摘要:
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 centers between the first and second wheel sets to be adjusted, when the cam is rotated on itself about the center of the Archimedes' spiral. The cam is preferably calibrated. The invention also concerns a method of adjusting the distance of centers between the two wheel sets using said cam to optimise the gearing efficiency of the two wheel sets.
摘要:
There is disclosed a method for manufacturing and mounting electric contacts for control members of small dimensions, particularly for control members used in the horological field. This method includes the following steps: a) stamping and pre-shaping a plate of electrically conductive material for forming an intermediate base plate including a support structure and a plurality of electric contact strips still mechanically connected to said support structure by a plurality of points of attachment, each electric contact strip including a base and a flexible extension connected to said base to form a mobile part of an electric contact that can be actuated by a control member, b) positioning the intermediate base plate on a first support piece electrically insulated from said electric contact strips, c) fixing onto said first support piece a second support piece electrically insulated from said electric contact strips such that each of said electric contact strips is held between said first and second support pieces via its base and d) breaking said plurality of points of attachment connecting the plurality of electric contact strips to said support structure such that all of the electric contact strips are made independent and electrically insulated from each other.

The dial (3) is secured onto a lower element (10) of the case, preferably the casing ring. The lower element (10) includes at least two through passages (12) each having a first part (13) forming an orifice (14) on the dial (3) side separated from a second part (17) on the opposite side, by a neck portion (15), the whole of the first part and at least a portion of the second part of said passages (12) being filled with an adhesive material (19) having a strong power of adhesion to at least the material forming the lower face of the dial (3).

A timepiece and a case intended to fit such a timepiece. This timepiece comprises a clockwork movement (12), a case (2) consisting of a caseband (4) and a back cover (6) forming a housing (10) for receiving said movement (12), means for axial positioning (25, 26) and means for lateral positioning (P) of the movement (12) with respect to the case (2). The axial positioning means are arranged in a peripheral region of the housing (10) and may allow a lateral play along a support plane (27). The lateral positioning means (P) are arranged respectively on the back cover (6) of the case (2) and on a lower part (14b) of the frame (14), preferably in the form of a central stud (6) fixed to the back cover (6) and engaged with an axial play in an opening (38) of the movement.

The watch case includes a back cover (2), a middle part (3) and a bezel (4) closed by a crystal (5) delimiting together a space in which a watch movement (1) is housed for an analogue or digital time display on a dial (6) arranged below the crystal (5). It is characterized in that the bezel (4) is made of metal and has locally a ring (14) of sufficient thickness to include in its lower portion a first series of threaded holes (11) for screwing in a first series of screws (10) for fixing the movement (1) onto the bezel (4) and a second series of threaded holes (21), offset angularly with respect to the first series, passing through the movement (1), and intended for screwing the back cover (2) into the lower part of the bezel (4).

The watch (1) in accordance with the invention comprises positioning means for the movement in the case. The positioning means comprise two blind holes (30) arranged in the case (6) and two centering elements (32), these latter having a first part driven into the blind holes and a second part (36) projecting from the case and cooperating with openings (38) provided in the movement.
