Question about value of Vintage PN Daytonas

[guffyboy92]

Hi TRF,

I've been into watches for some time, but I'm not particularly versed in vintage Rolex knowledge and was just curious about Paul New Daytona's. Succinctly, what exactly made the PN's arguably the most valuable watches in the world, commanding astronomical prices? Was there a particular event that sparked the fire? Was Paul Newman really that substantial of figure in Rolex culture? Were they made in very small quantities?

Thanks and hoping to gain some to new knowledge!
