The Aqua Terra Worldtimer in its 43mm stainless steel case centres on one of the more striking dials in the current Omega catalogue: a sun-brushed green field with a laser-ablated topographic rendering of Earth — viewed from above the North Pole — executed on a grade 5 titanium surface. A 24-hour disc rings the globe, dividing night from day, while the outer chapter lists world cities in Moonshine Gold with London picked out in red to mark UTC.

The polished-brushed green ceramic bezel frames the whole arrangement, and 18K Moonshine Gold hands and indices carry the time. Calibre 8938 — a Co-Axial Master Chronometer rated to 15,000 gauss and delivering 60 hours of power reserve — drives the GMT/Worldtimer complication. This reference is fitted with an integrated stainless steel bracelet secured by a butterfly clasp, adding around 40g over the rubber strap variant; the result is a more substantial, cohesive package that wears as a unified steel object from case to wrist.
