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.

Wolbrook Skindiver Automatic

Owners widely praise the Wolbrook Skindiver Automatic 38mm for its vintage-inspired design, compact 38mm size, and tool-like aesthetic, offering good value for its price. The watch features ridiculously bright and long-lasting lume, a clean dial, and a Miyota 9039 no-date movement. Some owners find the push-pull crown a drawback, while others note the clasp and some bracelet links can feel sharp. Opinions are split on the bracelet design, with some finding it confusing and others praising its articulation and micro-adjustments. One owner found the 40mm case felt larger than expected. Overall, owners rate the Wolbrook Skindiver Automatic 38mm highly for its vintage aesthetic and tool-watch appeal at a reasonable price.
