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

Owners widely praise the Glycine Combat Sub for its exceptional thinness, with many noting its 10.4mm to 10.8mm profile for a diver, perfect proportions, and solid build quality that offers significant value, especially at discounted prices. Its unique aesthetic is appreciated for avoiding homage looks, and the lug design contributes to a smaller perceived wear size despite its 42mm case. Some owners report an inconsistent power reserve and sub-par lume that can be difficult to read at night, while one owner noted a slightly off-color lume pip on the chapter ring. Overall, owners rate the Glycine Combat Sub highly for its refined feel, slim profile, and value proposition.
