The Fossil Caller ID watch with Bluetooth technology keeps you connected in style by combining a vintage analog/digital watch design with Bluetooth Wireless technology. Silver with black rubber strap design.
It notifies you when your phone rings with a discreet vibrating sensation and showing the caller's name and/or number on the bright OLED display. When an SMS/text message is received the watch will vibrate and the text alert icon will appear. You can mute the phone's ringer or reject a call by simply pushing a button on the watch. Works in conjunction with a bluetooth headset, see who is calling on your phone and answer on your bluetooth headset.
Fossil partnered with Sony Ericsson, a world leader in mobile phones and a world leader in Bluetooth technology, on the creation of the Bluetooth watch. Fossil provided the watch design expertise & manufacturing capabilities, while Sony Ericsson provided the Bluetooth software development & phone integration expertise. The watch is compatible with most Sony Ericsson Bluetooth phones as well as Symbian smartphones such as the Nokia N series.
