Hamilton Khaki Aviation Converter Auto ChronovsDOXA SUB 200 C-GRAPH II

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 DOXA SUB 200 C-Graph II is widely praised for its improved wearability with a 42mm case size and flatter lugs, a significant downsizing from its predecessor. Reviewers and owners highlight its fantastic finishing, sharp contrasts, and smooth crown action, with one owner noting exceptional accuracy of +1 second per day even after drops. The watch retains 200m water resistance and features updated sun-brushed dials, a ceramic bezel option, and Super-LumiNova accents. It is powered by the Sellita SW510 movement, offering a 56-hour power reserve. Prices range from $2,850 to $2,990 USD. On balance, owners and reviewers rate the DOXA SUB 200 C-Graph II highly for its refined finishing and more wearable dimensions at its price point.
