Omega Seamaster 210.30.42.20.03.001

The Omega Seamaster Diver 300M watch is crafted from imported 316L stainless steel. The bezel features high-density ceramic sourced from South Korea, accented with a white enamel diving scale. The dial is also fashioned from polished ceramic and adorned with a laser-engraved wave pattern. The 42mm case boasts a refined, brushed finish.
Each link of the steel bracelet is hand-polished. This is the first version on the market to feature chamfered edges on the underside of the links—matching the original design—and the bracelet is fully interchangeable with the genuine article. The optional fluororubber strap offers a smooth, substantial feel, and its spring bars are compatible with the steel bracelet.
The sapphire crystal is produced using the Verneuil process (also known as the flame-fusion method). It achieves a hardness of 9 on the Mohs scale while ensuring exceptional clarity at all times.
The watch is powered by an exclusively developed, custom-made 8800-style integrated movement, which has undergone months of rigorous testing to ensure stable performance.
