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 excellent value, thin case height (ranging from 10.4mm to 10.8mm), and comfortable wearability due to downward-curving lugs, with owners noting its quality and finishing punch well above its price point. Reviewers and owners consistently highlight its smooth bezel action, crisp font, and a unique aesthetic that avoids being a direct homage. However, criticisms include sub-par lume that is difficult to read in low light and an inconsistent power reserve, with some owners suggesting it may require servicing. Opinions are split on the 42mm size, with some finding it perfect and others preferring a smaller variant. On balance, owners and reviewers rate the Glycine Combat Sub highly for its exceptional thinness and quality finishing at its price point.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
