In 1969, Jaeger-LeCoultre introduced an improved movement, Calibre 916. Known as "Speedbeat", it featured 28,800 A/h oscillation for greater accuracy and resistance to motion. Additionally, the winding rotor rotated completely around a wide hole, allowing the case back protuberance to be struck at the center.
