It's a guess: could it be a kind of Carolyn ??
EDIT: 2012.08.29 Changed from Carolyn to 1929 Prudence
In reply to Yes, Prudence. Good work Will by DarHin
Thanks for the complement DarHin, but it was actually Mark and Lisa (and others) who had been discussing this in an archived thread, I just stole their thunder, so to speak.
I'm not sure if the watch owner can "update" the record to change to Prudence since the new review/publish SOP. Willem, if you can't let me know.
Trying to read what is on the inside case back?

This is very good searching......
I'm deep impressed.
Thanks!!
I do'nt know how to update the item from Carolyn to Prudence.
If you can do so, please do!
Hi Willem, groeten van een landgenoot. Can you confirm the date code on the movement is a shield and not a small square? Bij voorbaat dank!
Kinda looks like a square date code....
Also noting a six digit case serial number. The last digit appears to be left out.
