My fondness for Patek has little to do with their complications, in fact I know very little about Patek movements, I know much more about Asian movements than Patek... My fondness has more to do with how Patek markets itself and the aesthetics of the watches they produce. More than any other brand they release timepieces that i perceive, subjectively of course, to be synonymous with class and elegance. This is not of course limited to a single reason, their rarity, understated elegance, and reluctance to use "celebrities" to sell their watches resonates with me. I am no doubt impressed by several other manufacturers who release celebrity associated watches, Richard Mille's Rafal Nadal RM005 is very pretty, but I've no desire to own it or wear it. The new large RG AP's that keep being released are nice in a magazine but again do not elevates ones soul to the point of spending tens of thousands of dollars. I actally prefer the SS 15400 to any of their more expensive line.
I gather from this thread that HW watches clearly resonate with you, and good for you for having a passion for them, but in my list of favourite watches Patek have at least 4 in my top 10, just personal preference.
