Publication number: 20240036520Abstract: Disclosed is a display device for a timepiece movement including: an hour display wheel for a predefined time zone; and a chassis pivotable to cooperate with indications that are static relative to the frame of the timepiece movement to display information, the respective angular positions of the chassis and of the hour display wheel being indexed relative to each other so the angular position of the chassis is associated with the display of information relating to the predefined time zone. The device further includes a selection mechanism arranged: to rotate the hour display wheel, responsive to a predefined action by a user, between first and second positions associated with respective first and second time zones; and to simultaneously rotate the chassis in steps so that the chassis moves from a first position, associated with the first time zone, to a second position, associated with the second time zone.Type: ApplicationFiled: December 3, 2021Publication date: February 1, 2024Inventors: Jean-François MOJON, Xavier CLEMENT, Thomas FUNDER-NIELSEN

Patent number: 7742363Abstract: Mechanical digital display including at least one digit consisting of at least seven segments (1) for the display of alphanumeric characters. Each segment (1) is a body in the form of a bar (1) which can pivot about its longitudinal shaft (3), the said bars (1) having at least two areas resembling a first and a second strip (1?, 1?). These have different appearances, and are arranged along the length of the bar (1) in such a way that the orientation of the bar (1) by rotation about its longitudinal shaft (3) enables either the first or the second strip (1?, 1?) to be made visible. The display of an alphanumeric character is achieved as a result of the dissimilarity of the appearance between the first and second strip (1?, 1?) of the set of bars (1). The pivoting of one or more bars (1) to replace the first strip (1?) with the second strip (1?) or vice versa generates the display of different alphanumeric characters.Type: GrantFiled: September 18, 2007Date of Patent: June 22, 2010Assignee: De Grisogono SAInventors: Fawaz Gruosi, Jean-François Mojon

Patent number: 7458717Abstract: An escapement for a timepiece movement includes a toothed escape wheel, a balance and a detent respectively pivoted on rotation axes. The detent supports a pallet lock that interacts with the first tooth of the escape wheel along a certain length of penetration in order to block it in an idle phase during which the balance executes a free arc of oscillation. An impulse pallet rotationally driven by the balance interacts with a second tooth when the detent is pivoted in order to release the escape wheel, this wheel turning by a forward pitch before being blocked again by the pallet lock by interaction with the second tooth. The escapement also includes a limiting plate, which is coaxial and rotationally secured to the balance, has a periphery including a substantially circular main portion and a cutout positioned facing the pallet lock in the release phase.Type: GrantFiled: September 29, 2006Date of Patent: December 2, 2008Inventors: Peter Baumberger, Jean-François Mojon

Patent number: 7347618Abstract: An automatic pawl winding mechanism for a watch movement has a rotor solidly attached to a rotor wheel and oscillating about the axis of a rotor pivot, a pawl wheel to which an oscillating motion of rotor is transmitted by the rotor wheel being pivoted about the axis of a pawl wheel shaft, at least one pawl being eccentrically attached to the pawl wheel shaft, and an automatic wheel cooperating with the pawl or pawls. The oscillating motion of the rotor wheel is thus transformed into a unidirectional rotary motion of the automatic wheel, and this rotary motion is transmitted to a ratchet wheel via a transformation gear train. The rotor, the gear train from the rotor with rotor wheel to the pawl wheel with the pawl or pawls is mounted on an independent rotor bridge while no other organ of the mechanism is mounted on this bridge.Type: GrantFiled: December 30, 2005Date of Patent: March 25, 2008Assignee: Richemont International S.A.Inventors: Jean-François Mojon, Norberto Perucchi

Patent number: 6997602Abstract: The present invention refers to a constant-force device suitable for being integrated into a movement of watches, particularly wrist watches, with an indirect-second mechanism having an intermediate second pinion (14) driven by a second wheel (9) of the movement, and an indirect-second wheel (15). The constant-force device comprises a tensioning module (4, 5, 6, 7, 8), a cam (2), a lever (11), and a stop wheel (13). The stop wheel (13) of the constant-force device is mounted on the intermediate second pinion (14) of the indirect-second mechanism.Type: GrantFiled: October 28, 2003Date of Patent: February 14, 2006Assignee: Richemont International S.A.Inventors: Jean-François Mojon, Kilian Eisenegger
