Watchrepairology 1.01: using a mainspring winder. Automatic & handwinding springs.

Using a K&D mainspring winder - hand-winding & automatic / slipping bridle mainsprings. PSA: This video contains sub-optimal levels of editing, namely, none. No script, no planning, no real editing, nothing. Same for the sound - I forgot my microphone so if you can hear *anything* count that as a win. Even if that "anything" is tuneless humming. I did pump up the volume though. YMMV if you choose to blow part of your life on this. No Refunds. Enjoy!
