Seamaster Aqua Terra 150M 43 mm

This 43 mm Worldtimer, cased in brushed grade 2 titanium, has an integrated strap in black structured rubber, with additional decorative link and clasp in brushed titanium.

At the centre 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 grey. 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.

Features
Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Date: The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.
GMT and Worldtimer: A GMT function means that the watch has a second hour hand which completes one full rotation in 24 hours and a 24-hour index on the dial. Particularly useful for wearers who wish to track two time zones.
Master Chronometer Certified: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Screw-in crown: Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Time zone function: Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
Transparent caseback: A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
