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.

Zelos Spearfish GMT

The Zelos Spearfish GMT is widely praised for its exceptional value, with reviewers highlighting its superb finishing, flawless machining, and a tool-less micro-adjustment clasp that exceeds its price point. It features a La Joux-Perret G100 movement with a 68-hour power reserve, achieving an average accuracy of +2.6 seconds per day, or a Miyota 9075 movement offering flier-style GMT functionality. The 40mm case and bidirectional 48-click ceramic bezel are well-executed, though one reviewer noted a minor compromise in the end link fit. Overall, owners and reviewers rate the Zelos Spearfish GMT highly for its impressive finishing and value proposition.
