What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Glycine Combat Sub

The Glycine Combat Sub is widely praised for its exceptional thinness, with multiple sources highlighting its sub-11mm case height and comfortable wearability, even on smaller wrists. Owners appreciate its unique, non-homage aesthetic, refined finishing, and excellent value for money. Specific positive notes include a buttery smooth bezel action, tasteful indices, crisp font, and a matching date wheel. Accuracy is reported to rival COSC standards by one owner, and durability is noted as exceptional. However, some owners report inconsistent power reserve and sub-par lume that is difficult to read in low light. On balance, owners and community members rate the Glycine Combat Sub highly for its slim profile and unique design at an accessible price point.

From video reviewers

The slim case profile and comfortable wearability are praised. The bezel action received criticism for having slight play and a less-than-satisfying click.

Marathon Steel Navigator SSNAV Auto

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.
