Good with tux?

Apologies if this is in the wrong forum. Mods, please move if necessary.

I currently own a SS DJ2 (first "nice watch" I have bought, love it dearly), and am thinking about buying a watch for formal (black-tie) events. I know some people are okay with wearing a non-Cellini Rolex to black-tie, or even (gasp) white-tie functions. However, for me, a classic dress watch has always had the following characteristics: simple, thin, leather strap, and preferably precious metal.

My dream dress watch would be a PP Caltrava, Jules Audemars, Breuget, Piaget, etc. However, those are slightly out of my price range. Therefore, I am considering the following:

or

I am leaning towards the non-blue hand model, because I feel like the blue hand does not quite go as well with a tux. Would really like the forum's opinion, as well as their opinion on Nomos as a brand in general, and whether you guys consider the models above to be a "classic" dress watch. Thanks in advance.
