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.

Horage Decaflux

The Horage Decaflux is praised for its innovative in-house K3 movement, featuring a silicon escapement and a 96-hour power reserve, along with chronometer certification and a slim 9.98mm profile. Reviewers note its tinted sapphire crystal, lightning bolt seconds hand, and bracelet with an integrated vibe and thin clasp. The watch is priced at CHF 2,750, with preorder pricing at CHF 2,500, representing a strong value for an in-house Swiss movement. Some reviewers find the lightning bolt seconds hand slightly too wide and note a direct design homage to the Rolex Milgauss. On balance, reviewers rate the Horage Decaflux highly for its technical innovation and value proposition at its price point.
