More about Hanhart: 

Founded in Diessenhofen, Switzerland in 1882 by Johan A. Hanhart, primarily as a retail operation before relocating to Germany in 1902.  There, in Germany, Hanhart experimented with the manufacture of different models before launching its first stop watches in 1924.

In 1938, Hanhart developed its first monopusher chronograph, the caliber 40, called the “Primus.” During the war, production of watches was limited, and then, from 1945 through 1948, production halted completely.

In 2008, the company relocated back to Switzerland with a new office located steps away from its original Diessenhofen location.

The case back is signed with the three stars of Cétéhor (Centre Technique de l'Industrie Horlogère) along with the heraldic emblem of Besançon.
