====== JLC 977 ======
The **JLC 977** is an [[automatic]] [[dual timezone]] movement from [[Jaeger-LeCoultre]].

Introduced in [[2006]] with the [[Jaeger-LeCoultre Reverso Squadra Hometime|Reverso Squadra Hometime]], the Calibre 977 was one of the first [[automatic]] movements used in a [[Jaeger-LeCoultre Reverso|Reverso]] watch.

The [[Jaeger-LeCoultre Autotractor]] family of movements is often referred to as "the 970 family", and Calibre 977 should be included in this family, since it includes the same elements as the familiar [[JLC 975]]. Calibre 977 is very closely related to [[JLC 970|Calibre 970]], used in the [[Jaeger-LeCoultre Reverso Grande Automatique|Reverso Grande Automatique]], but that watch adds a [[big date]] complication.

The JLC 977 is made up of 234 pieces and features 29 jewels. It runs at 28,800 vph and has a power reserve of 45 hours.
