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-D Quartz

The Marathon Steel Navigator SSNAV-D Quartz is widely praised for its high-accuracy Swiss Made ETA F06.412 HeavyDrive-PreciDrive quartz movement, rated at +/- 10 seconds per year, and its tritium lume. Reviewers and owners highlight its functional tool-watch appeal, noting the sandblasted steel case with an asymmetric design, excellent bi-directional bezel action, and drilled lug holes. Some owners find it perfectly suited for sport/rugged use, though not necessarily as an everyday watch. One owner points out that the case's distinctive asymmetry deviates from current aesthetic trends. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Quartz highly for its robust build and exceptional timekeeping accuracy at its price point.
