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.

Christopher Ward C63 Colchester

The Christopher Ward C63 Colchester is praised for its extremely lightweight, 41mm forged carbon case and dial, weighing only 38 grams, and its COSC-certified Sellita SW200 movement. Some owners report the lume lasts all night, while others note the red seconds hand can be difficult to see in low light. The recessed crown is a point of discussion, with one owner finding it difficult to manipulate due to its thinness and another suggesting it may be gimmicky. The watch is offered at $925. Overall, owners appreciate the unique materials and lightweight design of the Christopher Ward C63 Colchester, though some express concerns about the crown functionality and price point.
