Autavia History
The Autavia (the name being mix of AUTomobile and AVIAtion) was first introduced by Heuer in 1962. Early models used manual-wind Valjoux movements, such as the Valjoux 72.
Introduction of the Caliber 12
By the late 1960s, the race was on to develop the first automatic chronograph was in full swing. Heuer, in collaboration with Breitling, Hamilton-Buren, and Dubois Dépraz, helped develop the Chronomatic project. This led to the launch of the Caliber 11 in 1969, one of the world’s first automatic chronograph movements. (See How Heuer, Breitling, And Hamilton Brought The Automatic Chronograph To The World for more information)
The Caliber 12, released shortly after, was an improved version of the Caliber 11 with a higher beat rate (21,600 vph vs. 19,800) and other refinements for better reliability and accuracy. Heuer began fitting the Autavia with the Caliber 12 in the early 1970s.
