A Blog to Watch

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.
