Darwil Digital direct read jump hour, PUW 1560D inside - automatic with 25 jewels, bit of step up than usual pin lever Baumgartner movements found in vintage jump hours.
case is one of the usual MS Hydro Polyp cases that this manufacturer made for Stowa, Arctos, Meister Anker and few other german companies. Unfortunately, chromed and worn.
unusual for this model and for Darwil - it is not swiss made but german made, just another one of the variety of Darwils I have come across.
I also have a Solar Digital model on rehaul but different than Celletronic mentioned before.
