This is my favorite of the current Patek line and the one I'd most like to own. Short of something crazy like a 5275P or a 5016 of any stripe, the 5236 embodies so much of what I love about the company. I'm not surprised by the dragging calendar turnover, because instantaneous perpetual calendars are rare and shockingly expensive even by PP standards. This is a super cool watch that looks as special as it is, and I can't think of a neater way to get into Patek today. From what I understand, this isn't an allocated model (for dealers) or an application piece (for clients), and thank God for both. There's enough of that already.
