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 HYDROCONQUEST

Owners widely praise the Longines HydroConquest's dial and finishing, with one owner finding it superior to a Rolex Submariner. The movement is noted as well-regulated, losing about 2 seconds per day. The watch is considered a versatile everyday or business-casual option, offering good value. However, owners criticize the bracelet for lacking tool-less micro-adjustment and describe winding the crown as a nuisance. Some in the line report tiny GMT markers that are difficult to read and the absence of a quick date adjust feature. Overall, owners rate the Longines HydroConquest highly for its finishing and value.
