OMEGA Seamaster Aqua Terra Shades

Omega's Seamaster Aqua Terra Shades, reference 220.10.38.20.03.003, 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 Atlantic blue 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 by METAS and resistant to magnetic fields up to 15,000 gauss, with a power reserve of 55 hours. The date sits alongside a screw-down crown, and a sapphire display back shows the movement. Steel links form the bracelet, closed by a foldover butterfly clasp. Water resistance reaches 150 metres, backed by that screw-down crown.
