(Re-)Install Balance Wheel On Eta 2824-2

[watchill]

Hi together,

I have to replace the balance wheel on an ETA 2824-2, but it just won't fit in properly and get the movement run.

Can you help me out please? What is the proper way to do it?

I found this video on youtube (min. 20:52) but I can't manage to do it...

Welcome to the forum Watchill.

Regarding your problem:-

First, make sure you have at least two or three turns on the mainspring.

Now remove the balance and ensure that the escapement lever flicks sharply from side to side when touched very delicately with a dry oiler. If it does then you probably put the balance wheel in the wrong position regarding the escapement lever.

When you look down on the escapement lever; if the lever is resting to the right, make sure that the roller jewel on the balance is rotated further to the right than the end of the lever as you locate the balance pinion in the lower jewel, if you do this, it will catch the end of the lever when you rotate the balance cock to the left as you locate it on the main plate. If all is well, the balance should start up as you locate the cock on the main plate. The reverse of this is true if the balance lever is initially resting to the left.

I hope this helps.
