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 Project Passion Crew

The Studio Underd0g Project Passion Crew is noted for its unique "coarse dégradé amber and royal purple" multi-layer dial and manual-wind Sellita SW510 M chronograph movement with a 63-hour power reserve. However, its accessibility is severely limited as it is only sold as a $64,900 set with another watch. Overall, reviewers highlight the distinctive dial and chronograph movement as key features, though the high price and bundled sale significantly restrict its availability.
