Abstract: A skeleton watch includes a case middle which defines an interior space, a crystal and a back cover fixed to the case middle on either side of the middle to enclose the interior space, and a movement. The movement includes an openworked frame having a front face and a back face, the frame including an outer perimeter formed by two side positions, a top bar that connects between upper ends of the side posts, and a lower platform connected to lower ends of the side posts. The frame includes a central island positioned within the outer perimeter. The movement also includes a minute hand and an hour hand mounted on a central arbor integral with the frame. The movement also includes a motor having an electromagnet that extends outside of the outer perimeter of the frame in a radial direction from the central arbor.
