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.

Phoibos Narwhal

Owners widely praise the Phoibos Narwhal's 38mm size and slim 11.5mm height for a 200m diver, noting it wears well on smaller wrists and its case shape resembles an integrated bracelet. The aventurine and Howlite dials are described as captivating, and some appreciate the contrast finishing and retro looks. However, some owners criticize misaligned markers and a tilted date window, with one owner finding the hands thick and popsicle-style. The value proposition is debated, with some finding it a good buy at $390 but others considering $480-$490 too much due to a slabby design and difficult-to-size bracelet. On balance, owners find the Phoibos Narwhal appealing for its design and wearability, though quality control and pricing are points of contention for some.

From video reviewers

The unique stone dial is a significant strength. The bracelet's refinement is a weakness. Reviewers disagree on the dial's appeal, with one highlighting its sunburst effect and applied indices, while another focuses on the natural stone variation.
