I've been working on an AS 1187, recently cleaned and lubricated it but no matter what I do, the rate is too high. In the attached photos the movement has the mainspring it came with, and it's older, but I have gotten similar results on the timegrapher when I put in a newer mainspring I got from Otto Frei, MS -711K. Here's what I've done thus far to no avail: After cleaning the entire movement I cleaned the balance assembly in One-Dip End shake seems pretty good from what I can tell, but I'm not very experienced at making those determinations Banking pins look fine Checked where hairspring is running between the boot and curb pin. Seems fine. Curb pin seems fine (straight) Inspected all jewels on bridges, pallet fork, etc. All look good. What else should I do? Thanks! -
Its based on Seiko 7001, go on to alldatasheet.com . I think its a combined set mech. You likely to have knock the set lever out of whack. Rgds -

1) flat jewel for wheels: picture shows a jewel with oil sink. Straight hole. Not hole 8 or 9. 2) balance jewel, olive hole: picture shows a domed jewel without oil sink. B + sizes. 3) flat jewel, olive hole: hole size 8 or 9 only. Frank
