Omega Seamaster Planet Ocean 600M Co-Axial 45.5 Mécanique 24 Sapphires

About this watch

The Omega Seamaster Planet Ocean 2902.50.38 is a masterclass in luxury watchmaking, perfectly blending style and substance. This stunning timepiece features a striking blue mother of pearl dial, surrounded by a gem-set bezel that adds a touch of sophistication. The bold, round shape and 45.5mm diameter make it a statement piece that's sure to turn heads. Whether you're diving deep or dressing up, this watch seamlessly transitions from day to night. At its heart is the Omega Caliber 2500, an automatic movement with co-axial escapement that reduces friction and increases accuracy. With a power reserve of 48 hours and water resistance of 600 meters, it's built for serious diving adventures. The combination of white gold and stainless steel adds durability and luxury, while the sapphire glass ensures scratch-resistance. This watch is not just a timepiece - it's an experience, a legacy, and a piece of art that you can cherish for a lifetime.
