Pam 243 movement issue

[perry563]

I see that my new noob 243 stops running. I wore it for only the third time several days ago and it told great time for 24 hours. Then I noticed it had stopped. I did everything I could for 2 hour to get it to run again...shook it to spin the rotor, wound it with the crown, tapped the case. It would run for a min or two and then stop. Finally I got it to run and layed it face up on my watch box...been running strong and on time since. What could be the issue?

I had the same issue with my 243, in my case the hairspring was the issue. After a bit of gentle pulling with tweezers to get it free the watch has been running like a charm for the past 6 months.
