About this watch

The Omega Seamaster 300 Master Co-Axial Titanium exudes sophistication with its stunning blue dial, crafted from robust titanium that offers exceptional durability. The 41 mm diameter strikes a balance between presence and wearability, while the rotating bezel adds to the watch's diver heritage. Coupled with a scratch-resistant sapphire crystal glass, this timepiece is built to withstand underwater exploration. At the core of the Seamaster 300 lies the impressive Omega caliber 8400 movement, engineered for precision and durability with a Co-Axial escapement. This self-winding movement offers greater precision and stability over time, resistant to magnetic fields greater than 15,000 gauss. The watch's water resistance rating of 300 meters makes it a true dive watch, perfect for tracking time underwater. With its comfortable strap and adjustable fit, this luxury dive watch is designed to accompany you on your next underwater adventure.
