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.
