The case stands 10.1 mm thick with a lug-to-lug span of 39.38 mm, and a domed sapphire crystal with anti-reflective treatment covers the silver dial. Inside is the self-winding calibre 8800, a Master Chronometer certified movement with Co-Axial escapement and a silicon balance spring, resistant to magnetic fields up to 15,000 gauss. Power reserve runs to 55 hours. The date function sits on the dial, and a sapphire display back shows the movement's Geneva waves in arabesque finish. A steel and Sedna gold bracelet closes with a butterfly clasp. Omega rates the case to 30 metres.
