Marathon Steel Navigator SSNAV-D AutovsTornek-Rayville TR-660 Acrylic Non-date

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.

The Tornek-Rayville TR-660 Acrylic Non-date is a 40mm bead-blasted stainless steel watch with a utilitarian matte black dial and a moisture detector, measuring 14.7mm thick and 48.5mm lug-to-lug, featuring a subtly domed, AR-coated crystal. One owner notes a preference for a different watch's bezel-locking mechanism but appreciates the TR-660's 20mm lug size. Another owner reports damage to the case and bezel, though it includes unused and worn straps. On balance, owners find the Tornek-Rayville TR-660 Acrylic Non-date to have a timeless design that remains appealing.
