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 No. 1 GMT

Owners widely praise the Glycine Airman No. 1 GMT for its historical significance and attractive dial. However, some find the 36mm case size to be a bit small, and the GMT hand can be difficult to distinguish from the minute hand. The watch has a very limited 3ATM water resistance. Later versions feature sapphire crystals, differing from earlier plexi models. Overall, owners value the Glycine Airman No. 1 GMT for its historical appeal and dial design, despite minor legibility and sizing concerns.

From video reviewers

The case finishing and dial colors are praised. The value proposition is tied to a sale price, with questions about long-term competitiveness.

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.
