Hi There, I am pretty new to the vintage watch scene but I looking at buying a vintage powermatic. I am not sure if its being tampered with would anyone be able to offer any advice??
Inside, the markings are as follows:
Serial number 770475
The inscriptions on the case back are as follows:
Cased and timed in USA by LeCoultre
Star Case Watch Company
10kt gold filled
There are a couple of what I think are service marks: 15061 and RD1525. Doesn't make sense to me though.
