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.

Zelos Nova 37

Owners widely praise the Zelos Nova 37's spectacular 37mm dimensions and extremely light, thin wearability. The meteorite dial is frequently highlighted as a captivating feature, though some reviewers suggest simpler indices would improve legibility over the Arabic numerals. The watch is considered a considerable value at $1,999. On balance, owners and reviewers rate the Zelos Nova 37 highly for its excellent dimensions and dial execution at the price.
