Help please with identifying PAM 'spare' screw :)

[Theodad]

Hi all. Newbie here. Bough my first rep (PAM 111 V4) from Toro last year but for about six months it has been stopping whilst still about half wound. Ive just been using it anyway with a 12hr reserve. However it recently stopped fully.

Taking the plunge i took it apart to explore. I discovered that the main spring was holding tension fine, and ive given it a blow and a bang (that about sums up my level of watch mechanical understanding) and it seems to be working again..... trouble is i seem to have a tiny tiny spare screw (that i haven't removed myself) that fell out of the case....... i'm trying to work out if this should be there and has come lose or if it might have been the cause of the problem in the first case.

Any ideas what it is and how i can check to see if it has fallen out of my movement, or if i should just bin it!

Thanks in anticipation

Thanks for your reply Spanks but ive had a close look and both of those screws are still in situ. It must be from somewhere else. Any other ideas?

He was referring not to the two screws with the heads facing up, but where the millimetric screw would go into the swan neck -- perpendicular to those screws and against the arm of the regulator.
