A timepiece, such as a watch, having a case, movement having an axis located within the case, gears connected to the movement, and one or more hands which may be driven by one or more gears. The gears are rotatably connected to a gear plane and are driven by the movement driving an axis extending through the gear plane. The gear plane has several connection points, such as perforations, indentations and/or protrusions, for the connection with the gears and with the hands. The gears drive the hands of the timepiece, which also include gears. The gears over the gear plane may be placed in one or more configurations to drive the hands.

An electronic tourbillion clock including a clock case having a plurality of high-resolution digital displays that extend around an outer circumference of the clock case as an indicator of hours. A seven segment display is located within the clock case as an indicator of minutes elapsed within an hour. A microcontroller determines the current time and other chronological indications depending on the output signals generated by a position of a tourbillon mechanism disposed in the clock case. A sub-circuit is disposed within the clock case and interconnected with the microcontroller for creating a plurality of distinctive sound patterns directed through one or more speakers in response to the output signals generated by the position of the tourbillon mechanism.

A decorative element for watches, comprising: a framework comprising arms (12) delimiting a plurality of decorative areas (Zi) and forming support elements, and a plurality of decorative components (20) fixed to the arms of the skeleton, each decorative component occupying a decorative area.

A timepiece includes a movement and a dial. The movement includes a first hand shaft to which a first hand is attached, a second hand shaft to which a second hand is attached, and an escapement speed control mechanism including a balance and a balance bush configured to support the balance pivotally. The dial includes a lower plate and an upper plate. The lower plate includes a lower plate ring portion and a frame portion. The upper plate includes an upper plate ring portion and a bridge portion. A lower plate opening is formed in the lower plate. An upper plate opening is formed in the upper plate. At least part of the frame portion is provide below the upper plate opening. At least part of the lower plate opening is provided below the upper plate opening. The bridge portion includes a first through hole and a second through hole into which the first hand shaft and the second hand shaft can be inserted, respectively, and a third through hole formed at a position overlapping with the balance bush in plan view.
