Took me 5 seconds to search for one…lots of places selling generic versions of these…

If you are considering doing this yourself, I would strongly advise against it. Even if you have done something similar on say a Rolex, this is very different, and trying this without fully understanding what you can and more importantly cannot do when moving the balance, you are very likely to damage the escapement.

I have a Little experience in servicing Watches. Can you explain me how to do it? Or would you say that even a hobby wagchmaker shouldn‘t do it?

Well the co-axial escapement has a different sequence than a regular escapement - if you move the balance wheel in the wrong direction at the wrong time in that sequence, you will damage the pallet fork. You can't just turn the balance wheel any way you want at any time like on a lever escapement watch.

I don't even recommend that watchmakers who have not had the proper training from Omega work on these...but many do and I get panicked emails when they need help getting bailed out...

Hey, you do whatever you feel is right...it's your watch so no one is stopping you.

Yes Thank you for your answer. It was just a technical question if it is a working idea to Hack the Balance and Turn the screws. In that way i shouldn‘t damage anything.

The hack doesn't really hold the balance particularly securely in most movements that I've worked on (note: not an 8400). So I don't think it should be the reassurance that you're hoping for.

Turning the screws is already dangerous enough as you always risk damaging the staff if you're not careful, adding the additional risk of not being able to rotate it in the 'wrong' direction without causing damage is... scary to me.

As someone who knows a BIT about coaxial movements, I would absolutely not be willing to mess with the balance.

Let's just say this is not an approved method of accomplishing this from Omega...but if you are determined to do this let us know how it works.
