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 PRC 100 Solar

Owners and reviewers highlight the Tissot PRC 100 Solar's value and modern, urban aesthetic, with its slim 9.2mm case and good finishing for the price. The solar movement is a key feature, offering a 14-month power reserve and rapid charging capabilities. Some owners find the dial colors a bit uninspired, and the date window placement is disliked, while the second hand's ticking is noted as a drawback compared to automatic movements. The watch's 39mm case is considered versatile, though some prefer a smaller 35-37mm size. Overall, owners and reviewers consider the Tissot PRC 100 Solar a versatile daily wear, particularly for its solar technology and Swiss-made appeal at its price point.
