Aqua Terra 150M Seamaster Steel Master Chronometer 220.30.43.22.10.001

This 43 mm Worldtimer has a case in stainless steel with integrated matching bracelet and butterfly clasp. At the centre of the sun-brushed green dial, framed by a polished-brushed green ceramic bezel, OMEGA has produced a vision of Earth, viewed from above the North Pole, by laser-ablating continents and colours on a grade 5 titanium surface. Circling the topographic map is a 24-hour indication under hesalite glass, divided into night and day sections. OMEGA’s home city of Bienne Switzerland is among the many global destinations circling around the dial and its outer ring. All place names, with the exception of the British capital are coloured yellow gold. London is in red to highlight Greenwich Mean Time, now more formally known as Universal Time Coordinated (UTC). World times are measured by hands and indexes in 18K Moonshine™ Gold. OMEGA’s Co-Axial Master Chronometer Calibre 8938 provides the power.
