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 Acrylic Non-date

The Tornek-Rayville TR-660 Acrylic Non-date is a 40mm bead-blasted stainless steel watch with a utilitarian matte black dial and a moisture detector, measuring 14.7mm thick and 48.5mm lug-to-lug, featuring a subtly domed, AR-coated crystal. One owner notes a preference for a different watch's bezel-locking mechanism but appreciates the TR-660's 20mm lug size. Another owner reports damage to the case and bezel, though it includes unused and worn straps. On balance, owners find the Tornek-Rayville TR-660 Acrylic Non-date to have a timeless design that remains appealing.
