Reference 233.90.41.21.03.001
About this watch
The Omega Seamaster 300 Master Co-Axial Titanium stands out as a remarkable blend of style, functionality, and innovation. This stunning timepiece is a game-changer with its use of titanium, which is lighter than stainless steel yet incredibly durable and resistant to corrosion. The deep blue dial catches the light beautifully, ensuring it stands out without being overly flashy. With a smooth finish and vibrant hue, it's reminiscent of ocean depths and aquatic adventures. At the core of this watch is the Omega caliber 8400 movement, a self-winding marvel featuring a Co-Axial escapement that enhances precision and stability while reducing friction. This means fewer maintenance needs over time, allowing you to enjoy your watch without frequent trips to the jeweler. With its impressive water resistance of 300 meters (or 1,000 feet), this watch is perfect for diving, swimming, or just splashing around at the beach. Its elegant design allows it to pair well with various outfits, making it suitable for both casual and formal occasions.
