I have no problem with the Cal 240 as a base for a QP.
I agree that it is a fine offer from Patek.
BUT I can't have two Patek watches sharing the same calibre, the noly difference being the module. ( WT, and QP ).
I already have the WT, so I can't, due to my platinum rule, go for the QP.
And even less for the Celestial, for the same reason, to be clear.
Best,
Nicolas
