Hamilton Jazzmaster Power Reserve AutovsLongines HYDROCONQUEST GMT

The Hamilton Jazzmaster Power Reserve Auto is praised by owners and reviewers for its value and history, featuring an 80-hour power reserve caliber H-13 movement. Owners note poor lume, easily scratched polished bezels, and a mineral crystal on the movement display. One owner suggests the 80-hour power reserve is difficult to achieve without manual winding. On balance, owners and reviewers rate the Hamilton Jazzmaster Power Reserve Auto well for its value and history, despite noted drawbacks in finishing and crystal material.

Owners widely praise the Longines HYDROCONQUEST GMT for its excellent finishing, smooth winding action, and overall value, with some finding its build quality and colorways superior to higher-priced competitors. Reviewers and owners alike note its robustness as a traveler's dive watch with a true GMT movement. Some owners find the round markers at 6 and 9 disrupt dial symmetry, and the GMT hour markers are described as tiny and difficult to read. The date wheel can be mismatched on certain dial colors, and the bracelet clasp is noted as sharp by one reviewer. While some owners wish for a smaller case size, others find the 41mm comfortable. The bezel action is flagged as having bounce-back by one owner, though the brushed finish effectively hides wear. Overall, owners and reviewers rate the Longines HYDROCONQUEST GMT highly for its robust build and excellent value proposition.
