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.

Maen Grand Tonneau Ultra Thin

Owners widely report the Maen Grand Tonneau Ultra Thin features a La Joux-Perret D101 manual-wind movement and a double-layer enamel dial. Some owners criticize the bracelet design and find the dial too small and lacking indices. One owner describes the Maen Grand Tonneau Ultra Thin as "hideous with a good movement." On balance, owners are divided on the Maen Grand Tonneau Ultra Thin, with some appreciating its movement and dial while others find its design unappealing.
