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.

Monta Atlas

The Monta Atlas is widely praised for its exceptional wearability, with its comfortable 38.5mm case size and buttery bracelet frequently highlighted. Owners and reviewers alike commend its fit and finish, noting a mix of brushed, polished, and blasted surfaces. However, the rehaut on the opaline silver dial is considered nearly illegible for the 24-hour GMT scale, leading some to suggest other dial colors are more practical for GMT functionality. One owner also flagged the crown as less sturdy than anticipated and noted the AR coating attracts fingerprints. Overall, owners and reviewers rate the Monta Atlas highly for its comfortable dimensions and appealing finishing.

From video reviewers

The Monta Opalin Silver's dial is a notable strength, particularly its subtle gradient effect that adds depth to the watch without being too flashy. The watch offers a notable value proposition due to its movement, typically found in more expensive timepieces. The bracelet can be prone to rattle, which might be a trade-off for some buyers.
