Motorola is all set to unveil its Moto 360 watch at a press event in Chicago on September 4th, but it looks like Best Buy has let the cat out of the bag. A product page for the Android Wear smartwatch has mistakenly gone live on Best Buys mobile site, and it lists the device with a $249.99 price tag. The fine print of the official rules for a Motorola contest this past May placed the smartwatchs approximate retail value at the same price. Droid Life first reported on the leak earlier this afternoon. The Best Buy page does list some preliminary specifications: the LCD touchscreen is said to come in at a resolution of 320 x 290, and the display is protected with Gorilla Glass 3.
