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.

Longines HYDROCONQUEST GMT

Owners widely praise the Longines HYDROCONQUEST GMT for its excellent finishing, smooth winding action, and overall value, with some finding its build quality and colorways superior to higher-priced competitors. Reviewers and owners alike note its robustness as a traveler's dive watch with a true GMT movement. Some owners find the round markers at 6 and 9 disrupt dial symmetry, and the GMT hour markers are described as tiny and difficult to read. The date wheel can be mismatched on certain dial colors, and the bracelet clasp is noted as sharp by one reviewer. While some owners wish for a smaller case size, others find the 41mm comfortable. The bezel action is flagged as having bounce-back by one owner, though the brushed finish effectively hides wear. Overall, owners and reviewers rate the Longines HYDROCONQUEST GMT highly for its robust build and excellent value proposition.
