  • Patent number: 5572488
    Abstract: A paging receiver as part of a wristwatch. Received messages are displayed using an analog mechanism. A plurality of disks largely hidden behind a watch face, but having a small area visible through an aperture in the watch face, can be independently rotated to display standard messages, coded messages, and number sequences. Other analog watch mechanisms such as drums and sliding bars visible through respective apertures in the watch face can include marks representing standard paging messages. These other analog watch mechanisms can be moved such that a selected mark is visible through the respective aperture in response to receiving a paging message. A special hand on the watch may be controlled to point to markings on the watch's face or bezel which signify standard paging messages received by the pager.

  • Patent number: 5479378
    Abstract: A paging receiver as part of an analog wristwatch. A received paging message is displayed using an analog watch mechanism which includes hands that are independently controllable. Around the perimeter of the watch face or on the watch bezel are marks representing paging messages, such as "Call Home,", "Call Office", etc. Paging messages are displayed by using one of the hands which normally is used to indicate time to point to one of the marks or messages on the perimeter of the watch. Optional features include using the watch hands not used to point to a mark representing a received paging message to point to a predetermined location to alert the user that a message has been received and using an LED can be used to indicate that a message has been received or that a message is pending. Other analog mechanisms, such as disks, drums, and sliding bars visible through respective apertures in the watch face can be used to display information concerning paging messages.

  • Patent number: 4862434
    Abstract: An electronic timepiece in which a gear train is driven and the hand is moved by a stepping motor and, more particularly, the timepiece which surely permits time correcting owing to the simple structure even if the gear train is formed of plastic materials. One end of the third wheel and pinion engaged with the center wheel is guided or held by the operating lever interlocked with the external control member. When the external operating member is moved into the axis direction, this operating lever is rotated and the third wheel and pinion is radially removed from the engagement of the center wheel and pinion.
