What people say

Owners + reviewers, side by side

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

Bremont MBII

The Bremont MBII is praised for its striking, high-tech pilot's watch aesthetic, reassuring heft, and quality feel, featuring an anti-shock system and customizable barrel. Owners note its condition can be excellent with minor hairlines, and it is presented with all original boxes and papers. A drawback cited is its 38-hour power reserve compared to newer movements. Overall, owners and reviewers consider the Bremont MBII affordable and a good representation of the brand.

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.
