What people say

Owners + reviewers, side by side

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

Hamilton Jazzmaster Open Heart Auto

The Hamilton Jazzmaster Open Heart Auto is noted for its dressy yet versatile design, featuring striking gradient dials and intricately shaped cutouts that reveal the H-10 movement. It boasts an 80-hour power reserve and Nivachron hairspring. The watch is available in 36mm, 40mm, or 42mm stainless steel cases. On balance, the Hamilton Jazzmaster Open Heart Auto is appreciated for its visually engaging dial and movement display at its price point.

From video reviewers

The smoked dial's precision cutouts offer a captivating view of the automatic movement. Legibility is compromised by the open-heart design.

Maen Manhattan 40

Owners appreciate the Maen Manhattan 40's thin case and unique dial, with some finding its proportions too large for smaller wrists. One owner noted a snagging crown and difficult winding action. Accuracy figures vary, with one owner reporting +18s/d to +24s/d on the 37mm version, while another owner of the 40mm model did not specify accuracy. On balance, owners and reviewers find the Maen Manhattan 40 to be a good value, with its thinness and dial finishing being key strengths.
