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.

Esoteric Watches Bathyal Sol

The Esoteric Watches Bathyal Sol is widely praised for its attractive and unique design, featuring a matte yellow dial with deep sandwich cutouts and old radium lume, complemented by a bezel with deeply grooved, enamel-filled markers. Owners describe it as a dense, hefty, "go anywhere" watch with "insane" lume, noting its homage to the Bulova Snorkel 774. One reviewer flagged potential confusion with the "Eso" vs. "Esoteric" branding and expressed concerns about the long-term durability of the matte black DLC coating. On balance, owners and reviewers rate the Esoteric Watches Bathyal Sol highly for its distinctive dial and robust, go-anywhere build.
