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 drive member and a mechanism for a timepiece including such a drive member includes at least two monolithic units stacked and connected in series, each of these units including a hub and a rim which are connected by at least one elastic arm.

A timepiece mechanism includes a first energy source with a regulating member, a second independent energy source, a control member driven by the second energy source, and a blocking device controlled by the first energy source to block the second energy source and release it to allow the control member to be displaced by jumps powered by the second energy source. The blocking device includes first and second mobile parts kinematically interconnected, the first mobile part including a drive device, the second mobile part including a stopping device; a rotating drive member connected to the first energy source and cooperating with the drive device to displace the mobile parts, alternately in opposite directions; and a rotating blocking member connected to the second energy source and cooperating with the stopping device to be blocked by the second mobile part and released at the determined times by second mobile part movement.

Timepiece wheel set with a unidirectional wheel rotating in only one direction in cooperation with a ratchet wheel, which is movable inside a ratchet wheel chamber, comprising a click that rotates integrally with this wheel, which forms a one-piece component comprising at least one spring-arm, at the end of which, on a first side, a beak cooperates directly with the toothing of a ratchet wheel in an operating position in which this spring-arm is free, and on a second side, a first hook can cooperate with a second hook of complementary shape, comprised in this one-piece click, in a rest position in which this spring-arm is in an extended position, the elasticity thereof allowing this first hook to be hooked or unhooked with respect to this second hook by the action of an operator, by maximum elongation of this spring-arm and/or by the tilting of this end.

A mechanical horological movement (1) including at least one barrel system (2) for driving a set of wheels and power reserve detector. The detector (10) includes a control wheel (3) disposed opposite the cage of the barrel system (2) and is rotated by a complementary wheel (8) at the differential output to determine a power reserve level. An aperture (13) has a first end (21) to define a complete charge of the barrel system and a second end (22) to define a complete discharge. A lever (4) is rotatably mounted about a lever axis parallel to the axis of rotation of the control wheel. A contact element (5) disposed in the aperture contacts the second end during a zero power reserve indication. A portion of the lever contacts a component of the movement to stop its operation when power reserve indication is at zero.
