Patent number: 11886147Abstract: A variable timepiece display mechanism includes a resilient hand with a drive pipe integral with a single-piece flexible strip including flexible segments joined at tips, a first segment thereof extends between the first pipe and a first tip. The mechanism also includes a driver for driving the pivoting of the pipe, and a stressor for stressing the first flexible segment in order to vary the position of the first tip relative to the output axis, as a function of the forces applied to the flexible strip. The drier and/or the stressor includes a first shaped gear train and/or a second shaped gear train in order to accelerate, stabilize the speed of, or slow at least the pipe over a part of the angular travel thereof.Type: GrantFiled: July 24, 2019Date of Patent: January 30, 2024Assignee: Montres Breguet S.A.Inventors: Marc Stranczl, Jan Pittet

Patent number: 8770833Abstract: The musical or striking watch includes a watch case, which is formed of a middle part and a back cover, provided with side apertures and removably secured in a sealed manner to the middle part. A crystal closes the case in a sealed manner. A timepiece movement is held inside the watch case and provided with a striking mechanism that can be actuated at determined times to produce notes or music. The watch further includes at least one removable acoustic radiating membrane, which is arranged in the watch case. The removable membrane includes, in a central position, a retaining member. This retaining member is arranged with play in a housing in an inner stop member of the back cover. Owing to the cooperation between the retaining member and the stop member, the bending of the membrane is limited following excess pressure or vacuum pressure according to environmental conditions.Type: GrantFiled: March 20, 2012Date of Patent: July 8, 2014Assignee: Montres Breguet SAInventors: Fabio Sciascia, Jan Pittet, Beat Gilomen, Dave Mangin

Patent number: 8588034Abstract: A timepiece wheel governor for regulating the pivoting speed (?) of a wheel set, about a pivot axis, including a pivoting inertia-block. It includes a spring to return this block towards this axis, and, when the wheel set pivots at a lower speed than a reference speed (?c), this block remains confined within a first volume of revolution, and, when the wheel set pivots at a higher speed than the reference speed (?c), this block is engaged, in one peripheral portion thereof, in a second volume contiguous with and external to the first one, this peripheral portion cooperating in this second volume with a regulator arranged to brake the wheel set and return the pivoting speed (?) thereof to the reference speed (?c), and to dissipate the surplus energy.Type: GrantFiled: February 9, 2012Date of Patent: November 19, 2013Assignee: Montres Breguet S.A.Inventors: Jan Pittet, Jean-Jacques Born, Thierry Conus, Eric Goeller, Patrick Ragot, Sylvain Marechal, Davide Sarchi, Jérôme Favre

Patent number: 8356929Abstract: The timepiece movement (1) includes a karussel (4) whose platform carries an escape wheel that cooperates with a balance (7). The platform is driven from the time display mechanism associated with a time-setting mechanism (32). The escape wheel is driven directly from the gear train. In addition to compensating for differences in rate due to gravity, the karussel of the invention proposes a new, complementary role: that of time indicator.Type: GrantFiled: October 20, 2009Date of Patent: January 22, 2013Assignee: Montres Breguet S.A.Inventors: Alain Zaugg, Jan Pittet
