Bought this watch for less than $50 at a pawn shop a few years ago. Looking to learn more about it.

-I see D63.202 on the back. Is that a reference number. Google didn't find much.
-I have found a couple similar models but in gold (white and yellow) and without a date at 6. The descriptions say they are from the 1960's.
-Crown shows "JJ".
-Back says watch is stainless steel.
-Runs about 2 to 2:30 minutes fast a day. So I usually set 5 minutes slow and then wear for 2-3 days every once in a while.
-What is the approximate age and value?
-Please provide any other information possible
-If anyone knows of a good place in the Northwest Suburbs of Chicago to get something like this services that information would be appreciated too.

 

Jules Jürgensen was a watch reseller/ rebrander that was popular among better department stores in the US from what I could find in my research some time ago. What that means is that they would contract with buyers from department stores and assemble the watches to spec (or the buyers would pick from a catalog) and brand it with their logo. Most of the JJ’s I have encountered are well made with good movements (Eta or Felsa usually) and are nicely finished. It’s not uncommon to see identical looking watches with a different brand and movement- but same case and dial.
As you guessed, it dates to the mid-60’s. As for value, ones like this hover around $100-150 in excellent shape, so you did well.
