Wear a smartwatch with your Hanhart

Johann A. Hanhart opened a watch shop in Diessenhofen, Switzerland, on 1 July 1882, and moved the business to Schwenningen in southern Germany in 1902. In 1938 the brand put its first single-button chronograph, the Calibre 40, into series production, with pilot's chronographs following in 1939. In the 1950s the 417 became the first pilot's chronograph of the newly founded German armed forces, which Hanhart supplied for almost ten years. Today its instrument watches are made in Gütenbach, in the Black Forest. Most Hanhart references hold their strap on standard spring bars, which is all Smartlet One needs: the original strap comes off, the Smartlet strap goes on, and the watch itself is not modified.
