Today, self-winding (or automatic) chronographs are quite common. Omega created a prototype of one back in 1948 but later abandoned their production plans. Over 20 years later, two companies and one collaboration would finally make it to series production: Seiko, Zenith, and a joint venture between Heuer, Breitling, and Hamilton. These manufacturers all introduced and launched their automatic chronograph movements in 1969, and this watch style would quickly become very popular throughout the industry.
