New and on the road to understanding

Hi, I'm new to this fascinating hobby but a veteran of having mechanical movements.

It all started about 42 years ago when I bought my first (an Omega Seamaster Professional AKA Bond watch, hate the moniker, but that's OK) although my non-understanding beginnings started much earlier in the sixties when my grandfather bought me a Festina.

I have bought some movements- mostly copies of 2484 (Seagull) and have a couple of NH35A-based watches that I've got on a Weishi timegrapher and currently regulating as they're relatively new and don't need servicing just yet as the amplitude looks good on them.

I wanted to do that before dismantling anything so that I learn an understanding of the power train/winding mechanisms and regulation.

This, primarily because if I dismantle a movement and put it back together  and it doesn't work, or has a worse amplitude, then I know I may have done something wrong.

As a gas engineer, I liken it to the method we've got ingrained- check gas isn't leaking BEFORE doing any changes to the pipework, then test again after to check if there was one, it wasn't mine....

Anyway that's me. I'm sure you're a friendly bunch...
