I just picked up this watch from a seller in the UK (been trying to get one for quite a while) and have a couple of questions:

1. I'm guessing the back is not the original one for this model, correct?
2. Can this watch be wound by the crown? It doesn't feel/sound like it's winding when it's pushed in all the way--and it's hard to grab ahold of the crown like that.
3. Is there a manual for this model posted online somewhere?
