The World's First Wrist Watch With Built-in GPS

First ever wristwatch with built-in GPS

Casio had announced the world's first wristwatch with a build-in GPS in Las Vegas. The Casio Global Positioning System watch picked up transmissions from 27 GPS satellites developed by the United States. The actual product was released in June 1999 under the nickname Satellite Navi and was the top model of Casio's outdoor watch series, Protrek.

Smartwatches have been promising to be the next big thing in tech for a few years now, and while we wait for that to happen, let's take a look back at 1999 when Casio announced the world's first wristwatch with a built-in Global Positioning System (GPS) at CES Las Vegas.

The screen displayed a crude map of the position of the watch and had 10 hours of battery life during continuous use.
