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.

Tissot PR 100

Owners widely praise the Tissot PR 100 for its exceptional value, with many noting its sapphire crystal, robust build, and attractive design. The Powermatic 80 variants are particularly lauded for their 80-hour power reserve and accuracy, with some reporting deviations as low as +/- 1-2 seconds per day. Owners appreciate the clean dials and practical clasps, finding the 39mm and 40mm sizes versatile. However, some owners report the crystal easily picks up fingerprints, and the stainless steel case and bracelet can show scratches or wear over time, with one instance of a bracelet falling apart after five years. Some also note that only the hands have lume, and the seconds hand may not perfectly align with markers on certain quartz models. Overall, owners rate the Tissot PR 100 highly for its impressive value and solid construction, making it a well-regarded entry-level Swiss timepiece.
