Smartwatches are notoriously codependent gadgets. If you want to use one to make calls, you need an auxiliary device nearby to do the cellular legwork. Forget smart, they’re like mini-dumb terminals, wrist-bound proxies for another functionally better-rounded piece of technology. Until now: Meet the Gear S, a curved-screen smartwatch that maker Samsung says can do phone calls all by its lonesome. The Gear S uses a curved 2-inch 360-by-480 pixel Super AMOLED display attached to a flex band (with changeable straps), and employs a customizable interface that includes views and fonts Samsung says will let you “read messages and notifications at a single glance.” The IP67-certified (particle and moisture resistant) wearable is powered by a 1.0 Ghz dual-core processor, has 512MB of memory and 4GB of internal storage, and runs Tizen, the Linux-based operating system for embedded devices.
