Here's The 1994 AT&T Cell Phone Wristwatch That Never Happened
This idea, they promised, "will happen."
AT&T's "You Will" promised a high-tech future...
In the '90s, AT&T ran a campaign imagining the future of technology, and some of it was stunningly accurate ā iPad-like devices, Skype-ish capabilities, personal GPS devices. One of the ideas, they said, would come would be a "strap-on telephone."
Here's an ad AT&T ran for the non-existent gadget, stating that AT&T would be "the company that will bring it to you."

We haven't quite caught on yet...

Looks like this was one AT&T idea that wouldn't really be a part of our future. At least, not yet. There have been rumors and speculation that Apple is producing an iWatch (which folks think would be more of a wearable computer-y thing). Or perhaps you heard the buzz about a Kickstarter campaign for something called the Pebble, a wrist device that syncs up with your phone's apps/delivers notifications, but doesn't do calls. More recently, there's a Kickstarter for something called the HOT Watch, which would actually let you take calls just by holding your hand to your ear.
You broke your promise, AT&T!
