Omega Seamaster Aqua Terra Worldtimer 220.30.43.22.10.001 43 mm Steel Green Dial Watch

A polished and brushed green ceramic bezel surrounds the sun-brushed green dial of this 43 mm Seamaster Aqua Terra Worldtimer in stainless steel. At its centre, Earth is shown from above the North Pole, with continents and colours laser-ablated on grade 5 titanium, ringed by a 24-hour scale split into day and night.

The surrounding destinations, OMEGA's home city of Bienne among them, are coloured in yellow gold, with London alone in red to mark Greenwich Mean Time, or UTC. Hands and indexes are 18K Moonshine™ gold. The METAS-certified Co-Axial Master Chronometer calibre 8938 drives the GMT and worldtimer functions, with a 60-hour power reserve. The 14.12 mm case, on an integrated bracelet with butterfly clasp, is water resistant to 150 metres.
