I picked up this 1959 Bulova 11ACC on eBay last week for $30.

The movement was thoroughly rusted into the caseback--first time I've every used WD40 on a watch. 

Finally got the movement out of the case--got as much surface rust off the parts as possible (and chipped the intermediate wheel in the process 😞 ), cleaned it, straightened the sweep second hand pinion a bit (didn't want to tweek it too much), and reassembled.  Keeps +/- single digit time in all positions with pretty good amplitude (270-220). Since I re-used the mainspring, I'm going to call it a win and move on to getting the case/dial and hands in order.
