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 Bradner GMT

The Spinnaker Bradner GMT is praised for its awesome lume and comfortable wearability, with one owner noting the rubber strap is very comfortable and the beads of rice bracelet fits well on smaller wrists. Some find its 15mm thickness and bold colorway may not appeal to everyone, and one owner views it as more of a casual GMT with tool-watch styling than a diver. Overall, owners rate the Spinnaker Bradner GMT highly for its value and comfortable wearability.
