Genghis of France has come up with the Hidden Time Watch concept which was specially designed to help you tell the time discreet. We think it can be potentially distracting in a closed room meeting as you will need to peel open the strap a bit to check out just what the current time is, instead of looking at your watch with a discreet glance. While the display itself relies on LED technology to tell the time, don’t fret about battery life since the LED will spring into action only when the strap is peeled off.
