Face to face, or after this amount of time a face to fist, or a forehead to face, or mayby if you took him a nice bottle of wine like what people do to the rolex AD when they want to get on the waiting list for a daytona.
My best suggestion would be to get a copy of Henry B fried's book, "The watch repairers manual", part 7 pages 97 to 128, in there it lists every thing you would need to know, but you would need some specialists tools like a lathe and staking kits. The book is worth every penny, If i was going to be around next week i would copy it and post it over but i will be away from the office unfortunatly
I would say that the small finishing touches would be the hard work, i am sure that a good CNC mill could cut the 3D case spot on but you try to finish it to the same standard by hand with out the experience of doing it day in day out!
