It's a nickel plated 2486 iirc, the slowbeat one. I've never seen rep 'swiss' nickel plated movements. I don't know much about the datewheel, apart from the 3s and 6s are correct; if that's something PT did then it may very well be the PT datewheel, as I think the case came from him.
The Members from whom the watch came from are fairly highly regarded, so it's unlikely it (the crown) was mis-sold to me. Also, the coronet is perfect, and the crown/tube gasket system is exactly like the gen, and it opens and closes perfectly. Thanks for your concern though .
There is texture to the lume, but it's not too much. When I fish out the proper camera I can take some macro shots, and shots of the clasp and endlinks of course (they are rep btw).
EDIT: here's some pictures that you requested, including one for myself http://imgur.com/a/CCgLp
