Heuer Autavia Chronograph Ref. 1563

This amazing Heuer Autavia Leonidas, ref. 1563 is in beautiful unpolished original condition and has been recently serviced with all original vintage Heuer parts through my expert watchmaker. It is quite hard to get part for the Heuer Cal. 11/12 nowadays. The more happy I am, that I can present this beautiful piece now in perfect mechanical condition. Befor I’ll get into the details, let’s talk about the legendary movement to understand why this is so special and rare. The first prototypes of the first automatic chronograph were ready to wear in 1968. The movement had a diameter of 31 millimeters and a height of 7.7 millimeters. Its balance wheel oscillated at 19,800 vibrations per hour. From a formal point of view, the movement consisted of two parts: Buren’s Intramatic caliber 1322 in a slightly modified version as the basis and the 8510 chronograph module from Dubois Dépraz. It became official in March 1969: At the same time, the movement, now called Caliber 11 or Chronomatic, was presented in New York and Geneva. The competitor Zenith had not been pre-empted, which a few weeks earlier had also presented an automatic chronograph movement and called it the first (“El Primero”). The construction of the TAG Heuer Monaco caliber 11 required that the crown be positioned at nine o’clock. This technical necessity surprisingly had a psychological effect. At first glance it was so recognizable that the crown had largely lost its function in terms of supplying energy. For left-hand wearers, a crown on the left side of the case is difficult to operate. Soon after the premiere, the caliber 11 was replaced by the caliber 12, which had a frequency increased to 21,600 vibrations as a major innovation. The silver dial is in untouched original condition with all lume present. The provided steel bracelet in not original Heuer, but I left it on the watch as it really fits perfectly.
