Vintage Kiefer Automatic watch Service Cal. Felsa 4000 Bidynator

Hi guys, today for you a service of a beautiful watch bought a few weeks ago for my collection, purchase price €35. A nice 1960s Kiefer with Felsa 4000 Bidynator caliber, a very beautiful mechanics. Watch case diameter 34 mm, the watch arrived working but as you will see from the video the parameters were very bad. After the revision the watch started working very well again, it was not necessary to replace the mainspring which was still good, i replaced the crown because it was too thin, with my giant fingers I couldn't wind the watch.
Even with little money you can have great satisfaction!!!!!

I Have a Kiefer Watch. Do you know any of the history behind the brand? I have had trouble looking

[@watchrestorationchannel1061]

Me too, but I think it's a micro brand from the past. It has no collecting interest.

How did you open this mainsprimg barrel? Just unscrew the top?

That's right, the wheel is grafted directly into the barrel arbor.
