I am very happy. Since one week I am working with this movement. After solving one problem I found another one. In total 5 different problems.
Since 30 minutes the movement is working. I am watching now since minutes the balance moving.

I loss the time notion in these circontances:
When fishing at sea.
When piloting an helicopter.
When gambling at Las Vegas.
And the new one, when restoring a watch movement.
Nice day for everybody.

We should document the 100 years of design evolution of Waltham 3/4 plate movements from this to to the "final 16s" pieces.

Real fundemental changes could probably be counted on the fingers of one hand.
