What people say

Owners + reviewers, side by side

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

Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322

Owners widely praise the Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322 for its gorgeous, color-popping black mother-of-pearl dial and good case finishing, with some appreciating its distinct bead-blasted case and H-link bracelet. The $375 price is noted as a strong value for a true mother-of-pearl watch. However, opinions are divided on the dial text font and the Islander logo, with some finding them unattractive and others seeing them as minor issues on an otherwise appealing tool watch. On balance, owners rate the Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322 highly for its striking mother-of-pearl dial and value proposition.

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.
