Hi Dje,
some time ago, I was about to get a plain Calatrava with the caliber 215 PS.
As much as I liked the classical case and dial (and the marvellous video "To my Son"), I could not convince myself to buy a watch, which is not really cheap, and does not even have the stop second function to set time accurately.
I asked my AD whether he might inquire the Patek people about this, but he said, there was no chance they would listen to him!
Probably they will listen to you?
Thanks for considering this question.
Kind regards,
anaesdoc
P.S. BTW - I ended up with a VC Patrimony Traditionelle...
