AVI-8 Flyboy Airmaster GMT AutomaticvsBremont S500

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.

Owners widely praise the Bremont S500's excellent Super-LumiNova lume and refined finishing, with many finding its 43mm case comfortable and versatile on the wrist due to short lugs and an offset crown. Reviewers and owners alike note its handsome, rugged design and improved dial legibility for diving. However, some find the 16mm to 16.5mm thickness less practical for daily wear, and one reviewer flags legibility issues with the dark dial and hands. Concerns are raised by one source regarding the three-piece case construction's long-term water resistance for actual diving, while another criticizes the understated bezel markings and the second hand's visibility in low light. The COSC-certified ETA 2836-2 movement provides a 38-hour power reserve. On balance, owners and reviewers rate the Bremont S500 highly for its distinctive design and robust build quality, despite some reservations about its thickness and specific legibility elements.
