The first Seamaster Diver 300M appeared in 1993, revolutionising the field of underwater watches. Today, OMEGA continues the story with a range of modern men’s timepieces featuring new materials and innovative technologies. These luxury Swiss wristwatches are offered in two different sizes, including 42 mm and 43.5 mm, and can be chosen in stainless steel, ceramic, or with touches of 18K gold. Each design exemplifies the Seamaster Diver 300M spirit, with its waved dials, helium escape valve and skeletonised hands. They also deliver extraordinary standards of water‑resistance, as well as dial colours ranging from black or white, to blue and PVD chrome. Around the wrist, these sporty OMEGA dive watches can be worn on rubber straps, metal bracelets or NATO straps, while each one is driven by a Co‑Axial Master Chronometer Calibre, offering the industry’s highest certified standard of precision, performance and magnetic resistance.
