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.

Yema Diver

One owner reported a water ingress issue on their Yema Diver the first time it got wet in a lake, despite rinsing and inspecting the watch and bezel. Another owner notes this manual wind Yema Diver has a cool patina but is unlikely to be waterproof or gain value. Overall, owners view the Yema Diver as a fun second watch rather than an investment.

From video reviewers

The Swiss Sellita movement is a notable feature. Reviewers did not reach a consensus on any weaknesses.
