What people say

Owners + reviewers, side by side

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

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.

Yema Superman Worldtime GMT

Owners widely praise the Yema Superman Worldtime GMT for its premium feel, unique bezel-lock mechanism, and attractive domed crystal. Some owners note the aluminum bezel insert is less desirable than ceramic and report the bracelet clasp can be stiff or difficult to open. Inconsistent quality control and poor customer service have been flagged by some owners. On balance, owners value the Yema Superman Worldtime GMT for its distinctive features and comfortable wearability.

From video reviewers

The "Coke" bezel and maxi dial are attractive design elements. The in-house automatic GMT movement is a French alternative to pricier GMTs.
