The PUW caliber 1361, a 25 jewel mens’ size bidirectional selfwindig movement differs from its predecessor, the PUW 1261 only in a few details, mainly on the dial side.
It’s not sure, that on the specimen shown here, the balance and balance cock are original, since there’s no moveable hairspring stud, only a two-leg balance and there are two different types of shock protection systems used: KIF Trior on the cock and KIF Satellor on the plate. So, maybe, the balance and the balance cock are replacement parts, which originate from the 1260ies series.
