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 37 IFL Edition

Maen Manhattan is praised for its value at $1,499, featuring a slim 9.3mm case, 100m water resistance, and a comfortable integrated bracelet. Owners highlight its simple design and automatic movement.

From video reviewers

The hand-painted dial is a standout feature. The lume brightness is not particularly bright. Reviewers disagree on the value proposition at the $1,499 price point.
