Install Balance Wheel

[Geo]

Be careful.

Remove all tension from the spring first by using a screwdriver on the ratchet wheel screw to allow the spring to slowly unwind while you hold the click out of engagement.

Remove the click and click Spring.

Remove the balance and escapement lever.

Now use a watchmakers blower and puff air against the periphery of the escape wheel. If everything is as free as it should be, this will be enough to drive the complete train assembly.

Any stick spots or sluggishness is easy to detect using this method. Every time I assemble a movement, I do this before fitting the escape lever and balance.

Thanks guys!!

I did what you tell me and now it seems to work. But....it's very unstable . The first time I made it work it stopped only after one minute. I gently push the fourth wheel and now is running. It's about 30 minutes now.
