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-D Auto

The Marathon Steel Navigator SSNAV-D Auto is praised for its durable construction, featuring a sandblasted steel case with improved lugs, a bi-directional bezel with excellent action, and 100m water resistance. Owners appreciate the constant visibility provided by self-illuminating tritium gas tubes and the precision of its ETA F06.412 quartz movement, which offers accuracy to about 10 seconds per year. The watch includes a GMT bezel for dual timekeeping and a synthetic sapphire crystal. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Auto highly for its robust tool-watch design and reliable tritium illumination.

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.
