What people say

Owners + reviewers, side by side

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

Zelos Hammerhead (Tantalum LE)

The Zelos Hammerhead (Tantalum LE) features a forged carbon dial and bezel insert with infused lume. On balance, owners and reviewers rate the Zelos Hammerhead (Tantalum LE) highly for its unique material composition and substantial feel.

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.
