The Citizen 3102 watch movement features a pin lever mechanism and an indirect minute hand friction clutch on the barrel. Additionally, it incorporates a stem mechanism without a setting-lever spring. Variants of this movement are available with or without a separate barrel bridge. It is a manual wind movement with a sweep second hand and a date function that can be adjusted by changing the time from 21:40 to 24h. This movement was predominantly used around 1980.
