A timepiece movement includes an analogue display, including a rotary indicator and a wheel that rotates as one with the rotary indicator. The wheel includes a plate with a locating element. The timepiece movement also includes a device for detecting at least one angular position of the locating element, which includes a board that is fixed with respect to the plate, extending substantially parallel to the plate, and on which a first electrode, a second electrode, and a common electrode are arranged. The electrodes are planar and are arranged such that, in one angular position of the wheel, the locating element is located over at least a portion of each electrode.
