What people say

Owners + reviewers, side by side

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

Hamilton Khaki Aviation Day Date Auto

Owners and reviewers widely praise the Hamilton Khaki Aviation Day Date Auto for its handsome, legible dial with raised indices and day/date complications, and its versatile, modern pilot watch design. The fully brushed case and good lume are noted strengths, with one owner finding it wears comfortably on a NATO strap. The H-10 caliber offers an 80-hour power reserve, though its decoration and regulation are less refined. Some find the 42mm size large and the skeletonized hour hand tip visually unappealing, while others note the AR coating is decent but not exceptional. Overall, owners and reviewers rate the Hamilton Khaki Aviation Day Date Auto highly for its practical design and value at its price point.

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.
