For sale is this beautiful Omega Seamaster Diver 300M in the “Summer Blue” colorway, part of Omega’s 75th Anniversary collection. This variant stands out from the standard 300M lineup with a deeper gradient dial, a matching blue ceramic bezel, and an overall color profile that’s unique without drifting into gimmick territory. The dial shifts from light to dark blue depending on the angle, giving the laser-cut wave pattern a lot more depth than the standard black or blue models. The matching “Summer Blue” Super-LumiNova is a subtle upgrade as well—cooler in tone and more cohesive with the bezel and dial. This model retains the classic 300M case design: 42mm, helium escape valve, scalloped ceramic bezel, and the sharply brushed/polished finishing Omega is known for. It’s powered by the Co-Axial Master Chronometer Calibre 8800, anti-magnetic to 15,000 gauss with a 55-hour power reserve and METAS certification. If you’ve handled prior 300Ms, this one feels familiar but noticeably more refined in its color execution. It’s a modern diver that doesn’t look like every other blue dive watch on the market.
