Pre-owned Omega Seamaster Diver 300M ref 210.30.42.20.01.001 (2022) came to market just one year after Omega updated the Seamaster 300M in 2018. While it was still the SMP we all know and love, it had been updated to include modern watchmaking technologies and aesthetics. This 42mm model captures that balance perfectly, with a polished black ceramic dial laser-engraved with the signature wave pattern, a ceramic bezel with a crisp white enamel dive scale, and rhodium-plated hands and indices filled with long-lasting Super-LumiNova. It’s powered by Omega’s in-house Caliber 8800, making it the first model in the series to carry a Master Chronometer. The stainless steel bracelet, helium escape valve, and 300m depth rating keep the watch firmly rooted in the dive watch category. Shop OMEGA Seamaster Collection
