This 42 mm Seamaster Diver 300M is crafted from stainless steel and features a polished blue ceramic dial with laser-engraved waves, complemented by a matching blue ceramic bezel with a white enamel diving scale. Skeleton hands and raised rhodium-plated indexes filled with Super-LumiNova ensure excellent legibility, while the conical helium escape valve highlights its professional-grade diving capability. Powered by the OMEGA Master Chronometer Calibre 8800 and presented on a sporty blue rubber strap, this timepiece combines precision, durability, and iconic Seamaster style, with the movement visible through the sapphire-crystal wave-edged caseback.
