20090086583 | ZERO RESET DEVICE FOR TWO TIME COUNTERS - Timepiece device for simultaneously resetting to zero two time counters, particularly for a chronograph mechanism, each of the two time counters pivoting about an arbour secured to a cam ( | 04-02-2009 |
20090147629 | CHRONOGRAPH CONTROL DEVICE - The present invention concerns a chronograph control device including a first, pivotably mounted lever, which is activated by a first push-button and whose movement in the direction of the first push-button is limited by a first stop member, and a second, pivotably mounted lever, which is activated by a second push-button and whose movement is limited in the direction of the second push-button by a second stop member. A spring is mounted on the second lever. | 06-11-2009 |

20130016590 | TIMEPIECE MOVEMENT COMPRISING A MODULE FITTED WITH A WHEEL SET MESHING WITH ANOTHER WHEEL SET PIVOTING IN A BASE ON WHICH THE MODULE IS MOUNTEDAANM Moulin; JulienAACI VollegesAACO CHAAGP Moulin; Julien Volleges CHAANM Villar; IvanAACI BienneAACO CHAAGP Villar; Ivan Bienne CHAANM Kaelin; LaurentAACI SonvilierAACO CHAAGP Kaelin; Laurent Sonvilier CHAANM Wyssbrod; BaptistAACI NidauAACO CHAAGP Wyssbrod; Baptist Nidau CH - Timepiece movement including a module fitted with a first wheel set meshing with a second wheel set, which pivots on a base on which the module is mounted. The movement includes a means of positioning the module formed by a cam, at least most of the periphery of which forms an Archimedes' spiral. The cam is arranged so as to allow the distance of centres between the first and second wheel sets to be adjusted, when the cam is rotated on itself about the centre of the Archimedes' spiral. The cam is preferably calibrated. The invention also concerns a method of adjusting the distance of centres between the two wheel sets using said cam to optimise the gearing efficiency of the two wheel sets. | 01-17-2013 |
20130128707 | TIMEPIECE ASSEMBLY WHEREIN A BOTTOM PLATE IS CENTRED AND SECURED RELATIVE TO A MIDDLE PART - Timepiece assembly ( | 05-23-2013 |
20140211596 | TIMEPIECE BARREL ASSEMBLY WITH REDUCED CORE DIAMETER - A timepiece barrel assembly, including a barrel mainspring mounted between a barrel drum and a receiving surface of a barrel core coaxial to the drum. The spring is made of a multiphase, cobalt-nickel-chromium based alloy, having a Young's modulus of between 200 and 240 GPa and a shear modulus of between 80 and 100 GPa, and having a width to thickness ratio of between 9 and 21, and the maximum radius of the steel or stainless steel core relative to its pivot axis is less than nine times the maximum thickness of the spring, and the barrel assembly includes, on the spring or the drum, a mechanism limiting longitudinal clearance, towards the pivot axis, between the drum and the mainspring. | 07-31-2014 |
20140376338 | TIMEPIECE MOVEMENT HAVING A BARREL WITH REDUCED CORE DIAMETER - A timepiece movement, including a plate and a bridge carrying a barrel including a barrel mainspring between a drum and a receiving surface of a core and a cover fixed to the drum. The spring is made of a multiphase, cobalt-nickel-chromium based alloy, having a Young's modulus of between 200 and 240 GPa and a shear modulus of between 80 and 100 GPa, and having a width to thickness ratio of between 3 and 23, and the maximum radius of the steel or stainless steel core relative to the pivot axis is less than nine times the maximum thickness of the spring. The movement further includes a mechanism limiting shake including a shim-washer independent of the core and guided by a shoulder of the core. | 12-25-2014 |
20150016231 | MICROMETRIC ADJUSTMENT OF THE ENDSHAKE OF A TIMEPIECE WHEEL SET - Device for the micrometric endshake adjustment of a timepiece wheel set in an axial direction in relation to a structure, including a pivot bearing for this wheel set defining an axial stop member for this wheel set in this axial direction. | 01-15-2015 |
20150078145 | BELOW DIAL HAND FITTING - A timepiece movement driving at least one output arbor for receiving an indicator displaying a physical or temporal magnitude facing and above a complementary indicator or a dial, the complementary indicator or dial being arranged on a local reference or bearing surface included locally in the movement about of each the output arbor of the movement, or being arranged on the local reference or bearing surface. The output arbor includes, on a side of a local reference or bearing surface thereof, a free end which is either recessed or flush with respect to the local reference or bearing surface thereof. | 03-19-2015 |
