A timepiece having multiple springs while reducing the plane size of the movement. The timepiece has a first barrel including a first barrel arbor, a first spring, and a first barrel wheel; and a second barrel including a second barrel arbor, a second spring, and a second barrel wheel, disposed to a position not superimposed with the first barrel in a plan view from the axial direction of the first barrel arbor and the second barrel arbor, and having rotation of the first barrel transferred thereto; a planetary gear mechanism having a display pivot that turns in a first direction when rotation of the first ratchet wheel that turns in unison with the first barrel arbor is transferred, and turns in a second direction opposite the first direction when rotation of the second barrel wheel is transferred, and is disposed to a position not superimposed with the first barrel and the second barrel in plan view; and a power reserve wheel train including multiple wheels that transfer rotation of the first ratchet wheel to the planetary gear mechanism, and having one of the multiple wheels axially supported by the second barrel arbor.

A pointer including a pointer body formed of synthetic resin, and a pointer attachment section formed of a material harder than the synthetic resin and provided in a rotation center portion of the pointer body, in which the pointer attachment section comprises a large-diameter section to which the pointer body is fixed and which includes a positioning section, and a small-diameter section which is provided coaxially with the large-diameter section and to which a pointer shaft is attached.

A date calendar display mechanism driven via a kinematic chain by a horological movement of a timepiece. A first and second date indicators, the first date indicator remaining still during a 24-hour period separating the passage from the last day of a month having 31 days to the end of the first day of the following month, the kinematic chain including a wheel continuously engaged with the horological movement and having a toothing via which the wheel meshes with a pinion which contributes to driving the first indicator, the wheel being, at one point, devoid of teeth such that, during the above 24-hour period, the wheel does not mesh with the pinion and remains still. A dual jumper pivots about an axis with a first beak via which it is engaged with a toothing of the first date indicator and, at a second beak via which it is engaged with a toothing of the pinion, the dual jumper being elastically held engaged with the first date indicator and with the pinion.

An analogue information display system for a watch provided with a mechanical movement includes a display dial including a plurality of apertures, a moving display part supporting graphical representations, disposed in such a way that the graphical representations supported thereby appear in the plurality of apertures in order to generate the information, and an indicator member configured so as to designate a piece of information generated in an aperture to be notified to the wearer of the watch.

Timepiece calendar device (100) including a first display disk (1) for displaying dates having a first face (11) bearing date indications (10) and mobile about an axis (A), and a second display disk (2) for displaying days having a second face (21) bearing day indications (20) and mobile about the axis (A), the first and second disks being such that the first and second faces are coplanar, the second face being disposed around the first face.

A timepiece calendar system (100) including: a date mobile (1); a first device (3) for indexing the position of the date mobile; a second device (4) for indexing the position of the date mobile; an element (70, 3b, 4b, 40) for activating and deactivating at least one of the first and second indexing devices, the indexing of the date mobile by one or the other of the first and second indexing devices being mutually exclusive.

A horology calendar system (200) including:a date wheel (1);a month cam (300); anda kinematic connection element (8) arranged so that the date wheel allows the driving of the motion of the month cam. Optionally, the kinematic connection element is arranged so as to allow the driving of the month cam by at most 1/n of a step while the date wheel is driven by one step, where n is a natural integer greater than 1.
