Here is a movement from a Paul Buhre watch from the 50's. Did PB make their own movements or buy from an outside vendor. If from a vendor, can anyone identify this?

thanks

 

I’m sorry, but you really can do your own homework on this. Would take 30 seconds.

 

To learn about the import codes? Longer than that. KOS, it looks like.

How precious.

How would anyone who is totally new to even know what a f---ing import code is!

 

I see someone was disinvited. Sorry to see that, but as one sows, so shall one reap.

 

Apparently, my google-fu is weak in this regard. Various combinations of Paul Buhre + movement came up empty.

 

Disinvited how?

 

My mistake. You put "Banned" as your tag line and I took it literally, because why would I not?

 

Felsa made the Bidynator movement. Famous caliber.

Import code is irrelevant to the movement manufacturer. KOS is just the Paul Buhre US import code.

 

Huh. Thought it was more specific.

 

Hello @arturo7, "Bidynator" automatic movements were made by Felsa, and were the first successful bi-directional automatic movements -- i.e., the rotor/oscillator was capable of rotating 360 degrees in either direction, as opposed to a "bumper" automatic. The first Bidynators were introduced in 1942 and were marketed until 1968, I believe. The movement should have the Felsa hallmark and a model number, which is typically located beneath the balance wheel or directly to the left or the right of it. The model number should help you narrow down the production date. You might find the following link helpful. Cheers and happy hunting! Bidynator - Chronopedia

 

Thank you!!

 

DanS and Allwoundup saved the day. I thought this thread was going to go down the drain and was ready to call @Walrus for some backup.

 

Happy that I could be of some assistance. When you identify the Bidynator model number go to the following link and enter either Felsa or Bidynator and the model number into the search box to find additional information. Cheers! bidfun-db Archive: Watch Movements (ranfft.de)
