Pre-owned Omega Seamaster Diver 300M ref 210.20.42.20.01.002 (2026) brings a touch of luxury to one of the most iconic modern dive watches. Made from stainless steel and 18k yellow gold, this 42mm model retains all the professional-grade functionality that’s defined the Seamaster line since 1993, but with an elevated, two-tone aesthetic. The polished black ceramic dial is laser-engraved with the collection’s signature wave motif, complemented by a matching black ceramic bezel with a Ceragold™ diving scale. The skeletonized hands and applied hour markers, both in yellow gold and filled with Super-LumiNova, provide exceptional legibility underwater or after dark. A date window sits neatly at 6 o’clock. Powered by Omega’s Master Chronometer caliber 8800, visible through the sapphire caseback, this Seamaster pairs precision with high style. Shop OMEGA Seamaster Collection
