About this watch

The Omega Seamaster Diver 300M Master Co-Axial 42 is a masterpiece of engineering and design, blending elegance with robust functionality. Its stunning summer blue dial features a gradient finish, adding depth and character to the watch face. The case is crafted from stainless steel and ceramic, built to withstand underwater adventures. A rotating bezel allows for accurate dive time tracking, and a water resistance of up to 300 meters ensures it can endure ocean depths. At its heart lies the Omega caliber 8800 movement, a marvel of engineering with Co-Axial escapement, reducing friction and enhancing longevity and accuracy. Rigorously tested according to Master Chronometer certification, this watch is resistant to magnetic fields reaching 15,000 gauss and has a power reserve of 55 hours. The Seamaster Diver 300M comes with a stainless steel bracelet that complements the watch's aesthetics while providing a comfortable fit.
