Omega Seamaster Diver 300M Master Co-Axial 42 Stainless Steel / Black / NATO Ref. 210.32.42.20.01.005

The OMEGA Seamaster Diver 300M 210.32.42.20.01.005, introduced in 2025 as part of the modern Diver 300M lineup that traces its origins back to 1993, represents the collection’s contemporary interpretation of a professional dive watch in stainless steel. This reference combines established Seamaster design codes with updated materials and technical standards. The 42 mm case is crafted from stainless steel and fitted with a black oxalic anodized aluminium bezel ring featuring a diving scale filled with white Super-LumiNova. Water resistance is rated to 300 metres, and the case is protected by a domed sapphire crystal with anti-reflective treatment on the inside. The dial is produced in black aluminium and laser-engraved with the Seamaster Diver 300M’s signature wave pattern. Skeletonised hands and applied hour markers are rhodium plated and filled with white Super-LumiNova, while the remaining dial markings, including the OMEGA logo and inscriptions, are transferred in white, maintaining a high-contrast, utilitarian appearance. The watch is powered by the OMEGA Co-Axial Master Chronometer Calibre 8806, a self-winding movement certified for precision, magnetic resistance up to 15,000 gauss, and a power reserve of approximately 55 hours. The movement is visible through a sapphire-crystal caseback. This configuration is delivered on a black and white striped NATO strap made from polyester fabric, fitted with polished stainless steel loops and a signed buckle, reinforcing the model’s functional and tool-oriented character within the Seamaster Diver 300M collection.
