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.

Grand Seiko SBGH368

The Grand Seiko SBGH368 is praised for its aggressive styling and textured copper-pink dial, inspired by cherry blossoms. Reviewers highlight its 38mm 18k rose gold 62GS case, featuring Zaratsu polishing, as a standout element. The watch is powered by the Hi-Beat Caliber 9S85 movement, which is regulated to -3/+5 seconds per day and offers a 55-hour power reserve. It also features 100m water resistance. One reviewer notes that the brown crocodile strap, while handsome, would ideally be replaced with a water-resistant option given the watch's 100m water resistance. There is also a question raised about whether a movement with a longer power reserve could have been utilized. The Grand Seiko SBGH368 retails for $31,200. Overall, reviewers consider the Grand Seiko SBGH368 a favorite gold-cased Grand Seiko, with its rose gold case and cherry blossom dial described as an exceptional combination.
