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.

Sternglas Naos XL

Owners widely praise the Sternglas Naos XL for its versatile Bauhaus design, domed sapphire crystal, and value, with some finding its larger size comfortable and refined for its price. However, opinions are split on its aesthetic appeal, with one owner finding the hands and face underwhelming, while others appreciate the minimalistic dial. The date font is noted as too small to be useful by one owner, and the stock strap is generally considered basic or prone to wear. Accuracy figures vary, with one owner reporting a Miyota movement running fast and another noting +13 seconds per day. Overall, owners rate the Sternglas Naos XL highly for its Bauhaus aesthetics and affordability, despite some reservations about the movement and strap.
