Hamilton Khaki Field Expedition AutovsMarathon GSAR (Government Search & Rescue) Diver's Automatic

The Hamilton Khaki Field Expedition Auto is widely praised for its value, robust build, and versatility as a "Go Anywhere, Do Anything" timepiece. Owners and reviewers highlight the H-10 movement's 80-hour power reserve and accurate timekeeping, with figures ranging from +4 seconds per day to within COSC parameters. Its legibility is a consistent strength, featuring clear Arabic numerals and Super-LumiNova, and wearability is noted as excellent, especially in the 37mm size. The brushed steel case and compass bezel contribute to its tool-like appeal. However, some owners report water ingress issues due to the non-screw-down crown, and the practical utility of the compass bezel is questioned by reviewers, though it adds to the watch's aesthetic. Some find the OEM leather straps uncomfortable. Overall, owners and reviewers rate the Hamilton Khaki Field Expedition Auto highly for its superb value and robust, versatile design.

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.
