Although I now only buy watches with the intent of owning them forever, this one's certainly at the top of the list of watches I'd never sell.
It's the one that restarted my interest in watches after having sold all but one Rolex and a few low-end vintage pieces from when I collected back in the '80s.
When I found this Millenary I was surprised to discover how much current watches had changed over the decades since selling off my original collection. Of course since then the collection has grown again, but now, with rare exceptions, I only buy watches that I believe I won't ever tire of.
