Well, I was lucky enought to find some good deals, and the weak dollar helped me a lot. (I'm in EU)
Stephane you're right about the second hand sub, maybe when I'll get bored one day, I'll re-sell the genuine parts for buying a gen. Not a big deal..
As rosnik said, this is more or less how much I paid..
Bezel and insert: 250$, I like it a lot, you can just replace the insert and have a pretty good bezel.
Crystal: 120$, a must, WM9 etched crown was terrible like the SSD's
Crown: 90$, not necessary as WM9's has the same genuine specs. As suggested by Tribal I kept the rep tube.
Noob dial: can't remember, but I'd say around 30$
Bracelet: 500$. It was a real bargain converted in EU.. You can use a rep bracelet + WM9 clasp and it looks great anyway.
More ore less 1500$, and 3 months spent on my hobby
Thanks you for the comments!
