Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
The Zelos GT is lauded for its value and bold design, with owners highlighting the cool power reserve meter and superb 3-point micro-adjust bracelet. Some owners find the case and lugs could hug the wrist better, and the bracelet is noted as being quite long, requiring significant link removal for a 7.1-inch wrist. The dark green dial, while inspired by Lamborghini, is described as appearing mostly black. Overall, owners rate the Zelos GT highly for its value and the quality of its bracelet at the price point.
