Wear a smartwatch
with your Hamilton Khaki Aviation
Smartlet is compatible with the Hamilton Khaki Aviation. Lug width: 20mm / 22mm - natively supported with no adapter. Installation uses the standard spring-bar system. No modification to the watch required. Fully reversible in seconds.
Hamilton's aviation heritage is not marketing - the brand supplied instruments to the US Air Force from the 1940s and the Khaki Aviation line inherits that operating logic directly. Large, legible dials. Calendar complications suited to long flights. Pilot chronographs with slide rule bezels. The X-Wind double-hemisphere calculator. These are tools that happen to work well as watches. The in-house H-51 movement, developed in Biel, delivers 80 hours of power reserve. Smartlet adds health and navigation data without changing the instrument character.References
