A trigonometric function display clock includes a clock face that has a center aligned with a central axis, axial markings aligned with an x-axis and a y-axis, and a secondary circle having a diameter equal to a radius of the axial markings. A first point on the secondary circle is aligned at the center of the central axis, and the secondary circle is configured to be rotatable about the first point. The secondary circle is configured to overlap and align with at least a portion of the axial markings as the secondary circle rotates about the first point.

An electronic watch having an altitude display mode of displaying an altitude, a compass display mode of displaying a direction, a barometric pressure display mode of displaying barometric pressure as display modes includes a dial face having an ALT area, a COM area, and a BAR area and a first pointer displaying the altitude display mode by pointing the ALT area, displaying the compass display mode by pointing the COM area, and displaying the barometric pressure display mode by pointing the BAR area. In the dial face, the ALT area, COM area, and BAR area are arranged in an order of the ALT area, COM area, and BAR area. In a turning direction of the first pointer, a distance between the ALT area and COM area and a distance between the COM area and BAR area are shorter than a distance between the ALT area and BAR area.

A watch movement comprising a retrograde mobile, an hours ring bearing an asymmetric internal toothing and driven by the retrograde mobile in order to display the current hour in a jumping way, a correction mechanism allowing the retrograde mobile to be corrected in both directions, a drive member that can be actuated by said correction mechanism and engages with said asymmetric internal toothing so that corrections of the retrograde mobile in the clockwise direction are transmitted to the hours ring, whereas corrections in the counterclockwise direction are not transmitted to the hours ring.

A watch dial includes a base material made of metal with a surface having unevenness formed by machining, a first coloring film formed at the surface of the base material by a dry plating method, and including a stack of at least one layer of an oxide film or a fluoride film, and at least one layer of a metal layer, and a second coloring film formed on a part of the first coloring film by coating. The watch dial includes unevenness formed on the base material, the first coloring film formed by a dry plating method, and the second coloring film formed by coating, and thus can achieve new and complex expression, and improve the aesthetics of the watch dial and the watch.

A dial for a timepiece, preferably a watch, the dial being provided with a relief portion which is made as an assembly of pieces on different levels, juxtaposed on a base, such that the relief portion is formed by the upper surfaces of the pieces. A method for manufacturing the dial with several separate pieces, the upper surfaces of the pieces being subjected to a polishing step and/or possibly an enameling step. The pieces are then cut along a defined contour and then assembled edge-to-edge on a base, so as to create the relief portion.
