What people say

Owners + reviewers, side by side

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

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.

Boldr Odyssey Bronze

The Boldr Odyssey Bronze is widely praised for its robust, ship-like aesthetic and substantial feel, with its meteorite dial and OEM Horween strap highlighted as unique features. Owners feel the style, fit, finish, and specifications compensate for criticisms regarding the movements used at its price point. On balance, owners rate the Boldr Odyssey Bronze highly for its distinctive aesthetic and quality finishing.

From video reviewers

The 500m water resistance and Lumicast lume are standout features. The 45mm+ case size is a drawback for some wrists.
