It's the best chronograph, from this era, Rich said, adding that, with the $15,000 I've allotted here, I can wait around for a particularly sharp or unpolished example with original lume intact.

He also mentioned that I didn't yet have a black dial in my collection, so the 2447N fills another best men's sport watch gap, one I didn't even realize I had! Cost: $15,000. Remaining: $10,000
