Apple watch automatically sent a text "Check out this watch face"

I found that my Apple Watch had sent a text to one of my recent text messages. I never sent this myself. It wrote "Check out this watch face" and then below that was a picture of a watch face with a text below it saying "Add Watch Face" and "Apple Watch". Clearly this was some automatic send from Apple and I wonder if this is some new ad campaign that is hijacking my text messages. It very strange. I had to reply my contact that the watch must have automatically sent this maybe as an advertisement.

I did see a couple of other posts in this Community about the Apple Watch sending random text messages. I couldn't reply to those so I started this new post.
