Hi Arthur,
Thank you very much for this historical review.
These perpetual calendar chronographs are obviously more than appealing and there is no doubt to me that all the interest we see here and at some other places about the 5970 for instance is teh result of passion and not just speculation. Yes these watches have no real competition IMVHO they compete between themselves for our hearts!
If the 5970 is not there anymore in Basel I'm sure we'll see the new chapter! With such a short life and a success a new chapter would justify only with a new calibre. Quite promising no?
Thanks again
Dje
