Glycine Airman GMTvsMarathon Steel Navigator SSNAV Auto

Owners widely appreciate the Glycine Airman GMT's classic pilot design and consider it a well-built watch, with some noting the 39mm models offer perfect sizing and 200m water resistance. Reviewers praise the plexiglass crystal and matte dial, while some owners find the GMT hand visually similar to the minute hand, making it difficult to read. Accuracy from the Sellita-based movement is described as acceptable, though dial lume pips are noted as weaker than the hands. On balance, owners and reviewers value the Glycine Airman GMT for its faithful reproduction of a classic pilot watch design, despite some legibility concerns with the GMT hand.

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.
