I think it is going to be very difficult to find a NOS movement from the 1950's. Roland Ranfft indicates that it may have been used in Gruen watches. So look for donor watches on Ebay if replacing the movement is critical. However, you should consider rebuilding the movement unless parts are missing. It's a basic mechanical movement that with some cleaning and adjustment should run for another 50 years.Hi,
I want to restore the Lip Dauphine Technic that my father given to me.
I'am looking for a R166 mouvement (Jeanbrun 26D) in NOS condition.
According to my Bestfit books, Gruen 515SS is a Jeambrun 23D.Roland Ranfft indicates that it may have been used in Gruen watches.
