The JLC 844 is a watch movement from Jaeger-LeCoultre.

The 844 is an extremely compact movement used in the Reverso Duetto models. It is a hand-winding movement made up of 100 pieces. It runs at 21600 vph, has 18 jewels, and a power reserve of 40 hours.

The JLC 844 lacks a second hand and drives a second face with the same timezone as the front. It is not a dual timezone or GMT movement, unlike the similar JLC 854.
