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 Auto

The Hamilton Jazzmaster Auto is widely praised for its excellent value, clean and uncomplicated design suitable for various occasions, and comfortable wearability, with a 40mm or 42mm case size that is considered unobtrusive. Reviewers highlight its refined H-21 movement, which offers a 60-hour power reserve, and distinctive sunray dials. Overall, owners and reviewers rate the Hamilton Jazzmaster Auto highly for its impressive balance of contemporary style and traditional watchmaking at its price point.

Spinnaker Croft 39 GMT

Owners praise the Spinnaker Croft 39 GMT for its colorful design, NH34 GMT movement, and reasonable price, noting high-standard manufacturing on the case, bezel, and bracelet. One owner finds the 43mm case and 51mm lug-to-lug dimensions too large for the design, preferring a 39-40mm case size. A potential issue with the lume was noted by one user. On balance, owners value the Spinnaker Croft 39 GMT for its attractive design and build quality at its price point, though sizing is a point of contention for some.
