Which watch should I take to an event

I'm going to a cars and watches event. Been trying to decide which watch to wear and have narrowed it down to my Breguet Tradition and Lange 1815 Up/Down. The Lange is more understated, the Breguet a bit more of a conversation starter perhaps, but either is likely of interest to a watch nerd. Which would you take? Which would interest you more if you encountered it?
