OMEGA Seamaster Aqua Terra 150M

Omega's Seamaster Aqua Terra 150M, reference 220.20.41.21.01.001, has a 41 mm case in steel and Moonshine gold. The case measures 13.4 mm thick with a lug-to-lug span of 48 mm, and the black dial sits under a domed sapphire crystal with anti-reflective treatment on both sides. Inside is the self-winding calibre 8900, a Master Chronometer movement certified by METAS and resistant to magnetic fields up to 15,000 gauss, with 60 hours of power reserve. A date function and a display back round out the specification, and the screw-down crown adds a further layer of security. The bracelet, in matching steel and Moonshine gold, closes with a foldover butterfly clasp with a comfort setting. Water resistance reaches 150 metres.
