OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M ref. 210.60.44.51.03.001 is a chronograph with a 44 mm titanium case. It measures 17.4 mm thick with a lug-to-lug of 52.8 mm, finished in titanium, tantalum and Sedna gold. A domed sapphire crystal with antireflective treatment covers the blue 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 fields up to 15,000 gauss. It offers 60 hours of power reserve and adds a time zone function alongside the date and small seconds. A unidirectional rotating bezel surrounds the dial, and a display back shows the movement. The bracelet, in matching titanium, tantalum and Sedna gold, closes with a foldover clasp, and the case holds a 300 metre rating.
