A display system for a timepiece is disclosed. The system includes a mobile arranged to be driven by a drive source by first teeth provided on the mobile. The mobile includes second teeth including a teeth module of less than 0.05 mm, the second teeth being arranged so as to drive a display member either directly or indirectly.

A timepiece with a double-sided display, including a first display member and a second display member coaxial to the first display member and integral therewith with a first common arbor. The centers of mass of the first display member and the second display member are, in projection on a plane perpendicular to their common axis. The first display member and/or the second display member is arranged to display a visual animation, and is movable above a back, and, either above a mask partially and incompletely covering the back.

A timepiece with a double-sided display, including a structure including, on a first side, a first display member, and, on a second side, a second display member coaxial to the first display member and integral therewith with a first common arbor, the centres of mass of the first display member and the second display member are, in projection on a plane perpendicular to their common axis, aligned with the projection of the latter or coincident therewith, the first display member and/or the second display member is arranged to display a visual animation, and is movable above a back, and, either above a mask partially and incompletely covering the back, leaving a visible area contiguous with a hidden area wherein the back is invisible to the user, or between the back and the mask, moving above the visible area or the hidden area depending on its angular position with respect to the common axis.

A watch having a double watch-surface and a method for disassembling the double watch-surface are provided. The watch includes a casing, in which an abutting ring portion is convexly provided; a first watch-surface which is placed on the top of the abutting ring portion; a second watch-surface which is placed at the bottom of the abutting ring portion; an snapping ring, the inner ring of which is annularly provided with a pressing portion and a groove; and a transparent cover engaged onto the groove. The two snapping rings are respectively engaged with the top surface and the bottom surface of the casing. The snapping ring is disposed on the abutting ring portion through the plural engaging protrusions. The pressing portion is pressed against the first and second watch-surfaces. Through the adjusting and snapping assembly, effect of engaging and fixing the two snapping rings to the casing can be achieved.

The present disclosure provides a reversible watch with a secure and convenient flipping mechanism that facilitates quick and easy switching between two different watch faces. The mechanism comprises a timepiece block resting in and coupled to an outer frame by a pair of pivot joints about which it can rotate, and a set of ball bearings and corresponding indents that secure the timepiece to the frame when the time displays are aligned with the frame. The time displays are also separately controllable, allowing for users to conveniently switch between any two relative times.

A convertible smart watch including: a frame having a groove; a watch body having an analog watch unit on one side and a smart watch unit on the other side leaning against each back, which is designed to be inserted to the groove; and a supporting member supporting the watch body so as to be rotatable, wherein one side is combined to the frame with a hinge such that watch body may rotate with respect to the frame between a first position being inserted to the groove and a second position being protruded to the front of the frame by leaving from the receiving groove.

The invention relates to a display system for a timepiece, said system comprising a mobile arranged to be driven by a drive source by means of first teeth provided on the mobile. According to the invention, the mobile comprises at least second teeth including a teeth module of less than 0.05 mm, said second teeth being arranged so as to drive a display member either directly or indirectly.

A platform for displaying several mutually different horometric items of information, includes as many crowns as the horometric items of information to be displayed on the platform. Each of the crowns is arranged to receive an associated information support and is movable in rotation at a speed selected according to a horometric item of information displayed on the associated information support.

A centralized control unit for controlling an arm moving in a clockwise direction and in a counter-clockwise direction includes an arbor about which the centralized control unit pivots. The arm is integrally mounted on a toothed actuating wheel as an assembly, and the assembly is mounted to freely rotate about the arbor. The centralized control unit also includes a wheel to control the arm in the clockwise direction, a wheel to control the arm in the counter-clockwise direction, and a power wheel kinematically connected to an independent barrel to drive the arm.
