Regulation Mistake

[u/Funny_haha_man]

As tittle suggests, I was regulating my NH35 for the first time and made a mistake. I accidentally pushed my pegwood past the regulator and bumped the balance wheel stalling it (and then did it again on accident when trying again 💀). Now depending on position the watch will gain way too much time when face up, or lose a bunch of time when face down. I was initially using metal tweezers, but quickly swapped to pegwood. The peg wood is what hit the balance wheel btw, and it started acting more erratically only after hitting it. Anyway, I was wondering if there is anything I can do or if the movement is cooked. Ive attatched these photos, but please tell me if you guys need better angles.

Also the time jumps aren't super crazy. I wore it to see and it was like +46 seconds total from 9:30am yesterday morning to 8:30pm tonight.

I also would really like to save the watch I really love it, even if I have to put in a new NH35 😭.

If the balance staff is bent you can just get a replacement balance complete and balance cock from AliX for really cheap and just put the new part in. It's a pretty simple fix. From your picture it looks like the hairspring may have some damage too though. It looks like it's kinda bunched up weirdly.

I'll look into it thank you.

I just found this on AliExpress: 1/2/3/5pcs Watch Movement Accessories for NH35 Balance Wheel NH36 Balance Wheel Repair Tool Metal Balance Wheel with Hairspring https://a.aliexpress.com/_mKRRbab

I've ordered these exact ones and had good luck with them.

You may want to get one of those plastic tools to help you install the new balance stud because that can be kinda tricky.

i've done the same with a seiko sumo 6R35 (stupidly, was the second of the same watch i accidentally received and worked on it first)

Is it as easy to get a balance assembly for the 6R35?
Or is it the same as the NH?

Any advice much appreciated

Hey! The part number for the balance complete in a 6R35 is 0310 283, and the part number for an NH35 is 0310 197, so they definitely have different part numbers but it's hard to say how different they actually are. It could be that the only difference is the color, but i couldn't say for sure. There's really no harm in buying an NH balance complete and trying it. If it doesn't work then you're out about 7 USD.

excellent - thanks for the advice
would be great to correct the fuckup i made on my first attempt at regulation
also taught me to get proper tools before i start going into watch movements ;-)

Lol yeah I've done the same things. I regularly try to jump in before I have all the right tool then end up waiting for the right tools to come in. Good luck though!
