Marathon Steel Navigator SSNAV-D AutovsGrand Seiko SBGD202

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 Grand Seiko SBGD202 is widely lauded for its mesmerizing "Starlight" or "stardust" dial, achieved through a new plating and painting technique, and its exceptional craftsmanship, which reviewers compare favorably to high-end Swiss and German brands. The manual-wind Caliber 9R01 Spring Drive movement offers an 8-day power reserve and impressive accuracy up to 0.5 seconds per day, with an independent hour hand setting. However, some owners find the movement finishing on the display back to be plain. The SBGD202 is priced at 52,800 Euros. On balance, the consensus is that the Grand Seiko SBGD202 is a highly beautiful three-hand watch, with its dial and movement accuracy being the primary reasons for its acclaim.
