As you probably know, quite a few Watch OS features are toggled through your iPhone's "Watch" app, while having your Watch close to your iPhone. i.e. Enable/Disable microphone access on your Watch via your iPhone's privacy settings.
Having said that, try playing around in the Watch app on your iPhone, and also see if you gain any additional settings from VO while your Watch is close by your iPhone.
