**Calibre 873** is a watch movement from [[Jaeger-LeCoultre]] in the "Eight Days" family.

Like all of [[Jaeger-LeCoultre 8 Days|Jaeger-LeCoultre's "8 Days" movements]], Calibre 873 uses [[dual barrel]]s to power the movement for eight days. Unlike the [[Jaeger-LeCoultre Duomètre]], however, these barrels are integrated into a single power source rather than being split among various complications. It is a [[hand-winding]] movement made up of 213 pieces. Calibre 873 runs at 28,800 vph and has 25 jewels.

Calibre 873 is a development of [[JLC 877|Calibre 877]], launched in [[2003]]. It is closely related to [[JLC 874|Calibre 874]], [[JLC 875|Calibre 875]], and [[JLC 878|Calibre 878]].

===== Applications =====
Calibre 873 was used in the [[Jaeger-LeCoultre Reverso Grande Sun Moon 8 Days]].
