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.

Maen Manhattan Ultra Thin

The Maen Manhattan Ultra Thin is widely praised for its slim case, with reviewers noting a 6.9mm or 7.1mm thickness, and its elegant, vintage-inspired styling. Specific design elements highlighted include a Côtes de Genève or hammered "Tuscan" dial finish and an integrated bracelet. The hand-wound ETA Pesaux 7001 movement is noted for its role in achieving the thin profile, offering a 42-hour power reserve. However, the black text on the vertically striped dial can be difficult to read, and the integrated bracelet lacks a quick-release system. Some reviewers expressed a desire for a 38mm case size option. Overall, reviewers rate the Maen Manhattan Ultra Thin highly for its slim, elegant design and vintage aesthetic at its price point.

From video reviewers

The ultra-thin profile is a standout feature. The value proposition is a point of discussion.
