Apple Watch Texting Without iPhone

So I left my iPhone at home today, but still seem to be able to get and receive text messages in my office. I assume it's paired to my Mac at work somehow, but I'm a bit at a loss for how that happened as I never paired it manually, and there isn't any way to connect it to my office WiFi.

Anybody know exactly how this works?

The Watch can autonomously connect to wifi hotspots your phone has used previously and do things like iMessage...
