What people say

Owners + reviewers, side by side

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

Boldr Expedition Enigmath

The watch's slide rule function is a convenient feature, allowing for calculations on the go. One potential drawback is the use of the Japanese Miyota 9039 movement, which may be a trade-off for some buyers. Reviewers disagree on whether the quick 'on the fly' adjust bracelet is a more significant advantage than the watch's sapphire crystal for durability and scratch resistance.

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.
