German firm Armatix shows at the Shooting Hunting and Outdoor Trade (SHOT) Show its Pistol/Wristwatch combo. The idea is that the pistol will be automatically disabled when it is not within a few inches of the custom wristwatch.
The watch sends a wireless arming signal to the gun. If the gun is picking up a signal from the watch, a green LED on the back lights up. Try squeezing the handle without wearing the watch, and you will see a red warning light.
The limited edition of pistol is priced at Euro 7000.
