Abstract
A wristwatch radiotelephone is usable as a radiotelephone without the need to remove the apparatus from the user's wrist and without the need to plug any additional elements into the apparatus. During radiotelephone use, simultaneous placement of microphone and speaker ports adjacent the user's mouth and ear, respectively, is facilitated by having at least one of these ports deploy from the remainder of the apparatus to increase the distance between the two ports.
