The Aqua Terra Worldtimer (ref. 220.10.43.22.03.001) is Omega's GMT-and-worldtime dress-sport watch, 43mm steel, blue lacquered dial with a hand-painted globe and 24-city ring, the caliber 8938 Master Chronometer. It is the modern travel watch that does the most with the least dial real estate: read local time on the hour/minute hands, read GMT-offset on the city ring, set local timezone with the crown without disturbing the running time.
Omega launched the Aqua Terra in 2002 as the dressier Seamaster sub-line, 150m water resistance, teak-pattern dial, designed for the wearer who wanted a Seamaster look without the rotating bezel. The Worldtimer variant arrived in 2017, with the caliber 8938 (Master Chronometer, METAS-certified, ±0/+5 seconds-per-day, 15,000-gauss-resistant). The dial features a hand-painted globe with continental outlines around a central worldtime disc; the cities ring shows 24 timezones in 24-hour format.
Steel and rose-gold case options; blue and silver dial variants. The 43mm size is the canonical reference.
Common things to check: dial freshness (the hand-painted globe and applied 'OMEGA' wordmark are difficult to service-restore, refinished dials are visible on close inspection); worldtime function (the city ring should rotate cleanly and the local-hour-set should disengage the GMT chain, verify the worldtime mechanism engages and releases without binding); caliber 8938 (Master Chronometer certification means the movement holds tolerance for 8-10 years, but the worldtime module adds wear surfaces); bracelet (the brushed-link Aqua Terra bracelet ships factory; aftermarket replacements are common and acceptable but should be priced accordingly); the gold-on-steel variants trade at substantially different prices than steel-only.
