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 GMT

Owners widely praise the Glycine Airman GMT for its value and classic design, with specific appreciation for its 39mm sizing, 200m water resistance, and beefy signed crowns. Reviewers highlight its faithful re-issue nature, retaining vintage features like the plexiglass crystal and locking friction bezel with a thumbscrew crown, while some owners note its subtle blue degrade dial and red-tipped GMT hand. Accuracy from its Sellita-based automatic movement is described as acceptable, though some owners find the dual 12-hour and 24-hour scales confusing and the slim GMT hand difficult to read. On balance, enthusiasts and reviewers rate the Glycine Airman GMT highly for its vintage charm and robust build at its price point.

Marathon GSAR (Government Search & Rescue) Diver's Automatic

The Marathon GSAR (Government Search & Rescue) Diver's Automatic is widely praised for its legibility, comfort, and exceptional tritium illumination, with reviewers highlighting its utilitarian, military-equipment feel and a 41mm case size considered ideal. Owners appreciate its grippy bezel and the 300 meters of water resistance provided by the screw-down crown, deeming it a solid value for a Swiss-made tool watch. Some owners report quality control issues, with one user needing to warranty two watches, and another notes the GSAR wears taller than other models, leading to occasional bumping. The reliable ETA 2824-A2 movement is a consistent feature. Overall, owners and reviewers rate the Marathon GSAR (Government Search & Rescue) Diver's Automatic highly for its bright tritium lume and robust, no-nonsense tool watch design.
