The train wasn't moving smoothly. There was a problem with one pivot on the escape wheel that was not obvious. It must have been damaged in some way. No issue was visible but it started working fine after I burnished and polished it.
After complete assembly, the balance wheel isn't moving freely. Again, the pivots look OK, but I think the lower one is just too worn. I may have to obtain a replacement staff. It's getting hot today in the watch room, so I'll investigate this further tomorrow. This issue could be something else.
Elgin number 37912334 is a grade 519, 15 jewel, 8/0 size, made about 1939.
For those waiting for '26 watches to begin, this one is the last '25.
