Thank you all for your tipps, I bought the book some minutes ago here you can find it .-)
I am not happy with the dial on my watch because of the closed "6" and "9" and the structure of the sub-dial background ...
the ROLEX-sign (crown), "OYSTER" style and "COSMOGRAPH" letters are ok and nearly authentic.
The hands of the sub-dials are wrong too, black, not white; but I found betters ones at Clark, USA, No 400 to fit 727 movements.
I have decided to fit the watch with this dial (thx again for the info, Freddy), the ROLEX-symbol will be eychanged with the one on my old dial, because I think it is better.
A gen dial for comparsion (NON-OYSTER, but the same) comes here ...
When I will have finished my little project, I will show some more pictures.
Thx for discussing and looking
