That's neat. A 2 to 3 day movement is impressive, anything that can do that has to be specially designed.I just fixed a wind-up watch that I bought off of a street vendor in St Petersburg Russia back in 1995.
It quit working about 5 years ago. Since it's a winder, I never popped the back off of it. I did that this weekend. I gave the flywheel a nudge and a gentle shot of compressed air and it took off running.
So cool! It's almost a sweep second hand, and will run for 2 or 3 days on a single wind.
For $15 bucks, I'm impressed. I was hoping that it would last a year before it fell apart. It lasted close to 20 before it stopped.If I would have opened it up back then, I'm guessing that it would have kept going.That's neat.
