In late fifties Citizen developed it's own alarm movement based on AS1475. Citizen's movement is a bit bigger and also the bridge is notably different. First models had 17 jewels, they were marked 980* and 981*. Later, a movement with date complication was added, code of the movement was 3100 or 3102. Those movements had 19 or 21 jewels. In the development phase of this movement, version 3ADJ without date can be found as well.
Identical to AS1475. Please see A.Schild submenu. For the models with the date complications there is no quick set date, only passing midnight changes date.
