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: The invention relates to a watch with a rigid casing-up, comprising: a middle (1); a bottom (2); a movement (3, 3bis, 3ter, 3quater, 41); and a casing-up ring (4, 4bis, 4ter, 42) in contact with the middle (1). The casing-up ring (4, 4bis, 4ter, 42) has an inner peripheral face (8, 17) and the movement (3, 3bis, 3ter, 3quater, 41) is secured to an outer peripheral face (7, 13, 18, 18bis), said inner (8, 17) and outer (7, 13, 1, 18bis) peripheral faces being in contact with each other in the Z and Z? regions thereof. Said watch is characterized in that it also comprises a tightening element (5, 5bis) provided for exerting pressure on the casing-up ring (4, 4bis, 4ter, 42) or the movement (3quater). The invention also relates to a method for casing-up such a watch.

Abstract: A mechanism for correcting a device for displaying time information is described. The display device includes a first display member for displaying current time information and a second display member for displaying stored time information, notably a second display member of the retrograde type. The mechanism includes an isolating device for isolating the first and second display members.

Abstract: A mechanism (3) for indicating and storing time information, including a transmission device (7) coupling a time information counting system (5) and a member (S?) for displaying time information adapted to display selectively current time information and stored time information, including: a cam (C); a lever device (L) including a lever (L1), a follower (L2) and a first elastic member (R) urging the lever and the follower into a particular relative position; the lever (L1) being kinematically coupled to the display member (S?) for displaying time information, the follower (L2) being urged against the cam (C) by a second elastic member (RL).

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 mechanism (3?) for correcting a device for displaying time information, the display device comprising a first display member (M) for displaying first time information and a second display member (M?) for displaying the stored first information, notably a second display member (M?) of the retrograde type, the mechanism comprising an isolating device (LI) for isolating the first and second display members.
