Latest upgraded version Omega Seamaster Planet Ocean 42mm co-axial Master Chronometer watch. Model number: 30.42.20.01.01.001. Features a brushed stainless steel case with partial polishing, and a black bezel adorned with white enamel diving markers that are resistant to wear and fading. The ratcheted countdown bezel rotates counterclockwise in a single direction. It has a domed sapphire crystal with anti-reflective coating, and a polished black dial featuring a laser-engraved wave pattern. A date window is located at 6 o'clock, with skeleton hands and relief hour markers treated with rhodium and coated with Super LumiNova luminescent material. The dual-color luminescence includes blue-green for the hour and green for the minute hand, integrated with a green luminescent dot on the bezel for diving oxygen countdown. The watch has multiple waterproof features and a screw-down crown, making it suitable for actual diving. There is a conical helium escape valve and a wave-edge designed transparent case back that showcases the intricate movement. It is powered by the imported Seiko Caliber 8800 movement. The brushed stainless steel bracelet features a similar two-side screw removal method as the genuine model and an independently fixed rod design in the middle. It comes with a folding clasp with double push buttons and a pressure-adjustable extension, allowing it to be worn over diving suits during deep-sea activities. Reposting is welcome.
