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.

Sugess Heritage S455

Owners appreciate the Sugess Heritage S455's classic, clean dial protected by a sapphire crystal. One owner suggests removing the fake blue jewel on the crown. On balance, owners value the Sugess Heritage S455 for its clean dial design.

From video reviewers

The Sugess Heritage S455 has a smooth and precise bezel action. The watch's value at the price point is a notable strength, with a fully functioning tourbillon typically found in high-end watches. However, the watch has a relatively weak lume brightness.
