Reconvilier 12

Description

The village of Reconvilier is located in the swiss Jura. Since 1853 (with interruption and revival in 2006), the manufactury with the same name produces watches and movements.

The Reconvilier 12 (later renamed as caliber 2310) shown here dates from the 1940ies and is a 10 12 ligne pallet lever movement, which reminds of the common movements of that time, like for example the AS 676.
