Abstract: An escapement (1) comprising: a roller (5), a first mobile escapement part (2) comprising first escapement teeth (22) and a second mobile escapement part (3) comprising second escapement teeth (32), a means (29, 39) for mechanically coupling the first mobile escapement part to the second mobile escapement part, and an anchor (4) carrying a first and second pallet stone (42, 43), the roller comprising a third impulse pallet stone (52) cooperating with the first escapement teeth and a fourth impulse pallet stone (53) cooperating with the second escapement teeth.

Abstract: The escapement racks for the hour (11), for the quarter-hour (10) and for the minutes (9) on the minute-repeater are mounted such that the same pivot about a common axis (14), with the escapement racks for the hour and the quarter-hour on one side, and the racks for the quarter-hour and for the minutes on the other side connected by a unidirectional drive connection having a ratchet (15, 17), a toothed pawl (10a, 9a) engaging with the ratchet, a banking pin (10b, 9b) and a cam (16b, 18b) to enable selective engagement of the ratchet with the pawl teeth. The end of the motor spring is kinetically secured to the two separate sets of activating pawl teeth (13a, 13b) for the first chime lift (21), with the first set of teeth (13a) for the hour chime, and the second set of teeth (13b) for chiming quarter-hours and minutes.

Abstract: The invention concerns a timepiece comprising, in addition to the usual hour and minute hands, a disc on which there is represented a circular map of the world divided into time zones and a pointer designating one particular time zone corresponding to a time chosen by the user. This timepiece is distinctive in that in that: the disc (1) is able to turn on itself; the pointer (2) is fixed; and a pushbutton (4) may be provided that is connected to said disc (1) so that each depression thereof causes the disc (1) to turn through an angle corresponding to one time zone (f).

Abstract: This pushbutton device for controlling the start/stop and resetting functions of a chronograph mechanism comprises two control pushbuttons able to slide between two limit positions, elastic return means which constantly tend to keep these pushbuttons in their outward limit positions, and a control rocker which pivots about a pivot. The control rocker is situated between the pushbuttons, the latter being, in their outward limit positions, simultaneously in contact with the control rocker, keeping it in a middle position between the limit positions of its pivoting, which correspond to the movement of the pushbuttons to their respective inward limit positions.

Abstract: Writing implement (1) of longitudinal axis (2), comprising an essentially tubular body (30), a retractable nib (10), an actuator (35) and a retractor (40) for retracting said nib (10). It also comprises a guard member (20) comprising a plurality of guard petals (21), each mounted so as to be able to move between an open position and a closed position about a pivot axis (22), and a movement transfer mechanism (31). This last is integral with said body (30), is synchronized by said retractor (40), and is connected to said guard petals (21) to transfer the movement applied to the actuator (35) into a pivoting movement of said guard petals.

Abstract: This adjustment device comprises: a first adjustment member with a fixed position relative to the longitudinal axis of the strap; first guide means connected to this first adjust member; a connecting member engaged on the one hand with said first guide means and on the other hand with the other of the strap halves; second guide means for rotational guidance, connected to said first adjustment member; a second or manual adjustment member having guide means shaped to engage with said second guide means of the first adjustment member; and means for transmitting movement between said second or manual adjustment member and said connecting member to turn the circular movement of the second or manual adjustment member into a rectilinear movement of said connecting member.

Abstract: A storage device comprises a first seconds wheel, engaging with a mainspring, and a second seconds wheel, a setting wheel for connecting these two seconds wheels, a yoke on which said setting wheel is pivotably mounted, the pivot axis of this yoke and that of the second seconds wheel being coaxial, a stop wheel kinematically linked with said first seconds wheel, a finger fixedly connected to said yoke, a storage spring for exerting upon said yoke a force tending to separate said finger from said stop wheel, whereas the force exerted upon said setting wheel by said mainspring serves to press said finger against said stop wheel, so that the latter is wound to the point where a tooth of said stop wheel abuts against said finger.
