Maybe you missed out on Jimi Hendrix’s “Woodstock” Stratocaster, which sold for a reported $1.3 million in 1993. Perhaps you were too slow to raise the paddle for the prototype Apple 1 computer, thought to be Steve Jobs’s and Steve Wozniak’s first, that fetched $815,000 last year.

Luckily, you still have a crack at Paul Newman’s Rolex Daytona. This opportunity may not seem significant to the cellphone-toting masses who think of mechanical wristwatches as anachronistic devices once used by their grandparents to tell time. But to the swelling legions of watch geeks worldwide who think of vintage timepieces as fine art, a so-called Paul Newman Daytona is the one watch that seemingly every self-respecting collector needs to own.

And Paul Newman’s “Paul Newman”? It is basically the Mona Lisa, perhaps the most famous timepiece in the world, coveted all the more because for decades, no one outside the Newman family seemed to know where it was.

Well, the secret is out. On Oct. 26, Newman’s lost masterpiece will go on sale as the centerpiece of a watch auction at Phillips in New York, following a treasures-of-King Tut-style world tour to whip up interest — as if interest actually needed whipping up.
