OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M 210.90.42.20.10.001 is a dive watch with a 42 mm case combining bronze gold and titanium. The case measures 13.8 mm thick with a lug-to-lug of 49.7 mm, and the unidirectional rotating bezel frames a green dial. A screw-down crown and helium valve sit alongside the sapphire crystal, which has antireflective treatment on the inside and reveals the movement through a display back. Inside is the Omega calibre 8806, a self-winding Co-Axial Master Chronometer movement certified by METAS and resistant to magnetic fields up to 15,000 gauss, with a power reserve of 55 hours. The watch is fitted on a titanium bracelet with a titanium foldover clasp. Omega rates the case to 300 metres.
