Hamilton Khaki Aviation compatibility

Wear a smartwatch with your Hamilton Khaki Aviation

In short 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.

  • Where can I buy Smartlet for the Hamilton Khaki Aviation?
    Smartlet is available at smartlet.io in Classic, Shadow, and Titanium. All finishes are compatible with Khaki Aviation references at 20mm and 22mm.
  • Beschädigt oder verändert Smartlet meine mechanische Uhr?
    Nein. Smartlet ersetzt Ihr Standard-Uhrenarmband mit dem vorhandenen Federstift-System. Es werden keine dauerhaften Änderungen am Uhrengehäuse, den Hörnchen oder dem Zifferblatt vorgenommen. Der Vorgang ist vollständig reversibel und dauert nur Sekunden. Ihre mechanische Uhr bleibt unbeeinträchtigt und kann jederzeit unabhängig getragen werden, indem Sie einfach das Originalarmband wieder anbringen. Smartlet ist nach Uhrmacher-Toleranzen konstruiert und wird mit der gleichen Sorgfalt getestet, die auch in die Uhren fließt, mit denen es kombiniert wird.
