What people say

Owners + reviewers, side by side

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

Beaufort Aerotimer

Owners widely praise the Beaufort Aerotimer for its handsome, high-contrast salmon dial and museum-quality finishing, creating a sharp dress field watch with excellent legibility and a crisp California dial. One owner notes the power reserve is closer to 30-34 hours than advertised and finds the 11.45mm thickness slightly noticeable, while another would change the strap. Lume on the 3 and 9 o'clock markers is reportedly poor. Overall, owners rate the Beaufort Aerotimer highly for its vintage style and beautiful craftsmanship at its price point.

Tissot Gentleman Open Heart

Owners widely praise the Tissot Gentleman Open Heart for its versatile dressy-sporty aesthetic and elegant sunburst dial finish, with one owner preferring its less shiny blue dial compared to other versions. The watch offers excellent fit and bracelet adjustability, and its modified Powermatic 80 movement achieves COSC-level accuracy of -3 to +5 seconds/day, though the seconds hand movement is slightly less smooth at 6 movements per second. However, one owner reported the watch arrived non-functional, requiring a return due to an inoperable movement. On balance, owners rate the Tissot Gentleman Open Heart highly for its aesthetic appeal and accurate timekeeping, despite a reported instance of a faulty movement.
