What people say

Owners + reviewers, side by side

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

AVI-8 Flyboy Airmaster GMT Automatic

Owners widely praise the AVI-8 Flyboy Airmaster GMT Automatic for its robust build quality, intricate three-timezone function, and crisp dial texture. The watch is noted for its wearable 41mm case size and 48.5mm lug-to-lug, with an internally positioned GMT complication that maintains a clean dial appearance. Some owners report the stock leather strap feels cheap and limits strap changing options. On balance, owners rate the AVI-8 Flyboy Airmaster GMT Automatic highly for its solid finishing and value, particularly highlighting the dial's depth and texture.

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.
