Definitions

  • the present invention relates to a method of mounting a screw-down crown, such as a winding crown, on a watch case.
  • the invention relates to such a mounting method making it possible to index the position of a screw-down crown on a watch case so that a logo affixed to one face of said crown is always easily brought back to a determined position or orientation. after the crown has been unscrewed.
  • the invention also relates to a watch case provided with a screwed crown comprising a logo in which the logo is oriented in a determined manner.
  • a watch case provided with a screwed crown comprising a logo in which the logo is oriented in a determined manner.
  • the manufacture and assembly of crowns screwed onto watch cases are well known.
  • the methods of mounting these crowns have a significant drawback.
  • the known mounting methods do not make it possible to ensure that the crown is brought back in a determined orientation relative to the case after it has been unscrewed, which considerably affects the aesthetics of the case when a mark or a logo is affixed to one side of the crown. This situation is of course unacceptable when these crowns are fitted to luxury and high quality products.
  • the main object of the present invention is to remedy the drawbacks of the aforementioned prior art by providing a simple and economical method for mounting a crown comprising a logo or a mark, which systematically allows the crown to be brought back by screwing into a position. or a specific orientation after it has been unscrewed.
  • the subject of the invention is a method of mounting a screw-down crown on a watch case, characterized in that it comprises the following steps:
  • crown having an internal thread indexed with respect to a logo placed on the front face of the crown;
  • the mounting of the crown with indexed thread includes the following steps:
  • the invention also relates to a watch case comprising a screwed crown provided with an internal thread, the front face of said crown comprising a logo or a brand, an intermediate tube comprising an external threaded section intended to receive said thread, said intermediate tube being fixedly mounted in the box, the latter being characterized in that the internal thread of the crown is indexed relative to the logo or the brand and in that the intermediate tube is mounted in the box so that it can be angularly oriented relative to the box and fixed on the box in a determined angular position
  • the crown comprises on the side opposite to said front face an annular groove in which is fixedly mounted a ring provided with an internal thread.
  • the ring is welded to the crown.
  • the intermediate tube is mounted in a smooth hole in the box and is made integral with the box by means of a nut.
  • FIG. 2 shows an exploded view of the crown before the implementation of the method of the invention.
  • the screwed crown 1 comprises a first part formed by a head 3 having a front face 4 on which is affixed a logo or a mark 5 which, in the screwed position of this crown, has an angular orientation determined relative to the case 2 This first part is connected to the movement in a classic way.
  • the head 3 is provided on the side opposite to the front face 4 with an annular groove 7 which receives an internally threaded ring 8.
  • the ring 8 is positioned in the groove 7 using a template (not shown) in a way to index said thread 9 relative to the logo 5 and is immobilized in the groove 7 in said indexed position.
  • the indexing operation is preferably carried out using a camera and the immobilization is carried out by a welding operation, for example laser welding.
  • the logo 5 therefore has a determined and known angular position relative to the entry of the internal thread 9.
  • the crown further comprises a second part connected to the box 2. This second part comprises an intermediate tube 10 and a nut 11 intended to immobilize the tube 10 in a determined angular position on the box 2.
  • the tube 10 comprises two externally threaded sections 12 and 13 which cooperate respectively with the nut 11 and the indexed thread 9.
  • the tube 10 is mounted freely in a through hole 14 smooth of the box.
  • the tube 10 is then wedged using a template (not shown) to arrange the inlet of the thread 13 in an angular position such that when the crown 1 is screwed in abutment on the tube 10 said logo 5 is located in an angular position determined with respect to the box.
  • a template not shown
  • the crown can already be fully screwed onto the tube 10 during its positioning, the indexing then takes place not on the entry of the thread 13 but directly on the orientation of the logo before the tube 10 is blocked. using nut 11.
