The caliber Junghans J56 seems to have been made not only for Westclox because the company Diehl, who was then owner of Junghans also has used the movement.

The Diel version shows a speciality: the balance bridge is not united with the motherboard, but is screwed separately as a

bridge. Further information on cooperation with Westclox: The Westclox-Mystery
