My thinking:
Yes for the nautilus, possibly yes for the pilot (even though somehow the color combination works less well for me) and rather not for the calatrava and worldtime chrono.
And to precise my thoughts, it just a guts reaction based on looks and colors, not undue restriction/fear in terms of dress watch.
For instance I believe the last two (calatrava and WT C) would both fit very well with a saffiano leather or possibly even sailcloth if the finish is more clean and that would dress these down seriously .. while retaining more the look.
Hope it makes sense?
And of course, as they say in French “gouts et couleurs…”
