Glycine Airman GMTvsMarathon Steel Navigator SSNAV 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 Auto is praised for its high-accuracy quartz movement, with owners noting its comfort and reliable performance. Reviewers highlight its functional tool-watch appeal, featuring a sandblasted steel case, tritium tubes for constant low-light visibility, and 100-meter water resistance. One owner finds the 41mm case runs a bit small. The Marathon Steel Navigator SSNAV Auto utilizes an ETA F06.412 quartz movement with a claimed accuracy of +/- 10 seconds per year and includes a GMT bidirectional bezel. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV Auto highly for its comfortable wear and dependable, high-accuracy quartz movement.
