Congrats on your nice pickup.
Gen bracelets are not all that much. For the 9315 some guys buy the watchinternational folded bracelet from Mary, and add a gen clasp and endlinks, pretty good quality.
If you add a gen bezel, make sure you buy the set... including the retaining ring, not just the bezel...or you probably will have problems fitting it.
I meant to tell you ebay seller "Swisstickers" usually has brand new genuine eta 2846's for 99$ shipped..several of us have bought from him.
The parts hunt begins! Good luck!
