As shown in the earlier leaks, it has a 1.4-inch flexible OLED display on the band, but what hasn't been obvious until now is that it also supports wireless calling -- there's a removable earpiece tucked inside it, which explains the 14.6mm-thick bulk. Like any good
wearable, the device also has fitness tracking features: It records how many steps you've taken, how far you've travelled and how many calories you've burned. It's also a sleeping pattern monitor, so you can use the smart alarm function to wake up at the optimal time. There's NFC here for pairing with phones, and the 90mAh battery promises six days worth of usage (but takes two hours to charge up).
