Here is a picture from Christies:

I reworked the picture to get this close up.

The 5970 is for me one of the best perpetual calendar ever made by Patek. Even nicer for me than the elusive and legendary 5004 ( adding a Rattrapante ), if we consider the proportions.
Now, if I had to choose, I would love to get the salmon dial, or this black beauty ( 5970P ).
The case and the dial, without forgetting the Lemania movement, are more my taste than the current one.
Best,
Nicolas
