OMEGA Seamaster Aqua Terra Shades

Omega's Seamaster Aqua Terra Shades, reference 220.20.34.20.10.001, has a 34 mm case in steel and Sedna gold. The case measures 11.98 mm thick with a lug-to-lug span of 40.5 mm. A domed sapphire crystal with antireflective treatment on both sides covers the pink dial. Inside is the self-winding calibre 8800, a Co-Axial Master Chronometer movement with a silicon balance spring and 55 hours of power reserve, certified to resist magnetic fields up to 15,000 gauss. The date sits on the dial, and a transparent caseback shows the movement from behind. A steel and Sedna gold bracelet closes with a butterfly clasp. That same clasp helps keep the case sealed to 150 metres.
