Job Number 170010

This is a nice Waltham, 18 size, 17 jewel, P.S. Bartlett 1883 model.
This watch has the older style English lever escapement. The action is tangential to the escape wheel.
On initial assembly, the balance was sluggish dial down. Everything had seemed OK and the problem was not immediately obvious. But using higher magnification on the lower pivot of the balance staff I found just the slightest unevenness.
It might have been bent, just the smallest amount, or it might even be a manufacturing flaw. The irregularity was so small that I wasn't even really sure I was seeing it. I put the entire balance assembly in a balloon chuck and get the lower pivot a little touch and finish with a bell metal burnisher.

Problem solved.
