摘要： A timepiece display mechanism including a barrel with a spring between the arbor of a first wheel set driven by a drive wheel set, and a drum carrying a peripheral snail cam traversed by a feeler controlling the periodic jump of a display member, this drum carrying an peripheral finger outside the trajectory of this feeler, this first wheel set including an eccentric crank pin permanently guiding a groove to control the periodic back and forth motions of a pivoting anchor piece, which includes, on either side of an anchor piece axis, a beak and a stop for stopping or releasing this finger depending on the angular position of this anchor piece, the angular travel of each finger between its release by this beak and return to abutment on this stop defining the jump duration.

摘要： Timepiece mechanism for displaying the lunar day and the moon phase. The moon is represented by a sphere mounted on a meridian wheel and includes a first rotating element meshed with a drive mechanism, a second rotating element friction mounted on the first rotating element, a moon wheel set coupling the first rotating element to the meridian wheel, a transmission wheel with a jumper spring, a system for correcting the lunar day display via a first correction wheel bypassing the transmission wheel and including the meridian wheel, a system for correcting the lunar day display via a second correction wheel including the transmission wheel.

摘要： The device for pivoting an arbor about a determined axis includes at least one magnetic bearing including a magnet which exerts a force of attraction on a pivot, made of magnetic material, of the arbor. Further, the bearing includes a magnetic flux centring structure arranged between the magnet and the pivot, and a support for the centring structure. This centring structure includes a peripheral portion and a central portion resiliently connected to the peripheral portion by at least one connecting element, the central portion being formed of a highly magnetically permeable material and having smaller dimensions than those of the magnet. The peripheral portion is rigidly force fitted to the support so that the central portion is centred on the pivot axis.

摘要： Moon phase display mechanism including a control wheel driven by a movement, which control wheel drives a moon phase disc behind an aperture in a dial, and this mechanism includes: coaxial, superposed and permanently driven in opposite directions, a first phase indicator wheel carrying a first heart cam, and a second phase indicator wheel carrying a second heart cam, and this control wheel includes means for guiding a double lever comprising two arms, only one of which arms is arranged, at any time, to cooperate in contact with one of these second and first heart cams, each to display the moon phase visible in either the Northern or Southern Hemisphere, and to allow the moon phase disc to pivot in the appropriate direction for this hemisphere.

摘要翻译： 月相显示机构，其包括由运动驱动的控制轮，该控制轮驱动表盘中的孔后面的月相盘，并且该机构包括：沿相反方向同轴，叠加并永久地驱动;第一相位指示轮， 第一心形凸轮和携带第二心形凸轮的第二相位指示器轮，并且该控制轮包括用于引导双杠杆的装置，所述双杠杆包括两个臂，其中仅一个臂布置在任何时候，以配合接触其中之一 这些第二和第一心形凸轮，每个都显示在北半球或南半球可见的月相，并允许月相圆盘沿着该半球的适当方向枢转。
