What people say

Owners + reviewers, side by side

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

Glycine Airman Worldtimer GMT Dual Time

Owners widely praise the Glycine Airman Worldtimer GMT Dual Time for its comfortable 40mm size, attractive aesthetics, blue GMT hand, sapphire crystal with blue AR coating, and locking bezel. Some owners find it a significant improvement over previous Airman models, with one reporting good timekeeping. However, the dual 24-hour and GMT hands are noted by some as making local time setting less intuitive than a purist 24-hour dial. On balance, owners and reviewers appreciate the Glycine Airman Worldtimer GMT Dual Time for its comfortable wearability and classic design elements.

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.
