Calibre 916 (branded “Speedbeat”) was an automatic alarm movement from Jaeger-LeCoultre.Introduced in 1969, Calibres 916 replaced Calibres 815 and 825 in the Jaeger-LeCoultre Memovox range. This calibre went out of production in 1978 but was eventually replaced by Calibre 919, introduced in 1994. A total of 7,731 watches were produced with Calibre 916. There were two notable features of Calibre 916

1. It was the first Jaeger-LeCoultre alarm calibre to use a high-speed 28,800 A/h balance, giving improved precision.

2. It was the first ever automatic alarm watch with a free-rotating rotor, as opposed to the bumper movements produced previously.

As in other Jaeger-LeCoultre alarm calibres, the alarm hammer struck a protuberance on the back plate, making a distinctive buzzing sound.
