I still think it’s a Favre base caliber, but the stamp on the main plate is intriguing, to know if there’s a different ebauche supplier.

As far as who supplied to Gruen, stay tuned. The exact sn placement/orientation/font on this P. Ditty is pretty convincing, but I just got another EP grade Gruen caliber that I think is Favre in house—close serial numbers. Let me get plate pics for it


My two caveats:
1) I'm wrong many times a day --just ask my wife!
2) Always seeking to learn more
