Omega 210.90.42.20.01.003 description
The Omega Seamaster Diver 300M 210.90.42.20.01.003 debuted in 2025 as part of the modern Diver 300M collection, continuing a line that has been in continuous production since its original introduction in 1993.
The case measures 42 mm in diameter and is manufactured from OMEGA’s proprietary Bronze Gold alloy. This material was developed to provide a stable bronze composition suitable for direct skin contact, combining noble metals including 37.5% gold, palladium, and silver. The alloy offers enhanced corrosion resistance and develops a gradual, controlled patina over time without verdigris oxidation. The case is paired with a burgundy oxalic anodised aluminium bezel ring, fitted with a diving scale filled with vintage Super-LumiNova. A domed sapphire crystal with internal anti-reflective treatment protects the dial, while water resistance is rated to 300 metres. Lug-to-lug length measures 49.7 mm, with a total thickness of 13.8 mm.
The dial is produced in sandblasted black aluminium. It features PVD 18K Bronze Gold hands and blackened hour markers, all filled with vintage Super-LumiNova for low-light legibility. Additional dial markings, including the OMEGA logo, are transferred in light brown, reinforcing the warm tonal palette of the case and bezel.
The watch is presented on a brushed Bronze Gold mesh bracelet with clasp, visually integrated with the case material. Powering the watch is the self-winding Co-Axial Master Chronometer calibre 8806. The movement offers a power reserve of approximately 55 hours and meets METAS certification standards for precision, magnetic resistance, and water resistance. It is visible through the sapphire crystal caseback.
