Abstract
A combined wristwatch and radiotelephone has a portion such as a wristband which typically remains on the user's wrist, and a timekeeping and radiotelephone portion which is typically removable from the portion that remains on the wrist. The wristwatch and radiotelephone portion is reconfigurable between a relatively compact form in which it is suitable for wearing on the wrist as a wristwatch, and a more elongated form in which it is suitable for use as a hand-held radiotelephone with a microphone and speaker spaced sufficiently far apart to permit simultaneous use of those components adjacent the user's mouth and ear.
