Hello! My name is Dan, and I've just recently started trying to figure this stuff out....I'll never know as much as I'd like, I'm sure..
At any rate...my grandfather died 45 years ago and left an old Paul Breguette mechanism (no case or band) ....tried winding it..and it started running
but it definitely needs work. I don't have the money necessary to pay a master watch maker to repair, case and band it, so I thought "eh, why not?"
and bought some tools...(Timegrapher, An Amscope binocular microscope and some tools...)...I suspect I'll destroy a number of mechanisms
before I actually get one to work again ...any tips or stories are greatly appreciated!
