Omega's Seamaster Diver 300M (Paris 2024), reference 522.21.42.20.04.001, is a dive watch with a 42 mm steel case. The case measures 13.72 mm thick with a lug-to-lug of 50 mm, and a unidirectional rotating bezel surrounds the white dial. A self-winding Omega calibre 8800 drives the watch, certified as a Master Chronometer and resistant to magnetic fields up to 15,000 gauss, with a power reserve of 55 hours. The dial sits under a domed sapphire crystal with anti-reflective treatment on both sides. A date function and helium valve accompany the screw-down crown, useful for saturation diving. The watch is fitted on a steel bracelet with a foldover clasp that has a comfort setting and diver extension. The clasp itself is built to the case's 300 metre water resistance rating.
