Calibre 814 was a manual winding alarm movement from Jaeger-LeCoultre.
Introduced in 1953, Calibre 814 joined Calibres 489 and 601 in the Jaeger-LeCoultre Memovox range. Essentially an improved version of Calibre 489, Cal. 814 would be produced until 1964, when it was replaced by the popular Calibres 910 and 911. In 1956, Jaeger-LeCoultre also introduced an automatic version of the Memovox, using Calibres 815 and 825.
Calibre 814 was also available with Parachoc shock protection as Calibre P814 and with Kif shock protection as Calibre K814.
As in Cal. 489, the alarm hammer struck a protuberance on the back plate, making a distinctive buzzing sound. Even if the alarm was not wound, the hammer rattled freely against the protuberance.
