Just the thing for that last-minute Christmas present for the man who has everything – an almost useless wristwatch telephone developed by AT&T Co’s Bell Laboratories in Murray Hill, New Jersey; an inner strap holds the device on the wrist and an outer strap contains the receiver and speaker, which pop up and spin around, ready for use, when activated – When the phone rings, you press on the speaker, the outer band pops out, the strap straightens and rotates around you, put your hand up to your ear and you’ve got the speaker in the cup of your hand and the microphone at your wrist, the New York Times reports: : the battery and antenna are so tiny that the range is only about 100 yards, but that may be fine for showing off by calling up your caddie on the golf course.
