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 Leviathan

Owners widely report the Phoibos Leviathan offers a vintage experience at an affordable price due to its proportions and conservative design. However, the watch is considered well-made and sturdy but quite heavy, with a 45mm x 54mm lug-to-lug case and a 15.5mm thickness, leading some owners to replace the stock band. On balance, owners rate the Phoibos Leviathan highly for its vintage feel and sturdy build at its price point.

From video reviewers

The watch features 500m water resistance and a Seiko NH35 automatic movement. The case size is a point of contention, with reviewers noting it is substantial and may overwhelm smaller wrists, while others highlight a 40mm case size as an improvement.
