Definitions

  • the present invention relates to the field of watchmaking, more particularly the winding and time-setting mechanism of a watch.
  • the presence of the drum prevents the placement of the crown winding up because it would necessarily have to cross this drum to be able access the time setting mechanism.
  • the object of the present invention is to be able to access the mechanism of winding and setting the time by the back of the watch while ensuring good mechanical strength and tightness of the watch winder.
  • the object of the invention is achieved by the use of two crowns, one whose rotation allows the selection of the function, called selection crown, the other whose rotation allows the winding or modification of the time or date, known as the adjusting crown.
  • the rotary movement of the selection crown is transformed to inside the watch in a linear movement which acts on the mechanism function selection.
  • the rotation of the adjusting crown acts according to the function selected by the selection crown.
  • devices for this transformation for example a pinion and a rack or a cam and its cam follower.
  • the invention also applies to a function selection mechanism which, after selecting the last function, for example the calendar of the month, allows you to return to the winding position by rotation in the same meaning.
  • this function selection crown does not have a stop and can spin endlessly. This has the advantage of preventing any deterioration of the mechanism, even if the user has the wrong direction for the return to the reassembly position.
  • the present invention is applied to an existing caliber which has a conventional winding and time setting mechanism, that is to say by means of a winder usually placed on the middle of the watch.
  • the winding stem has been cut off and no crown is coming exceed the side of the middle.
  • This type of arm 6 training has the advantage over other modes drive, such as a rack, not to present any stop for rotation of the selection crown. By turning this crown in the same direction, we return to the reassembly position by traversing all the different functions.
  • the selection crown has marks on its periphery and thanks to a mark placed on the watch case indicates the selected function.
  • the first position is the barrel winding function
  • the second position corresponding to the modification of the calendar of the month
  • the third position corresponding to the modification of the hours and minutes.
  • FIG 2 which is a section along line A-A in Figure 1, we can observe the adjusting crown 1 which ends with the worm screw 3. This drives the winding pinion 4 and transmits the rotation to the mechanism winding and setting the time.
  • An "O-Ring" seal 9 seals between this crown and the back of the watch 11.
  • the selection crown 2 is complete by a lug 8 offset from the axis of that crown. This lug 8 is introduced into an opening 5 of the arm 6 and allows the latter to perform a displacement of an arc at its movable end, the end which leads longitudinally the winding stem.
  • the seal between this crown 2 and the the bottom of the watch 11 is provided by an "O-Ring" seal 10.
