New old stock, fully stickered "mark I" Rolex 116520 steel Daytona, now discontinued, its time to start dissecting this reference properly... This example with its distinctive "thin hands'' and "5 tick" dial is the 1st generation of Rolex's in-house Cosmograph, will it go on the be the next "porcellano"? Probably not, but history teaches us to never underestimate the 1st series of any major Rolex model..
