OMEGA Seamaster Aqua Terra Shades

Omega Seamaster Aqua Terra Shades, reference 220.10.38.20.10.002, measures 38 mm across in steel. The case stands 12.26 mm thick with a lug-to-lug span of 44.92 mm, and the bay green dial sits under a domed sapphire crystal treated against reflections on both sides. A self-winding calibre 8800 drives the watch, certified as a Master Chronometer and resistant to magnetic fields up to 15,000 gauss, with 55 hours of power reserve. The date sits on the dial, and a sapphire display back shows the movement's Geneva waves in arabesque. A screw-down crown protects the case. The steel bracelet closes with a foldover butterfly clasp. Omega rates the case to 150 metres.
