Omega 10033272 D Calibre 30scT2

Old balance staff glued into the balance staff.

Hole in the balance wheel is oval.

The donor balance wheel.

The balance wheel is correct, but it is 1000 seconds + to slow.

The hairspring collet needed tightening to fit the balance staff. And I replace 4 balance screws, with smaller screws to reduce the weight.

After testing that the balance is about the correct weight, I now remove the hairspring to poise the balance after best effort;)

Rest of the movement looks good.
