Picked up a nice 1965 date 7619-7010 25j Sportmatic Deluxe at a yard sale over the weekend for a great price. External it is in very good condition however when I looked at it, did not have anything to open the back with me, I noticed it made a clunk when rotating it front to back. I figured, oh well, the price is worth the risk, figured that the counterweight may have broke loose. Got it home an opened the back and everything was very clean but noticed a small screw wedged between the rotor and the case. Removed the screw wound it a few times and presto she works, keeps good time, day and date work correctly.
Going to take it to my watch guy for an overhaul since I was looking to make it a daily wearer. My question for the forum is how big of a problem do I have with front to back clunking and where might the screw have come from?
Thank you.
