A clockwork movement includes a mechanical energy source, a first regulating part and a first escapement, which are connected by a first gear-train to the energy source, and a second regulating part and a second escapement, which are connected by a second gear-train to the energy source. The first gear-train, the first escapement () and the first regulating part () define a first assembly. The second gear-train, the second escapement and the second regulating part () define a second assembly. At least one differential gear is arranged to provide a kinematic connection between the first assembly and the energy source and between the second assembly and the energy source.

Timepiece movement and timepiece including such a movement

A device for displaying multiple times, includes a first time-displaying member () and a second time-displaying member () constituting first elements, and a first indicator for indicating at least one time on the first time-displaying member () and a second indicator for indicating at least one time on the second time-displaying member constituting second elements, wherein the first () and second () time-displaying members have a common axis. The first and/or second indicator for indicating at least one time is arranged between the first time-displaying member () and the second time-displaying member (), and the first and/or second indicators are mounted so as to be rotatable about the axis relative to each other at the same rotational speed, wherein the time that can be displayed on the first time-displaying member () is different from the time that can be displayed on the second time-displaying member ().

Device for displaying multiple times

A timepiece includes: a frame; a mobile body of a finishing gear train; and a tourbillon mechanism including a holder supporting a balance and at least one escapement. The tourbillon mechanism includes: an outer ring rotatably mounted onto the frame about a first axis; at least one inner ring inside the outer ring and rotatable relative to the outer ring about a second axis, the holder being pivotably mounted in the inner ring and secured to a shaft around which the inner ring is freely and rotatably mounted about a third axis; a first toothed member mounted onto the frame; a first pinion secured to the shaft of the holder to engage with the first toothed member to rotate the holder; and a unit driving the inner ring, engaging with the movable body of the finishing gear train and arranged to move the inner ring and, consequently, the outer ring.
