Broken crown button (doesn’t rotate) - how do I turn off water mode?

I have the water mode on my watch turned on accidentally and now I can’t turn it off. The crown button still rotates, but it doesn’t do anything for my watch. This means I can’t adjust volume (annoying but fine) but also I can’t turn off water mode. Tips?

I tried restarting my watch, which worked but didn’t turn off water mode. I can’t activate Siri with water mode. Pressing either button does nothing except pull up a screen that tells you to turn off water mode. Touching the screen doesn’t work because, again, it’s on water mode.
