ABSTRACT:
A portable radio telephone device which is in the form of a wristwatch which is fastened to the user's wrist via a strap. The telephone device is comprised of two main components, a case and a strap. The case has a display and a transceiver. The strap or band has at least a top and a bottom layer which are attached to the case. The top layer of the band is releasable in the proximity where the case and strap meet. However, the top layer remains connected to the bottom layer of the strap by a pivotable hinge. The pivotable hinge is typically located opposite the case and permits the top layer to be rotated. The length of the top layer can be increased either by repositioning the case or having additional layers located beneath the top layer. The speaker is located on the end of the released top layer. The microphone is located on the band. When the top layer is released and rotated, the speaker is located in the palm of the user's hand and the microphone is positioned along the inside of the user's forearm. This design provides for a private telephone conversation without the removal of the telephone device from the user's wrist.
