====== JLC 923 ======
**Calibre 923** is an [[automatic]] [[dual timezone]] watch movement from [[Jaeger-LeCoultre]].

Based on [[JLC 899|Calibre 899]], Calibre 923 incorporates many changes. Most obvious is the [[world timer]] mechanism, which functions more as a [[dual timezone]] readout than a true worldtimer since only a few timezones are visible at once. Also different is a uni-directional winding mechanism similar to the [[JLC 975|"Autotractor"]], which is more efficient, with ceramic bearings. A larger barrel provides 45 hours of power reserve, and the mechanism is more efficient thanks to re-contoured gears. Additionally, fine adjustment can be made with four regulator screws.
