Hello,friends.

This is AS 1802 serviced. Mainspring & Balance complete brand new. Movement works for less than a hour then stops. If I use a blower on the balance it begins to work again. Maybe the extra blue line shows up a clue. Any help?
 

AS 1802 caliber out of case.

UPDATE:
1)Minute wheel pivot worn out so too much end shake letting the wheel touch the plate ?


2)Escape wheel with teeth not good?
