OMEGA Seamaster Aqua Terra 150M

Omega's Seamaster Aqua Terra 150M, reference 220.20.30.20.02.001, measures 30 mm across in steel and Moonshine gold. The case stands 10.55 mm thick with a lug-to-lug of 36.5 mm, and the silver dial sits under a domed sapphire crystal with antireflective treatment on both sides. Inside is the self-winding calibre 8750, a Master Chronometer movement certified by METAS with a silicon balance spring and 48 hours of power reserve. It resists magnetic fields to 15,000 gauss, a genuine strength for a chronometer of this size. Date sits at 6 o'clock, and a transparent caseback shows the rhodium-plated rotor and Geneva waves finish. The steel and gold bracelet closes with a butterfly clasp fitted with a comfort setting. Rated to 15 bar, the case holds up to 150 metres of water resistance.
