1940s Helbros invincible that I just finished (my first attempt at watch repair)

[NathanM]

Got this watch off eBay for 25$, would run for a few seconds then stop. Once I had fully disassembled it, I inspected all of the pivots, trainwheels, jewels etc to look for signs of damage. Found none so assumed it just needed to be cleaned. I cleaned the watch parts in an ultrasonic cleaner doing one cycle with a detergent, a second with a solvent, and a third in 99.9 % alcohol. put it back together and lubricated and its running great, Seems like it just needed to be cleaned and lubricated in order to run well again.
