Pre-owned Omega Seamaster Diver 300M ref 212.30.44.52.01.001 brings together everything collectors love about the Seamaster: robust engineering, precision timekeeping, and unmistakable style. The 44mm stainless steel case houses a matte black dial with crisp chronograph registers, a red 24-hour scale, and a matching red GMT hand that lets you track a second time zone with ease. True to its professional roots, it features a black ceramic unidirectional bezel, helium escape valve, and 300 meters of water resistance, hallmarks of Omega’s legendary dive watch lineage. Inside the case ticks the Co-Axial calibre 3603 with a handy 52-hour power reserve. Paired with a stainless steel bracelet and secure folding clasp, this Diver 300M GMT Chronograph feels equal parts instrument and statement piece. Shop OMEGA Seamaster Collection
