Poising Question

[fuse63]

Hello everyone,

I have a question on poising a watch that does not have balance screws. I received a watch for service and the balance wheel has drill holes from the last watch repair person who poised it. My question is is that it is running fast now and I was wondering how do you slow it down.

 

Thanks

Hello, is there any way to get some info about the watch. For example movement name and number etc. Also after servicing what kind of readings are you getting on the timing machine? Thanks

Yes its a Universal Geneve 541 17j womens watch. Its running really fast, +140. I have fully serviced it, it has great amplitude.

What about the timing in different positions? Also what is the current position of the regulator, is it in the middle?

140 is dial up, i will get the readings for you a little bit later and  yest the regulator is in the middle

It would help to have a picture of the watch preferably located over the balance wheel. Then did you attempt to move the regulator to slow the watch down? Then is this a poising question or regulating question?

You might try to fill the holes with some solder. Just an idea, I never tried it. I would remove the roller with the impulse jewel, though.

Only if you don't have any other choice!

I would leave the regulator  to one side then messing with the balance.

 

What is the Delta on it?

Ĵohn's question is interesting and technical, are you just after accuracy, timing? Or percision? which involves poising ..

Soldering if followed by turning the wheel on lathe to remove the extras can produce descent results, filing off  the extras manually is ruining the wheel.

Some designs,  I hear rolex for one ,  times as poises., for split second accracy which requires near perfect ballance to match excellent h/s. 

If the ballance wheel has no screws, poising and timing are two seperate tasks.

Fully serviced means you took demagnetisation too, right?

[Nucejoe]

Examine the h/s for proper functioning. If h/s is okay and still fast at it's maximum lenght. Replacing the h/s with one of  larger length , is the shortest route to accuracy.
