OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M ref. 210.30.44.51.06.001 is a chronograph with a 44 mm steel case, 17.2 mm thick and 52.8 mm lug to lug, fitted with a unidirectional rotating bezel. A domed sapphire crystal with antireflective treatment on both sides covers the grey dial. The self-winding calibre 9900 drives the watch, a column-wheel chronograph with Co-Axial escapement and silicon balance spring, certified as a Master Chronometer and resistant to magnetic fields up to 15,000 gauss, with a power reserve of 60 hours. Beyond the chronograph, the watch adds a date display, small seconds and a transparent caseback. It comes on a steel bracelet with a foldover clasp that has comfort setting and diver extension. The screw-down crown and helium valve support the case's 300 metre water resistance.
