I accidentally hit the water drop on my Apple Watch series 2.

Follow this guide:

How to use Water Lock and eject water from your Apple Watch - Apple Support

How to turn off Water Lock and eject water

Turn the Digital Crown on the side of your Apple Watch until the display says Unlocked. You can rotate the Digital Crown in either direction.

Good luck!

Go into the watch app on the phone and tap on accessibility and turn on zoom.

Try it first.
