Which message app are you using?
Did you already try to force restart your iPhone and Apple Watch?
Force restart iPhone - Apple Support
To force restart your watch, press and hold the Digital Crown and the Side button together for about 10sec, until the Apple logo comes back again.
In the Watch App/Messages on your iPhone, "Mirror my iPhone" is enabled?
