Vintage Heuer Autavia Auto Chronograph Men Watch

Heuer Autavia contains the Cal 12 automatic winding chronometer chronograph. The movement was developed first as the Cal 11 by an association of Buren-Hamilton, Breitling, Dubois-Depraz, and Heuer-Leonidas in 1969. The movement was offered in watches by each of the manufacturers. It was used in the now popular Heuer Autavia, Carrera, Monaco. In 1972, the movement was upraded to the Cal 12 at 21,600 bph to achieve true chronometer standards. The winding/setting stem is on the left rather than right. This was done intentionally to make the watches stand out from other chronographs of the time. Turning the bezel activates a small internal gear that rotates the outer dial ring for time and speed calculations. The chronograph functions as a 24 hr timer with two sub-dials. This watch is in great condition with Heuer signed stainless steel bracelet. All functions working correctly as you can see in this video.
