Cookoo: Long Battery Life
Most smartwatches require recharging via USB cables. But the iOS-compatible Cookoo uses a standard CR2032 battery supposedly good for 274 days.
Cookoo departs from the crowd in other ways, too. It has a standard watch face instead of a screen. Icons on the watch face light up to alert you of incoming calls, calendar reminders and such. And it can trigger your smartphone’s camera. The New York Times' David Pogue says the Cookoo's $130 price is "reasonable. But there are lots of rough edges and missing features."
Status: Available now.
