What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Marathon GPQ-D (Officer's Quartz with Date) Field Watch

Marathon GPQ-D (Officer's Quartz with Date) Field Watch owners praise its tritium tubes, Mil-spec designation, and scratch-resistant case finish, with some finding the 36mm size practical for field use. However, some owners criticize its perceived overpriced nature, thick case, and squared-off lugs, while others point to the composite case material, 30m water resistance, and unbranded movement as drawbacks. On balance, owners are divided on the Marathon GPQ-D (Officer's Quartz with Date) Field Watch, with opinions split on its value and design features.

Longines LEGEND DIVER

Owners widely praise the Longines LEGEND DIVER for its faithful retro design, often calling it one of the best vintage reissues, with the 39mm variant lauded for its perfect size and the 42mm for its versatility. The watch is consistently noted as ISO 6425 compliant and powered by the COSC-certified L888.6 movement with a 72-hour power reserve. Reviewers highlight its sophisticated look, clean no-date dial, and the well-made beads-of-rice bracelet, though some owners find the polished center links or overall polished finish dressier than expected for a diver. Owners are split on the 39mm's bracelet, with one finding it too "blingy" and another praising its comfort. The 42mm version's 50mm lug-to-lug measurement is considered long by some, while others find it comfortable. One owner of the 42mm model reported a scratched hour hand after 15 years, and another noted the original leather strap's poor quality.

From video reviewers

The Longines LEGEND DIVER features a unique blend of vintage design and modern functionality, with 300 meters of water resistance and a 72-hour power reserve. The watch's historical significance and aesthetic appeal are notable strengths. The 7-link bracelet is also a notable feature, although its quality and comfort are not explicitly discussed.
