Abstract: The invention relates to a horological device, in particular a horological movement or timepiece, comprising a winding mechanism and at least one mechanism for correcting at least one indicator member. According to the invention, the aforementioned mechanisms can be actuated by a control stem that can occupy at least two axial positions, each corresponding to the actuation of one of the mechanisms, said control stem (T) comprising: a winder pinion (5) that can engage with the winding mechanism; and a sliding pinion (6) that can be moved axially, both with respect to the control stem (T) and with respect to the frame of the horological device, and can engage with the correcting mechanism.

Abstract: A device (100; 200) for resetting to a predetermined position an indicator member (2, 13; 22) indicative of a parameter connected with time, notably a “flyback” device, the indicator member being kinematically linked to a drive mobile (15; 35), the device comprising an energy accumulator (9) and a return element (1; 21) for returning the indicator member indicative of the parameter connected with time to the predetermined position, the return element being powered by energy from the accumulator, the energy being supplied to the energy accumulator by a user via a control member (4) for resetting to the predetermined position, the control member being able to be manipulated by the user.

Abstract: A balance wheel for timepiece movement, which obeys the following condition: D5·f/I?20·10?2m3kg?1s?1 where D is the diameter of the balance wheel, f is the frequency and I is the moment of inertia.

Abstract: Device (300; 200) for displaying the time, comprising a time-display member (A1, A2) and a switchover mechanism (100) allowing the time-display member to switch between a first time zone and a second time zone. This switchover mechanism comprises: a first heart piece (3) capable of rotating; a first lever (1) having a first end (1a) designed to collaborate with the first heart piece (3) with a view to causing the display member (A1, A2) to indicate the time in the first time zone; a second lever (2; 42) designed to cause the display member (A1, A2) to indicate the time of the second time zone; a two-position selector member (5) collaborating with the first lever (1), and a control member (P) allowing selection of the first or the second time zone for display. The two-position selector member (5) is designed to collaborate directly with a second end (1b) of the first lever (1).

Abstract: This device for displaying time periods comprises a display element (A), an indicator component (1), a drive component (3) for driving the indicator component (1), an instantaneous-jump cam (6) engaged with the drive component (3), a drive mobile (5) for driving the cam (6) and correction means (4) for coming into direct engagement with the indicator component (1). A one-way connection device (3b, 11, 12) connects the drive mobile (5) to the cam (6). The drive component (3) is engaged with the cam (6) by elastic return means (3d) and guidance means (3b) defining a degree of freedom of the drive component (3) in order to allow the indicator component (1) to move the drive component (3) against the elastic return means (3d) when the latter occupies a position interfering with the movement of the indicator component (1) by the correction means (4).

Abstract: This timekeeper comprises a first timer (4), means (12) for connecting it selectively to the train of the timekeeper (T), a second timer (5), a synchronous coupling between the first (4) and second (5) timers, and fly-back means (13, 13?, 9, 11) for said timers (4, 5). An auxiliary motive source (10?) is in a driving relationship with the second timer (5) and a one-way coupling (6a, 7a) is situated between the first (4) and second (5) timers to regulate the speed of movement of the latter at a predetermined ratio with the speed of movement of the first timer (4) while allowing one-way relative movement of the first timer (4) relative to the second (5) when the latter is in the stop position and one-way relative movement in the opposite sense of the second timer (5) when the first timer (4) is in the stop position.
