Omega Seamaster Aqua Terra 150M Master Chronometer GMT Worldtimer

The World Awaits

This 43mm Worldtimer is cased in brushed grade 2 titanium, which is framed by a brushed black ceramic bezel. It has an integrated strap in black structured rubber, with additional decorative link and clasp in brushed titanium. 

At the center of the black and grey dial, framed by a brushed black 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, 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).

To complement the matte look of the dial, OMEGA has opted for blackened hands and indexes, filled with white Super-LumiNova to emit a blue glow in the dark. Powering the watch is OMEGA’s Co-Axial Master Chronometer Calibre 8938.
