Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
The Squale 2001 is praised for its faithful vintage reproduction, featuring a funky design, vivid colors, and impressive 600m water resistance. Owners note the 40mm case fits well on a 6.5-inch wrist, and the ladder bracelet adds a special touch to its unique look. The watch allows for custom orders, with potential requests for unique dials, caseback engravings, bezels, or straps. Drawbacks noted include the bidirectional bezel's tendency to collect fingerprints and a dated 38-hour power reserve. One owner reported minor scratches on the back of the lugs after two wears. Overall, owners and reviewers rate the Squale 2001 highly for its authentic vintage design and customization options.
