Regardless of ones opinion on Patek, few can admit to not admiring the 2499. It is an incredible feast for the eyes to anyone who enjoys watches.
Now for prices I am in the camp of thinking they are far from crazy. Compare to what exceptional cars and art watches are still a poor mans hobby. In my opinion of course. An exceptional 2499 is a piece of horological history at its finest. There are crazier things to purchase even in this price range...
