The JLC 925 is a thin automatic watch movement with moon phase from Jaeger-LeCoultre.

The 925 is an automatic movement made up of 246 pieces. It runs at 28,800 vph, has 30 jewels, and a power reserve of 43 hours. Unlike most Jaeger-LeCoultre movements, Calibre 925 is unidirectional, winding only in the counter clockwise direction. It features central hour, minute, and second hands as well as a 6:00 subdial with a date hand and moon phase indicator. The moon phase is adjusted via a recessed pusher at 8:00.

Jaeger-LeCoultre currently uses this calibre in 1 watch, the Jaeger-LeCoultre Master Ultra Thin Moon 39.
