Hey guys sorry if I'm abusing the bandwidth by adding so many photos but I wonder if I could get pointed in the right direction. I'm fairly certain the issue is the mainspring. I don't know what else might cause this. The movement has been clean and I have played with the hair spring a bit to get it to run close to zero but any movement from where its at one way or the other and it swings wildly faster or slower so I know that is something but that's for another thread. Here I show timer reading for DD, DU, Crown at 3, 6, and 9. The screen is about 1:30 long. You can see that the lines look pretty darn nice, the Beat error is okay, but the rate is allover, in each position? My thought is it has to do with the mainspring either still being dirty, or it hasn't been oiled well enough? So before I strip it back down again just to put it back together I'd like either confirmation or another suggestion. Sitting fully wound on my desk dial up it is still right on from where I left it over night. The order is a bit mixed up and I my have failed to upload all to PB which is.... The first several are dial up and dial down and you can see the swing, I then get some pretty poor numbers when the crown is at different positions 3,6,9, I don't think I did 12??? All of these were taken after I had gotten it as close as I could to zero dial down. No adjustments have been made since. Dial and hands were on and it was cased with the back off. It has been fully wound and let to run down several times before I started top make adjustments. As always thanks in advance,

Can you wind the MS every 5 seconds back to where it was to provide the same power?
My guess as a total newbie, would be incorrectly cleaned escape wheel or a bent pivot somewhere. Have you demagnitised it aswell?
Interested to see what others say and ultimately what's up.

Could be a worn jewel or a bad escapement wheel as it wobble. As you have different readings in different positions i think it could be a worn jewel or pivot. Could this help? Wow thanks for these this make a bunch of sense! Okay I get that I may have gone a bit sloppy with the 9010 on the pallet that's gonna take more practice and I think that is giving the little ticks in the lines. Since the rate changes are not regularly repeating I'm think gear train is okay. The closest thing would be irregular rate so amp is insufficient while its low other then dial up and down and even flat its not great I'm wondering then if its just not got the drive it needs from the mainspring? I'm thinking of taking another off of a donor and giving that a try...I just hate "Changing parts" with others that are unknown. Thanks for the comments guys

Why is this in the non Japanese section small?! Is it the Made in China timegrapher?

Todd, is this the 1686 from the other post? I would for sake of elimination demag it first. I just finished a 5606 today, and the rate was wild slow, and pretty low amplitude. I don't know exactly how magnetism affects a watch (other than the hairspring), but in this case the hairspring was perfect, and I was pretty bummed. I ran it through the demag and the rate flat lined and the amplitude jumped by 80 and it is running perfect. Also, do you have an adjustable stud carrier? There is still a lot of beat error in those graphs and that will hit your amplitude. Your pictures look most like the last scenario that Rogart posted, but I'd take out those 2 easy ones before you break it down again.

Your pictures look most like the last scenario that Rogart posted, but I'd take out those 2 easy ones before you break it down again. Yep the 1686, each time I have had to demag it was because the watch was running way fast and wouldn't slow under adjustment. I don't think I can mess with the beat on this, as the Stud is fixed. And I rather not mess with the collet. I swapped the adjustable seen in the other thread early on when it was all snowy and running 600+. All but one position does the BE rise above 1? Over 24 hours dial up on the desk and its still running fine....I always thought less then 1 was acceptable. I know we want to get it as low as we can..but... I think I'll redip the balance with the adjustable carrier and rebuild another Mainspring if running it over the demad doesn't get it closer. I'm near certain I ran it over before I broke it down as good practice so screws don't stick while disassembling but I may have spaced it this time. As I type I know I didn't demag that donor balance so you may have nailed it. I'll try it in the a.m. and put it on the timer after work to see. Thanks for all the replies

I know I'm not adjusting it to be a clock but came in this morning and before I ran it over the demag I check and in 13 hours was fast about 3 sec from my phones stop watch laying dial up?...Ran it over the demag just in case and have left it dd until after work.
