The LaserWatch has an LED watch module, a metal body, a clear carbon coated cover, and a 1,500-milliwatt laser. You will be able to shoot the laser for 5 to 10 minutes before there is a need to recharge the large lithium-polymer battery that has been built into the strap. In the video below, Priebe can be seen using the laser to pop balloons, light matchsticks, burn a hole on a plastic CD case, and cut a duct tape. That means the laser is powerful enough to harm people. Priebe is saying that it is hard work to build the laser watch. So if ever he's selling his new product, the device will have a price tag of at least $300. But we are not sure whether or not the device is legal.
