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.

Studio Underd0g Full Moon

Owners widely praise the Studio Underd0g Full Moon's harmonious creamy dial and its 37mm case, which fits flawlessly. The innovative sapphire disc with numerals is a highlight, though two visible screws holding it are noted as a minor aesthetic drawback. Some owners find the watch overpriced, while others see value in the upgraded Sellita movement under $1k. Lume is surprisingly good, and the included NATO strap is preferred by some over the leather. Accuracy ranges from +1/+2 seconds per day to about -6 seconds per day. On balance, owners rate the Studio Underd0g Full Moon highly for its versatile dial and well-fitting case at the price point.
