Pre-owned Omega Seamaster Diver 300M ref 210.20.42.20.03.001 (2018). Omega released the modern Seamaster Diver 300M in 2018, a major evolution of Omega’s long-running dive watch. It refined the design that first gained worldwide attention in the 1990s during the Pierce Brosnan James Bond era. This reference pairs stainless steel with 18k yellow gold for a noticeably more elevated take on the classic Diver 300M formula while still keeping the collection’s sporty DNA intact. The 42mm case is outfitted with a blue ceramic bezel featuring a Ceragold diving scale and a matching polished blue ceramic dial with laser-engraved wave patterns, a signature design cue that returned with this generation after several years away. Skeletonized hands, applied hour markers filled with white Super-LumiNova, and the conical helium escape valve all contribute to the watch’s modernized aesthetic. Powering the ref. 210.20.42.20.03.001 is Omega’s Master Chronometer caliber 8800, visible through the sapphire caseback and resistant to magnetic fields up to 15,000 gauss.
