Marathon Steel Navigator SSNAV-D AutovsVenezianico Nereide GMT Grand Tour

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 widely praise the Venezianico Nereide GMT Grand Tour for its beautiful and colorful design, refined muted blue dial, and Italian-made 39mm case with sapphire crystal and AR coating. The bracelet is frequently noted as feeling great on the wrist, and one owner reports excellent accuracy at +-2 seconds per day. Some owners appreciate the dress-casual sport watch feel and the rose gold mirrored bezel portion, while others find the optical glass bezel preferable for reduced glare. However, some find the watch large, and one owner experienced the butterfly clasp opening while swimming. The price is considered steep by some for a Miyota GMT, though others feel it is justified by the improved case finishing and solid feel, especially compared to other movements. The unidirectional 120-click bezel is noted as essentially a diver bezel with a different insert.
