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

The Marathon GSAR (Government Search & Rescue) Diver's Automatic is widely praised as a versatile and well-made tool watch, with reviewers highlighting its legibility, utilitarian build, and comfort. Owners appreciate the tritium gas tubes for exceptional illumination in darkness, a feature noted as superior to some alternatives. The 41mm case size is considered ideal by some, though one owner found it wore tall and bumped on objects. While the watch is generally seen as a solid value for a Swiss-made tool watch, some owners have reported quality control issues requiring warranty service. Overall, owners and reviewers rate the Marathon GSAR (Government Search & Rescue) Diver's Automatic highly for its robust build and constant legibility from tritium.

One owner notes the bezel markings do not align perfectly, and another reports the lume is comparable to a cheap Casio.
