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.

Brillier Flieger

Owners widely praise the Brillier Flieger's well-brushed stainless steel case and its 39mm size, though some find the 13mm thickness a bit substantial. Accuracy is consistently reported as exceptional, with readings around +0.4 seconds per day. Opinions are split on the lume, with one owner describing it as "INTENSE" and fully lumed, while another found it weak and short-lasting. The included straps are generally considered undesirable. Overall, owners rate the Brillier Flieger highly for its excellent accuracy and case finishing at the price point.
