Hello, I'll do the cleaning and some assembly today. Hopefully, I'll upload some pics later today. I have two questions: 1. lubrication of the "driving gear assembly for ratchet wheel" The manual only prescribes lubricating the clicks and the pinion with grease (and the pivots of course): But this guy also lubricates another point (https://youtu.be/LmHqj5RMXqk?si=Mg5D7U0DEt_xf_MK) What do you think? 2. Cleaning and lubrication of rotor ball bearings. From the service guide: a. Would you follow this cleaning approach instead of my usual L&R No111 (ammoniates watch cleaning solution) and L&R No3 (watch rinsing solution, two cycles)? b. Would you use Moebius 941 for the balls?? First time I see this in a manual? Normally, I'd either use 9010 or Lubeta V106. What do you think?

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!

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

That’s a fair point and is what’s stopped me from making a more concerted effort to open it. Since it’s got an SW200 in it, I was thinking of getting an Invicta diver with the same movement for $200 or so and messing with that first. I was thinking that the SW200 fine regulation screw would be easy to turn to slow the watch down a bit, but maybe it’s easy to break the movement even doing something simple like that.
