First watch that comes to mind - Nicolas's 7924 BC. But he knows that already!
Additionally, Bill's 5510 BC. And yes, he knows that already, too!
Other than that, there are some very rare and very nice watches on this site, but none of them are ones that I "covet".
Actually, one more - Dr. Strong (Jeff's) 5513 Tiffany Dial. What a rare watch and such a beauty!
Any one of those three watches on my wrist and my collection would be absolutely complete. A 16600 Sea-Dweller and one of those three watches - what else does a man need?
