Abstract: A system and method to determine an angular movement of an arbor integral with a crown of a watch, the arbor being rotatable in a longitudinal direction. Included is a rotating reflector mounted on the arbor, and two emitter/detector pairs disposed on either side of the reflector. Each emitter/detector pair includes a light source for illuminating the reflector, and a light detector for receiving the light reflected on the reflector and for generating an electrical signal representative of the reflected light. A processor processes the electrical signals and determine a parameter relating to the angular movement of the arbor. The rotating reflector's visible outer surface changes when the reflector rotates on itself in a regular manner, such that the representative electrical signal generated by said detector of the pair has a substantially sinusoidal shape when the reflector rotates on itself in a regular manner in a same direction of rotation.

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.

Abstract: A system and method to determine angular movement of an arbor integral with a crown of a watch, the arbor being rotatable on itself in a longitudinal direction. The system includes a rotating reflector mounted on the arbor, and two emitter/detector pairs disposed on either side of the reflector, each including a light source for illuminating the reflector, and a light detector for receiving the light reflected on the reflector and for generating an electrical signal representative of the reflected light. A processor processes the electrical signals, and determines a parameter relating to the angular movement of the arbor. The rotating reflector is a cylinder of revolution and light absorption points are made on the circumference of an external cylindrical surface. When the reflector rotates in a regular manner and in the same direction of rotation, the representative electrical signal generated by each detector has a sinusoidal shape.
