The movement shown is generated in the 15 Jewels version. There are used saphires instead of rubins.
Again, I find it difficult in some caliber allocation. With the above list I tried to provide some clarity on the different caliber and their designations.
The movements were produced at the same time with or without divided wheel bridge. There are versions with 7, 11, 13, 15, 16 and 17 jewels.
There's caliber Junghans J80 with various imprints on the bridge: J80S; J80M (was probably Meister).
