  • Patent number: 4660992
    Abstract: A watch body is formed with a platform from which extends a stop and a stem, which stem includes watch hands. A rim extends along the periphery of the watch body and a transparent covering is secured to the rim and extends above the platform. A watch face is received on the platform and includes a slot through which the stem extends. The slot also cooperates with the stop to prevent movement of the watch face on the platform. At least the rim of the watch is formed with a portion which may be removed and replaced to permit insertion and removal of the watch face on the platform.
