The Hamilton Khaki Aviation Takeoff Auto Chrono (ref. h76786733) is an automatic pilot watch, with a 46mm stainless steel case, 16.2mm thick, powered by the H-31 movement and a 60-hour power reserve. Water resistance is rated to 50m, under a sapphire crystal. Manufacturer MSRP is $3,575.
The Hamilton Khaki Aviation Takeoff Auto Chrono is noted for its unique bullhead chronograph design and detachable functionality for desktop display, with a PVD case and yellow accents. Owners praise its solid construction, precise indices, and smooth bezel action, alongside a detailed champagne dial, crisp printing, and retro hands with good lume. However, its extreme thickness and 46.3mm width are flagged as compromising daily wearability, and some find the sizable crown guards hinder usability, while a rattling bracelet with a difficult-to-remove design is also mentioned. The watch uses the Hamilton H-31 automatic chronograph movement with a 60-hour power reserve and is a limited edition of 1999 units. On balance, owners and reviewers appreciate the Hamilton Khaki Aviation Takeoff Auto Chrono for its distinctive design and pilot-inspired legibility, despite practical concerns regarding its size and wearability.
