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.

Citizen Tsuyosa

The Citizen Tsuyosa is praised for its gorgeous dial and nice finishing, with owners finding its white dial versatile and its wrist presence excellent. It is considered a fun, people-pleasing watch, especially for summer, and offers excellent value. However, the 40-hour power reserve requires resetting after weekends, and the integrated bracelet rattles. One owner notes the Miyota 8210 movement is noisy and considered boring for enthusiasts, with initial accuracy issues that resolved themselves. The US price of $450 is seen as too high, with better value around $300 in the EU. On balance, owners rate the Citizen Tsuyosa highly for its dial and finishing at the price, despite caveats regarding the bracelet and movement.

From video reviewers

The Citizen Tsuyosa's compact size and versatility are notable strengths, with the 37mm case being a welcome addition to the series. The watch's price point under SGD 600 is also a positive aspect. A weakness is the integrated bracelet's potential for rattle.
