A device for determining a position of a horological display, the device including a control device coordinating a time base, a shape recognition device, and an optical acquisition device. The control device identifies the display and monitors its travel in order to code its instantaneous position in relation to a fixed guide-mark, and controls entries of its position at distinct instants in time to determine its mobility in relation to the fixed guide-mark. The device includes a device for determining the depth position of the display in relation to the fixed guide-mark, a device for controlling the position of the optical acquisition device, a device for controlling a focus of the optical acquisition device, and an additional optical acquisition device coupled with the optical acquisition device to interferentially monitor the display.

Device for determining the position of a horological display

A device is disclosed for verifying the state of a watch and resetting it to the correct time. In a case of the device, a watch can be disposed on a watch support, which can be moved from a position without measurement to a measurement position in a vision system, or vice versa. In a position without measurement, the watch on its support can be observed from the outside of the case of the device through at least one electronic shutter activated or an optical valve activated to be in a transparent state, whereas in the measurement position, the electronic shutter or the optical valve is deactivated to be made opaque.
