Smartwatches can leverage the power of your phone to do a great many things. For example, one can use GPS to calculate your speed. It’s a feature pretty much relegated to the digital world. But if you’re looking for a more elegant timepiece, and you happen to have the need for speed, perhaps you should take a look at the Genie 03 from Breva. The world’s first-ever wristwatch with a functional speedometer uses wind to help measure speed. The tiny speedometer pops up when in use, and can track speeds up to 200 km per hour. There are issues, as you probably guessed from how it works. You need to be on a bike, boat, or somewhere not shielded from the elements, and you have to be willing to adopt a bit of the metric system. Oh, and then there’s the price tag. Still, it’s pretty stunning and smart.
