The Timex Data Link is one of the earliest examples of smart watches, dating back to 1994. Timex and Microsoft worked together to launch a watch that translated the data from bar codes displayed on Windows computer screens to the watch's memory. It was wireless, but without radio signals. The version seen here, the Datalink USB Dress edition, dates back to 2003. Those squares on the screen? No, they're not artifacts from a damaged LCD screen. They're part of a game called Invasion. Be thankful that computer graphics have improved since then.
