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 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.
