You are exactly right. Now the harder work begins - to open it up and put it back together, without injuring the balance spring (hopefully). Cheers, Cazalea

Both mildly decorated; Stowa with swan's neck adjuster

I've decided to get right to work, as a patient who is handled quickly and carefully has a better chance for survival, don't you think? I removed the back cover. Notice the blued screw near the word SWISS is mostly undone. The adjusting arm has fallen off...  

Wow you really know you stuff Way above my pay grade. Bill

With a few annoying obstacles along the way, I pulled the balance cock, replaced the stud holder and adjuster, and reinserted the balance into the movement. I thought I would try a new iPad-based timing meter, so downloaded the software and ran some tests...  

Here's the ladies tiny Jubilee watch bracelet and the gunk that came out of it! ...  

I think I found it in the app store. Is there anything one needs to know to use it? Or does it just work?

But if you just want to see how your watch is performing, it just works. You do need a quiet room and you need to have the mic directly over the escapement- so it‘s nice to have a transparent caseback. Cazalea
