Hello, 

I have recently brought a seiko 7002 and fully restored it and freshly oiled it. 

I am now at the stage of trying to regulate the beat error / timing.

I have purchased one of those timegrapher app on my iphone to save on money.

I had the microphone on top of the balance yesterday and manged to get the beat error t 0.50ms appox. and the time average rate of -6 secs per day.

 

I was very happy with this for a first attempt.

 

However, after checking it a while later, the results were thrown out. perhaps this was also due to the fact i had the microphone underneath the cyrstal this time. 

 

The graph also doesn't correspond to the typical two parallel lines angled. Mine are dotted everywhere imaginable. i am also in complete silence by the way.

But ive seen someones elses like this with good regulation on the internet, perhaps its just the app?

 

Can someone more skilled please advise, because id really like to take this hobby up.

Always wondered if these Apps were any good? Have tried a few but some never detected and others hit and miss.

If the app worked before but not after the problem is with the watch. 

Anyway just like an hardware timegrapher the app needs a good microphone and stand  to work perfectly. The Chinese one cost about $75 plus few more for the powered cable. Not very far from $125 for the entry level machine.

I don,t have a timegrapher and can hardly be considered skilled, nevertheless, If you get good amplitude. I let the movement run for couple of days (for good lubricant distribution) , behaviour may undergo even more change.  

Check if dirt, tiny hair has got inside. Observe HS from the movement side under good light and magnification. 

How about  the MS and barrel?

Wind full manually, observe ?

      Balance spring fell out of regulator pin.

      Thank you so much, Hector and CJ. I appreciate the tech sheet and the video. Gasp, I think I will make the attempt. What's the worst that can happen? I think there may be a new balance complete in my future, though.  I'll update the post and let you know the result. R, Frank

      So here is the new base (v 2.1), I made it so that the base will fit over and swallow the stump of the hand pusher tool (or at least my clone of the tool), I also reduced the OD of the bottom skirt a little as it looked/felt a little large, here are a few pictures and the fake .pdf file which you need to convert to .zip once downloaded.   The cut-out seen on the below image on the bottom of the base should swallow the OD (40 mm, +0.1 mm tolerance) of the stump and the height of the stump 9.5mm (measured to 9.1mm, but rounded to 9.5mm) - let me know if this works for your tool.   Note, I think you may need to print supports for the new internal shelf created? Here is the fake .pdf for just the FreeCAD base file and 3mf files Modular Movement Holder.pdf Here is the fake pdf for complete set of the new base and ring FreeCAD/3mf files: Modular Movement Holder base and ring v 2.1.pdf However, I'm wondering how often you could use this feature, adding the dial usually increases the OD of the movement, so you would need a new (larger) adapter ring tuned to the OD of the dial and I wouldn't like to grip the dial in any kind of movement holder if It could be avoided for fear of damaging it. Maybe I'm misunderstanding you?

      Hi Frank, you have dived headlong into the deep end. Hairspring work has to be the scariest thing a newbie has to tackle. Your hairspring appears to be bent and just putting it back into the regulator would not allow the balance to work properly. It might start oscillating but the performance would not be good. The proper thing to do is to unstud the hairspring, remove the hairspring from the balance, reinstall the hairspring on the stud carrier, reshape the endcurve and centre the collet to the balance jewel hole. This challenge would either make you or break you. Hope that you will be able to fix your watch. Welcome to the world of watchmaking.  Watch this video. It think it'll give you an idea of the task ahead. From your 1st photo, I think you have a etachron type stud. Let me see if I can find a video on how to remove it from the arm.

      Have read of the Tech Sheet attached on the balance section page 12. It may be bent but until you reposition it back in the regulator pins you'll never know. Cheers CJ 4R35B_4R36A.pdf

      Aloha All, My Seiko 4R35B movement stopped working today. Upon closer inspection, it looks like the balance spring came out of the regulator pin. This is my first time working on a balance. Any advice on how to get this spring repositioned (back to normal)? I'm pretty sure that while adjusting the beat error on this movement, I must have turned the stud (I didn't even know they turned), and the spring eventually fell out.  Will the spring go back to even spacing when it's back in the pin, or does it look bent? Thanks, Frank
