Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Breitling Super Chronomat Automatic 38 for its unique 38mm size, beautiful dial, and highly polished case and bracelet. Some owners, however, note the bracelet would benefit from micro-adjustment for a better fit, and a few express concern that the case feels substantial. One owner reported inconsistent power reserve, barely reaching 36 hours, and poor timekeeping that persisted after service attempts. Overall, owners appreciate the Breitling Super Chronomat Automatic 38 for its striking aesthetics and distinctive sizing, despite some concerns regarding bracelet adjustability and reported timekeeping issues.
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.
The smoked dial's precision cutouts offer a captivating view of the automatic movement. Legibility is compromised by the open-heart design.
