JLC 854/1

The JLC 854/1 is a mechanical watch movement from Jaeger-LeCoultre.

Closely related to the JLC 844, the 854/1 adds the ability to drive a second face on the rear of the case in the Jaeger-LeCoultre Reverso Duoface.

The 854 was introduced in 1994 with the original Reverso Duoface. It originally included a small inset corrector to advance the GMT function, and watches came with a "stylus". The 854/1 was introduced with the "updated version" Reverso Duoface and includes a large square button rather than the small pusher.

The calibre 854/1 contains 180 parts, including 21 jewels, and has a frequency of 21,600 vph (3Hz). It measures just 3.80 mm in depth.
