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.

CWC 1980 RN Divers Automatic Re-Issue Watch

The CWC 1980 RN Divers Automatic Re-Issue Watch is widely praised for its faithful recreation of vintage details, including its dial layout with markers touching the chapter ring and pointed crown guards. Owners and reviewers note its reasonable size and the original minute hand design. However, the lume is a point of contention: some find the "faux patina" tint too gold and glossy, while others specifically criticize the mismatched lume color between hands and hour markers, with the hour marker lume described as overly shiny and convex. On balance, the CWC 1980 RN Divers Automatic Re-Issue Watch is highly regarded for its authentic vintage aesthetic and wearability, despite mixed opinions on the lume application.

From video reviewers

The watch's accurate movement is a notable strength. A potential weakness is its relatively high price point. Reviewers disagree on the watch's water-resistance, with one reviewer suggesting it could be improved and the other not mentioning any issues with water-resistance.
