Imagine getting a call and whipping one of these super high-tech cellular bracelets right off your wrist to pick it up? Dubbed “the Dial” by its inventor Jung Dae Hoon, this wearable technology is not exactly the greenest gadget, but we think the fact that it serves double duty as an accessory and has a small material footprint is worth mentioning. We also like that it offers the option of several interchangeable skins, so that you can just give your Dial a facelift if you get bored with it instead of buying a whole new phone.
