Wear a smartwatch
with your Hamilton Khaki Field
The Khaki Field descends from watches Hamilton supplied to the US military in the 1940s. Clean legibility, robust construction, and a design that has changed very little since. Smartlet One replaces your Khaki Field strap and clips your Apple Watch or Garmin Venu onto the same wrist. Field-tested mechanical precision alongside digital health tracking.
