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 (General Purpose Quartz) Field Watch

Owners widely praise the Marathon GPQ (General Purpose Quartz) Field Watch for its rugged quartz movement, accuracy, and tritium lume. Reviewers and owners alike highlight its solid build, legibility, and comfortable, lightweight wear, making it particularly well-suited for smaller wrists. Some owners, however, consider the price point of $350-420 to be somewhat high. On balance, the consensus is that owners rate the Marathon GPQ (General Purpose Quartz) Field Watch highly for its dependable quartz accuracy and excellent tritium lume.

Longines CONQUEST

Owners and reviewers widely praise the Longines CONQUEST for its high-quality finishing, versatile design, and exceptional value, with many highlighting its comfortable wearability and solid build. Accuracy figures are generally positive, with one owner reporting +1/+2 seconds per day. However, several owners note that the bracelet lacks micro-adjustment, which can affect fit, and some find the lume to be weak or inconsistently applied across variants. One owner also mentioned the crown rubbing against the wrist. On balance, owners and reviewers rate the Longines CONQUEST highly for its blend of elegant design and robust build at an accessible price point.

From video reviewers

The perfectly balanced case size is a key strength of the Longines Conquest. A notable weakness is the somewhat lacking lume brightness. Reviewers disagree on the ideal case size, with one preferring 38mm and the other 39mm.
