Problems With The Balance Wheel

[Rhytox]

Hi

 

I'm kinda new to the whole "watchmaking scene". I started off with taking apart a tissot and a seiko.

I seem to stumble upon the same problem everytime:

When I reassemble the balance wheel onto the main plate, it seems to run slower.
Also it tends to stop when it's held sideways (sometimes even when it's flat).

(I tried to upload a video, but apparently I don't have permission to do so)

I also tried to search this forum but haven't found anything similar.

Can anyone help me with this one please?

 

Great forum, I already learned a lot here!

Thanks in advance

One possibility is you're bending the balance staff pivot when you're disassaembling it...

If the balance was ok before then it could be you are damaging the balance staff, contaminating the hairspring, fitting the balance but seating it incorrectly into its jewel/s. or not lubricating the jewels correctly.

I concur with what was said here. Welcome to the forum!

I think i solved it, the balance staff was slightly bent.
