WAAAAAYYYY too many taps and defeats the whole purpose of the watch.
Instead, rotate the Apple Watch up to activate it and use Siri and say:
"Hey Siri. Send a text message to John Doe that says see how easy this is exclamation point you don't even have to touch the Apple Watch period cool comma huh question mark."
Siri will launch the Message app, create a text to John Doe that reads "See how easy this is! You don't even have to touch the Apple Watch. Cool, huh?" The message will stay on the screen for about 30 seconds with the option to cancel. After that time, if you haven't canceled, the text message is sent.
THAT'S the power of the Apple Watch!
