The Omega Seamaster 300 series is a popular bestseller. With a diameter of 42mm, it features a domed double-sided anti-reflective sapphire crystal. The dial is made of polished ceramic and laser-engraved with wave patterns. The open hands and raised hour markers are rhodium-plated and coated with Super-LumiNova for superior night visibility. The bezel is also made of ceramic and decorated with enamel diving scales. It is powered by the 8800 coaxial movement, with the entire movement decorated with Geneva waves, ceramic ball bearings, and a bi-directional automatic winding system. The silicon hairspring and free-sprung balance wheel provide 15,000 gauss anti-magnetic protection. The power reserve is 60 hours. Most importantly, it is equipped with the third-generation coaxial escapement. The black balance wheel is visible to the naked eye and is consistent with the genuine product. The clasp has a fine adjustment function. This watch inherits the glorious marine legend and combines Omega’s technological innovation and design concepts to present a new masterpiece.
