What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Promaster Air GMT

The Citizen Promaster Air GMT is widely praised for its impressive in-house Cal. 9054 automatic GMT movement, excellent case fit and finish, and a high-quality bracelet for its price point. Reviewers highlight its striking anti-reflective domed sapphire crystal, legible dial with large numerals, and long-lasting lume. However, its 44.5mm dimensions are considered unfashionably large, and the case design is described as uninspired. The independent hour jumping is noted as mushy and unable to be set backward, while the unframed 3 o'clock date window and minute track on the rehaut being obscured by case shadows are also flagged as drawbacks. The watch is priced at $1,125 USD and features 200m water resistance and a 50-hour power reserve. On balance, reviewers commend the Citizen Promaster Air GMT for its strong movement and legibility at an affordable price, despite reservations about its case size and some functional aspects of the GMT hand.

Formex Stratos UTC

Owners and reviewers widely praise the Formex Stratos UTC for its user-friendly flyer GMT complication, which utilizes pushers for time-zone adjustments, and its slim 11.8mm case. The watch is noted for its intricate, hand-finished case with a multi-layer construction and excellent finishing, along with a unique two-level case design. The Dubois-Depraz module on an ETA 2892 movement is a highlight, with accuracy figures ranging from +/- 5 to +/- 7 seconds per day. However, some find the dial busy with multiple typefaces and the overall design too complex or "plug ugly," with the price near €4000 considered high by some for a newer brand. Overall, owners and reviewers rate the Formex Stratos UTC highly for its innovative GMT functionality and excellent case finishing at its price point.
