Hamilton Khaki Aviation Converter Auto ChronovsFurlan Marri Flyback

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.

The Furlan Marri Flyback is widely praised for its vintage-inspired design, 38mm case size, and elegant sector dials, with several sources highlighting its exceptional value proposition. Owners and reviewers consistently commend the watch's classical dimensions and thinness, particularly the 10.9mm thickness mentioned by one source. The Sellita AMT5100 movement, featuring a flyback function and column-wheel, is noted for its decoration and reliability, offering a power reserve around 58-63 hours. Readability is also a strong point, with one reference specifically mentioning the taupe dial's excellent contrast. However, one reviewer flags the pushers as appearing small, and another criticizes the case thickness exceeding 13mm, describing it as a "hamburger-on-wrist" despite efforts to mitigate the bulk with a short lug-to-lug and domed crystal. Overall, owners and reviewers rate the Furlan Marri Flyback highly for its sophisticated vintage aesthetics and strong value at its price point.
