I'll just post the contents here. The auctions that I linked to are all ended, so you'll need to use these as references on what to get:
Start with this case set:
Case Set.
Use the movement from this watch:
Valjoux 72.
Use a dial like this:
Dial.
The dial is, of course a redial, as a genuine dial is going to cost a fortune. On the rare and sought after models like the 6239/6240/6241/6262/6263/6265 (standard and exotic's) the dial is 80% of the watch's value. So, the only economical way to do this is with a non-genuine dial.
Once finished, you will have a very nice 6263!
I hope this helps...
Best regards,
