5970 (yawn yawn) , 5101P, 5078P, 5016 are among the grails.
But what I really hope for is a time only grail from Patek.
There isn't anything outstanding from the current collection.....Calatrava 5916P is almost there but
the small movement ending up with a too high second hand dial, is a big compromise to make it a cult /grail.
5970 seems to be the only one that kinda represent the most usable grail currently.
It has the seemingly perfect case size and wonderful classic dial. Looks great in any metal too.
Though I must say the mentioning of this reference give me cringe lately, it is still a very, if not the most beautiful piece in modern Patek.
Cheers,
