Being a big 1921 fan (...and not owning one) the man's choice is just right. All I have to say about your wife's watch is....she's one fortunate lady!! (My wife better not see this page!) Great combo. For less formal, I like Alex's choice.

Les Univers Infinis - Horseman

Last, but not least...Welcome to THL!
