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.

LONGINES SPIRIT FLYBACK

Owners widely praise the Longines Spirit Flyback for its attractive design, well-finished titanium case, and value as a chronometer-certified flyback chronograph. Specific positive notes include its fun and useful flyback function for cooking, and the perceived adventure-ready, indestructible feel of the titanium model. However, reviewers and owners consistently flag its 17mm thickness as a significant detractor from wearability, with some finding it too chunky for daily wear. There is also a split opinion on the dial design, with some preferring the older five-star motif and gold hands/markers, while others appreciate the cleaner, simplified dial and cutoff numerals. The Longines Spirit Flyback is priced around $5,350-$6,500 USD. Overall, owners and reviewers rate the Longines Spirit Flyback highly for its flyback chronograph complication and attractive design, despite widespread concerns about its thickness.

From video reviewers

The Spirit Flyback's heritage-inspired design is a notable strength, with a distinctive look reminiscent of the original Flyback Chronograph. The watch's price point is somewhat high compared to its competitors, which might be a drawback for some buyers. Reviewers disagree on the watch's design, with one reviewer feeling it needed more of an edge to stand out in the Spirit collection, while another praises its heritage-inspired style.
