OMEGA Seamaster Aqua Terra Shades

The Omega Seamaster Aqua Terra Shades, reference 220.20.34.20.10.002, measures 34 mm in steel and Moonshine gold. The case stands 11.98 mm thick with a lug-to-lug of 40.5 mm, and the green dial sits under a domed sapphire crystal with antireflective treatment on both sides. Inside is the self-winding calibre 8800, a Master Chronometer movement with a Co-Axial escapement resistant to magnetic fields up to 15,000 gauss, running on a free sprung-balance with a silicon spring and offering 55 hours of power reserve. A date function is set into the dial, and the sapphire caseback is left open to show the movement. The bracelet, steel and Moonshine gold, closes with a foldover butterfly clasp with a comfort setting. Fifteen bar of pressure resistance keeps the case rated to 150 metres.
