What is the most expensive everyday dress watch you own?

[amphr1]

Taking inspiration from another thread. Recently I've been having this itch for a croc leather white face dress watch. Today i was watching the Netflix show Lincoln Lawyer and saw the prosecutor wearing a Daytona. I suppose you can count it as a dress watch, because it's somewhat simple, and very expensive.

Anyway interested to know what you folks own. For now the only dress watch that I could wear daily is from a micro brand call DuFrane on brown leather strap. But maybe the Rolex president or Daytona will be in the future some day.
