OMEGA Seamaster Aqua Terra Shades

Omega's Seamaster Aqua Terra Shades, reference 220.53.34.20.10.001, comes in an 34 mm yellow gold case. The case measures 11.88 mm thick with a lug-to-lug of 40.5 mm, and the lagoon green dial sits under a domed sapphire crystal with antireflective treatment on both sides. Inside is the self-winding calibre 8801, a Master Chronometer movement with a Co-Axial escapement and resistance to magnetic fields up to 15,000 gauss. It runs on a free sprung-balance with silicon balance spring and stores 55 hours of power reserve. A date function is included, and the transparent caseback shows the movement and its arabesque Geneva waves. The watch is fitted on a green alligator leather strap with a folding clasp in yellow gold. Omega rates the case to 150 metres.
