Smart watches have typically been the domain of geeky-looking wrist adornments that make their intelligence readily known. Until now. The Casio G-Shock Bluetooth Watch ($180) hooks up with your iPhone using Bluetooth 4.0 while retaining the classic G-Shock profile. Thanks to the connection, you'll get incoming call and email alerts right on your wrist, as well as automatic time setting, an alarm when your phone drifts too far from your watch, and even a feature that can sound an alert when it's time to find your trusty pocket computer. Available in four fashionable colorways.
