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.

Seiko Prospex SPEEDTIMER

Owners widely praise the Seiko Prospex SPEEDTIMER's design, with specific mentions of its beautiful ice blue sundial and compact 39mm case size, which some note wears smaller than its specifications due to a short lug-to-lug distance. Reviewers highlight its racing-inspired aesthetic and versatility, with one owner finding the 39mm solar model a sturdy and reliable everyday watch with 100m water resistance. However, some owners question the value proposition, citing the $700 price for a solar quartz model and a thickness of 13mm, while others expressed a preference for automatic movements. On balance, owners and reviewers appreciate the Seiko Prospex SPEEDTIMER's attractive vintage-inspired design and compact wearability, though some debate its value and thickness for a solar quartz chronograph.
