliber 8520, an automatic movement that's a chronometer, meaning it's been tested for precision and accuracy. With a 50-hour power reserve and a frequency of 25,200 vibrations per hour, you can trust that the Seamaster will keep ticking reliably. The rotating bezel marked from 0 to 60 is a crucial feature for divers, allowing you to track elapsed time underwater. Omega has a reputation for quality, and this model is no exception, with a sapphire crystal that's resistant to scratches and an open case back showcasing the craftsmanship of Omega.
