Quartz CrisisДЄs a major customer of ValjouxвЂ™s manual wind movements during the 1960s, it was no surprise that Heuer would offer watches with the 7750 movement, despite having its own Calibre 11 engine. The first versions of the Valjoux 7750 came in two frequencies- 21,600 bph and 28,800 bph, each with 17 jewels. Because it free-spins in one direction, you can sometimes feel the movement вЂњwobblingвЂќ on yourВ wrist. The 7750 is mono-directional (only winds in one direction), and so has a relatively large and heavy oscillating weight that can reach high speeds when rotating in its non-winding direction. There is also a sonic signature: the sound of the rotor. Based on the manual-wind Valjoux 7733 (itself a descendent of the Venus 188), the 7750 was first available in watches in 1973/4, having been one of the first movements to be designed with the aid of a computer.ДЄ reliable, cost-effective calibre, the 7750 is relatively thick and large compared to its contemporary competitors. Between 1969-1974, there was a golden age of innovation, with the Heuer- Breitling- Hamilton Chronomatic (1969), Seiko 6139 (1969), Zenith El Primero (1969) and Lemania 5100 (1973) all being launched.ДЄlthough Valjoux was the leader in manual-wind chronographs, it was slow to the self-winding party, appointing Edmond Capt to lead the development of a new movement in the early 1970s. Many of the worldвЂ™s best known automatic chronograph movements were developed in the arms race of the late 1960s. The origins of the 7750 spring from another famous name from the past, Venus, which became part of Valjoux in 1966. By the early 1970s, AUSAG included several watch brands, such as Certina, Edox, Eterna, Oris and Longines. Created in 1931, AUSAG consolidated many of the independent movement makers in Switzerland. The 7750 was developed by Valjoux, a legendary movement maker that was part of the giant ASUAG conglomerate.
