====== JLC 877 ====== **Calibre 877** 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 877 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 217 pieces. Calibre 877 runs at 28,800 vph and has 25 jewels. Calibre 877 was introduced in [[2003]] to replace the venerable [[JLC 124|Calibre 124]], which dated to [[1931]]. Development was started in [[1997]] with the release six years later coinciding with the 200th birthday of [[LeCoultre, Charles Antoine|Charles Antoine LeCoultre]]. It spawned [[JLC 876|Calibre 876]] a year later, which added a [[perpetual calendar]] module. Although Calibre 876 has continued in production, Calibre 877 was discontinued. ===== Applications ===== Calibre 877 was used in the [[Jaeger-LeCoultre Master Control 8 Jours Reserve de Marche]]. It was also used, in a 33 jewel version, by [[Officine Panerai]] for their [[Panerai Radiomir 8 Days]]. Calibre 877HG lacked the power reserve indicator and was used in special-edition [[Jaeger-LeCoultre Eight Days]] models. **Manufacturer:** * [[Jaeger-LeCoultre]] **Description:** * [[Hand-winding]] movement * 217 components **Functions:** * Hour, minute hands * Day/Night indicator at 1 30 * [[Small seconds]] at 5 00 * Date at 7 00 * [[Power reserve indicator]] at 10 00 **Data:** * H 5.3 mm * 25 [[jewels]] * 28,800 A/h * Power reserve 8 Days **Production period:** * [[2003]]- {{tag>Movements Manual_winding_movements Jaeger-LeCoultre_calibres Jaeger-LeCoultre_8_Days_calibres Double_barrel_movements}}
