I know, I know: A Bluetooth watch? Is this another in the long line of failed "smart watch" experiments that implored gullible gadget lovers to attempt to read emails on a half-inch monochrome screen? Thankfully, not at all: Casio's new Bluetooth watch concept
syncs with a smartphone in ways that make sense and don't overreach. It uses an ultra-low-power version of Bluetooth (a gadget using this new type of Bluetooth can last for a year on a normal watch battery) to sync with an Android smartphone, mostly for notifications. Got a new phone call, email, or text message? You'll get a little beep and the name of the sender or caller on your wrist, even if the phone is in your bag or deep in a pocket on silent mode. It also has a "track my phone" feature that'll stop the undignified practice of asking for a friend's phone to call your own, only to find it somehow sitting next to the toilet.
The Bluetooth watch is a "concept" because it hasn't been officially announced in a product yet--but in our hands-on experience
, it's perfectly functional and ready for release. You might see this in a G-Shock watch later this year.
