Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners praise the Breitling Super Chronomat Automatic 38 for its unique 38mm size, beautiful dial, and highly polished case and bracelet. One owner notes a 42-hour power reserve and a caution against setting the time backward between 8 AM and 3 PM. Another owner experienced accuracy and power reserve issues requiring service. Overall, owners rate the Breitling Super Chronomat Automatic 38 highly for its distinctive size and finishing, despite some reports of timekeeping inconsistencies.
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.
