Hi, I was looking at this cal.265 for sale on eBay and saw a reference number on the outside of the case. Does that mean it is some kind of an unoriginal case? Btw, the dial looks original but Not really sure. Have a happy new year! http://www.ebay.com/itm/141323315495Purchases made through these links may earn this site a commission from the eBay Partner Network
Short answer--yes. However, this was common is 1950's Argentina. It does reduce the value of the piece substantially. Hope this helps, gatorcpa
I think it's a fake or custom case: doesn't properly fit the dial and an improper Swiss-style 18K hallmark.
Ok, so I'll stay away from that watch and keep looking for the right one. Thanks a lot for your expertise guys.
Actually TWO marks on the back. Reference number of some sort and an 18K mark. Pretty typical South American type case.
