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 Eagle 2

Owners widely praise the Zelos Eagle 2's unique meteorite dial and titanium case, with one owner describing it as a "work of art" featuring a fully lumed dial and a scratch-resistant 1,200 Vickers hardness-coated case. The LaJoux Perret G100Soigne movement provides a 68-hour power reserve. Some owners, however, find the dial layout "ugly" and the font thick, while others note minor QC issues like misaligned markers. On balance, owners rate the Zelos Eagle 2 highly for its distinctive meteorite dial and titanium construction at its price point.

From video reviewers

The watch's compact size is a notable strength, with a 39mm diameter case and 11mm thickness making it suitable for a pilot's watch. A potential weakness is the lug-to-lug fit, which may be too large for smaller wrists. Reviewers disagree on the bezel, with one reviewer highlighting the Cerakote finish as a standout feature, while another mentions the watch's bezel in passing without comment.
