About This Reference


The modern Seamaster Diver 300M was relaunched in 2018 with a ground-up redesign that elevated every element of the collection, and the 210.22.42.20.01.002 sits among its most striking configurations. The 42mm stainless steel case is paired with an 18K Sedna™ gold unidirectional rotating bezel fitted with a black ceramic insert and Omega's Liquidmetal™ diving scale — a material bond that ensures the markings remain crisp over decades of wear. The black polished ceramic dial features laser-engraved ocean waves, Sedna gold skeleton hands and raised indexes filled with white Super-LumiNova, and a date window at 6 o'clock. The conical helium escape valve at 10 o'clock reinforces its professional dive credentials, and the calibre 8800 visible through the wave-edged sapphire caseback delivers Master Chronometer precision with magnetic resistance exceeding 15,000 gauss.
