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.

Studio Underd0g Mint Choc Chip (Gen3)

Owners and reviewers praise the Studio Underd0g Mint Choc Chip (Gen3) for its unique, visually striking design, featuring an asymmetrical dial, textured two-tone finish, orange chrono hand tips, and chocolate chip hour markers, all housed in a comfortable 38.5mm case with a hand-winding SeaGull ST-1901 movement and a goat-skin strap. Some owners, however, find the watch overpriced for its movement and dial quality, and a few feel it appears toy-like on larger wrists. Overall, owners and reviewers value the Studio Underd0g Mint Choc Chip (Gen3) for its distinctive aesthetic and comfortable wear, despite some reservations about price and perceived scale.
