AVI-8 Spitfire Type 300 AutomaticvsHamilton Khaki Aviation Converter Auto Chrono

Owners praise the AVI-8 Spitfire Type 300 Automatic for its compelling designs and striking color schemes, with one owner noting the brand consistently prompts purchases. The $450 price point is considered good value, and the watch features a comfortable brown leather strap. However, the included NATO strap feels cheap and is too long for a 7" wrist. One owner reported inaccurate seconds hand movement, and the 15mm thick bronze case is noted as slightly thicker than expected. Overall, owners rate the AVI-8 Spitfire Type 300 Automatic highly for its unique designs and value at the price point, despite some minor strap and case thickness observations.

The Hamilton Khaki Aviation Converter Auto Chrono is widely described as a large 44mm pilot's watch with a functional slide rule bezel. Reviewers note its well-finished steel case, featuring a robust satin-brushed finish with polished accents and chamfers, and a legible blue sunray dial with applied Super-LumiNova markers and old-fashioned hands. It is powered by the H-21-Si automatic chronograph movement, an upgraded ETA-based caliber with a silicon balance spring for anti-magnetic properties, offering a 60-hour power reserve. The watch is rated to 100m water resistance and features a bi-directional slide rule bezel with graduations printed under K1 mineral glass for scratch protection, which is easy to manipulate due to its deeply notched steel design. Some find the slide rule bezel complicated to use without a manual. One owner notes its character does not appeal as much as other slide bezel chronos.
