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.

Zelos Vitesse

Owners widely praise the Zelos Vitesse for its vintage motorsport design and striking dial options, with particular appreciation for the salmon and panda configurations and their finishing. The bracelet, clasp, and overall value at $1200 are frequently highlighted as strong points. Some owners note the watch sits high on the wrist, and a few have observed minor cosmetic imperfections on subdials. The La Joux Perret L100 movement's accuracy varies, with one report of +5 seconds per day, and several owners find the winding action stiff and noisy, the pushers sticky, and the screw-down crown's feel underwhelming. On balance, owners rate the Zelos Vitesse highly for its captivating dial and strong value proposition, despite some reservations about the chronograph's operational feel and case height.
