Marathon Steel Navigator SSNAV-D AutovsOrient Multi-Year Calendar

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.

Owners report the Orient Multi-Year Calendar features a complex analog display for tracking days and dates across multiple years, housed in a 45mm stainless steel case with 100m water resistance. Some owners view the watch as a visually appealing novelty, noting that manual adjustment is required for months and that the older 20-year calendar version is difficult to find. One owner observed only light signs of wear on their watch, with minor desk rash on the buckle visible only under magnification. On balance, owners appreciate the unique calendar complication as a visually appealing novelty.
