OMEGA Seamaster Aqua Terra Shades

The Omega Seamaster Aqua Terra Shades, reference 220.20.38.20.02.002, has a 38 mm case in steel and Moonshine gold. It measures 12.36 mm thick with a lug-to-lug span of 45.1 mm, and the domed sapphire crystal carries antireflective treatment on both sides. Inside is the self-winding calibre 8800, a Co-Axial escapement movement certified as a Master Chronometer and resistant to magnetic fields up to 15,000 gauss. It runs on a free sprung-balance with a silicon balance spring and stores 55 hours of power reserve. The silver dial shows the date, and a transparent caseback lets the movement be seen. A butterfly clasp closes the matching steel and gold bracelet. Omega rates the case to 150 metres.
