Glycine Airman GMTvsMarathon Steel Navigator SSNAV-D Auto

Owners widely praise the Glycine Airman GMT for its value and classic design, with specific appreciation for its 39mm sizing, 200m water resistance, and beefy signed crowns. Reviewers highlight its faithful re-issue nature, retaining vintage features like the plexiglass crystal and locking friction bezel with a thumbscrew crown, while some owners note its subtle blue degrade dial and red-tipped GMT hand. Accuracy from its Sellita-based automatic movement is described as acceptable, though some owners find the dual 12-hour and 24-hour scales confusing and the slim GMT hand difficult to read. On balance, enthusiasts and reviewers rate the Glycine Airman GMT highly for its vintage charm and robust build at its price point.

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.
