I’d choose the Nomos Club Campus 36. Here are my reasons:
- 10 ATM (water resistance is important to me)
- 36 is a more classic size
- the lugs are nicer than the Ludwig but the dial is simpler than the Longines.
- nicer colours (you could get white for a more dressy feel but have the orange accents for the flair)
- California dial is so nice.
