Realistically, right this second- I don't even know where to get the $25 replacement asian movement your talking about, who makes it, what model to request, or how to install it. Now figure, as into reps as I am, as much as I read these boards, the amount of knowledge to keep up with is still infinate. Look how much I don't know. Genuine ETA's take a lot of the guesswork out for someone like me, and at least they used to be, worth the additional premium to have the ability to take it to joe blow watchsmith and say "here, fix it". God bless The Zigmeister ten times over, but we can't rely solely on him forever. He could decide to drop everything, and become an astronaut tomorrow (or a home renovator?! ) and theres not a d@mn thing anyone of us can do about it.
I still have a lot to learn. You basically have to be a novice watchsmith to run in this circle, or at least run in the right direction.
