The idea has been with us for more than half a century, but the successful execution of a practical, effective - even stylish - wristwatch phone is only just starting to become a reality. Two examples showing innovation in both technology and design emerged at CeBIT 2003 - NTT DoCoMo's Wristomo and Samsung's GPRS Class 10 watch phone.
Built by Seiko, Wristomo's unique design enables it to be taken off the wrist and used as a handset. The phone supports web browsing at up to 64kbps, emails to a maximum size of 3,000 characters, promising continuous talk-time of two hours.
Billed as the world's smallest GPRS phone, Samsung's new Class 10 watch phone offers one and a half hours of continuous talk time supports voice activated dialling, WAP 1.2, Bluetooth and Speakerphone technologies.
The phone weighs only 80 grams including battery and measures just 37.8 x 64 x 17.7 mm.
The watch phone display is a 256 OLED (Organic Light Emitting Display) colour screen that features 96 x 64 pixel resolution.
