Marathon Steel Navigator SSNAV-D AutovsKUOE ROYAL SMITH 90-010

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 praise the KUOE ROYAL SMITH's elegant 37mm size, symmetrical bicompax layout, and crisp chronograph pushers with a swift reset. The salmon dial is described as copper-toned with highly polished, legible Breguet numerals. Some owners find the 13mm thickness and 43mm lug-to-lug wearable, while others note the 14.3mm thickness detracts from wearability. The TMI NE86A movement has a claimed 45-hour power reserve and accuracy ranging from +25/-15 seconds per day. On balance, owners and reviewers appreciate the KUOE ROYAL SMITH for its retro charm and enjoyable chronograph operation, despite some reservations about its thickness.
