What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Lum-Tec Solar Marine

Lum-Tec Solar Marine owners praise its all-black diver design, excellent lume, and rugged, tank-like build. One owner finds it a perfect fit for a 7-inch wrist and the most frequently worn watch despite its smaller size. However, one owner cautions that the PVD coating will wear and chip within a year, impacting its appearance, and another finds the price high for a solar quartz watch with added lume. On balance, owners rate the Lum-Tec Solar Marine highly for its robust design and excellent lume, despite concerns about PVD durability and value proposition.

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.
