In the 1950ies and 1960ies, this movement was made in the Czech Republic. The exact caliber
name is unknown to me, since on the one hand, the main plate is marked "0111", on the other hand,
you can read in the
literature,
that it was named caliber 52.
The construction fascinated by bevelled angles and a breguet-shaped hairspring.
