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.

Tornek-Rayville TR-660 Sapphire Non-date

Owners widely praise the Tornek-Rayville TR-660 for its quality, good timekeeping, and suitability as a military diver reissue. The 40mm bead-blasted 316L stainless steel case, sapphire bezel inlay, and Arclite Super LumiNova are noted features, powered by a Japanese TMI NH38 automatic movement and water-resistant to 20 ATMs. Some owners suggest alternatives due to availability issues with the small-batch releases. Overall, owners rate the Tornek-Rayville TR-660 highly for its faithful reissue design and quality build at its price point.
