Calibre 878 is a watch movement from Jaeger-LeCoultre in the "Eight Days" family.

Like all of Jaeger-LeCoultre's "8 Days" movements, Calibre 878 uses dual barrels 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 276 components, making it the most complicated of the family. Calibre 878 runs at 28,800 vph and has 35 jewels.

Calibre 878 is a development of Calibre 877, launched in 2003. It is closely related to Calibre 873, Calibre 874, Calibre 875, and Calibre 879.

Applications
