The JLC 924 is a watch full calendar automatic movement from Jaeger-LeCoultre.

Calibre 924 was a 2005 replacement for Calibre 891, which was slightly smaller and lacked the moon phase and power reserve indicators. In 2013, Calibre 866 replaced Calibre 924 after 8 years on the market. 866 was very similar to 924 but lacks a power reserve indicator.

The 924 is an automatic movement running at 28,800 vph. It has 41 jewels and a power reserve of 43 hours. It is a traditional-looking movement with central sweep hands for hour, minute, and date pointer, and a subdial for seconds and moon phase. It also has windows for day and month at 9:00 and 3:00, respectively, and a power reserve indicator at 12:00.

Jaeger-LeCoultre used this calibre in the Jaeger-LeCoultre Master Calendar.
