The mailman drop of a package with this.

This was in the red box so I guess the sender want it in place.

So we have to put it at the operation table.

Pullout a few things.

Try to find something for the crystal.

And press it out.

There we go with the old one.

And the new one.

In place.

Back with the crystal.

Looks good.

Back with the movement.

And the bezel to get the final result..
