This was my Mom's watch and after reading up on how to figure out the year it was made etc.
I also found some interesting writing on the inside of the back cover curious to know what it is?
Can't seem to find the name of the watch.
On the movement N4, 5BD
On the inside of the back cover which is 3642
and with the most magnified setting on my loop I found this on one side that had been engraved G361641488RS
and the other side G683011879RS the R and S look to be more personalized with a slight cursive loop in R
