OMEGA Seamaster Aqua Terra 150M

The Omega Seamaster Aqua Terra 150M 220.55.38.20.99.003 has a 38 mm case in white gold. The case measures 12.46 mm thick with a lug-to-lug span of 45.1 mm. Inside is the self-winding calibre 8807, a Master Chronometer movement with a Co-Axial escapement and a free sprung-balance, certified by METAS and resistant to magnetic fields up to 15,000 gauss. It runs with a power reserve of 55 hours. A domed sapphire crystal with anti-reflective treatment on both sides covers the silver dial, and the caseback is transparent to show the movement. The watch is set with diamonds and fitted on a white gold bracelet with a butterfly clasp. The screw-down construction keeps the Aqua Terra water resistant to 150 metres.
