What people say

Owners + reviewers, side by side

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

Marathon Steel Navigator SSNAV Auto

The Marathon Steel Navigator SSNAV Auto is praised for its high-accuracy quartz movement, with owners noting its comfort and reliable performance. Reviewers highlight its functional tool-watch appeal, featuring a sandblasted steel case, tritium tubes for constant low-light visibility, and 100-meter water resistance. One owner finds the 41mm case runs a bit small. The Marathon Steel Navigator SSNAV Auto utilizes an ETA F06.412 quartz movement with a claimed accuracy of +/- 10 seconds per year and includes a GMT bidirectional bezel. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV Auto highly for its comfortable wear and dependable, high-accuracy quartz movement.

Sternglas Naos Solar

Owners widely praise the Sternglas Naos Solar for its elegant Bauhaus-inspired minimalist dial, slim profile, and value for money. The scratch-resistant curved sapphire crystal and functional date mechanism are noted as durable features, with one owner reporting good wear over a year. The solar power and accuracy are highlighted as practical advantages over automatic movements, which some find loud. However, opinions are split, with some owners finding the watch underwhelming and cheap-looking, like a toy, while others love its appearance in person and its clean, appealing design as a smartwatch alternative. The stock leather strap is described as decent but basic and potentially short for larger wrists, with one owner advising a third-party replacement for durability. One owner of a different variant noted the date font is too small to be useful.
