This is the watch that has a built-in touchscreen cell phone. The phone's 1 1/4" touchscreen detects the slightest touch of the included stylus for easy dialing. It comes with a Bluetooth headset so you can easily carry on conversations "wrist-free." It operates on the same tri-band network as other cell phones--GSM900, 1,800 and 1,900 MHz--enabling you to place and receive calls in most of the world's countries. It has a built-in 1.3 MP camera that stores its videos and pictures on the included 1GB microSD card. You can also download MP3s onto the card and play them using the phone's integrated MP3 player. Four 1/4" speakers located at each corner of the face provide clear sound for music and the speakerphone. Its rechargeable battery requires a 1 1/2-hour charge using the included AC adapter; provides up to three hours of talk time (3 1/4 hours for stand-by time). Requires existing cell phone service and SIM card; will not operate with Sprint or MetroPCS. Face 1 3/4" H x 1 1/2" W x 3/4" D. (12 oz.)
