Sony smartwatch 3 mute??

So. I might be being very very stupid here. But when I'm at home chilling with my phone in hand. I see no reason for my watch to also vibrate. I Googled how to stop this and saw there is meant to be a mute button when I scroll down from the top. I've seen it on videos and pictures. But when I do all I get is battery percentage and the option to activate do not disturb. But this also activates it on my phone?

I'm aware I can turn off notifications for apps altogether but I don't want to do...
