This rare variant is marked on the movement plate with J96 7, the 7 is in this case slightly offset and larger. The Junghans star on the movement plate (8-pointed) inside is marked with the "J" and over "UNGHANS".
The movement of the Caliber Junghans J96 7 (hence the caliber note 7) has 7 jewels and has a stone pallet lever unlike the standard movement (Junghans J96), which has only 4 jewels and a pin lever escapement.
Unfortunately, the silver (presumably) of the main plate is largely removed.
