Marathon Steel Navigator SSNAV AutovsSeiko Presage Classic Series “Craftsmanship” Enamel Dial

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.

Owners and reviewers widely praise the Seiko Presage Classic Series “Craftsmanship” Enamel Dial for its high-quality, handcrafted enamel dials, with specific commendations for the depth and subtle gloss of urushi lacquer and the excellent legibility of minimalistic markers and contrasting hands. The watches are frequently cited as offering significant value, with one reviewer noting the SPB163 as a great value at €1,300, and another highlighting the series' impressive 100M water resistance and Japanese design inspiration at $1,300 USD. However, the 12.4mm to 12.8mm thickness is noted by multiple sources as a potential area for improvement, with a preference for under 12mm, and one owner dislikes the date window. Accuracy figures for the 6R27 movement range from -15 to +25 seconds per day, and its power reserve is closer to 35-40 hours than the advertised 45 hours.
