TIA sa mag input
As always, least aggressive option first. If a wash does not remove them, you can try, in succession:

1. non-abrasive chemical cleaner (Klasse All In One, Meguiar's Deep Crystal Paint Cleaner)
2. mildly abrasive cleaner or polish (Mother's Pre-Wax cleaner, Meguiar's Ultimate Polish)
3. medium abrasive polish (Meguiar's Swirl-X, Meguiar's Scratch X 2.0)
4. aggresive compound (Meguiar's Ultimate Compound)

Please don't use anything more aggressive than Megs UC (even that is a very aggressive product already) - you risk thinning your clear coat unnecessarily (and possibly dangerously) with old-school rubbing compounds. After you get the watermarks out, do protect your paint with a wax or sealant.
