It is therefore understood that the annular piece 61 is mounted against the casing ring 45 at the upper part of the face 63 and the face 71 rests on the underside of the thread 49 of the movement 25.
  • the face 63 also has recesses 68 and 66 for releasing the space around respectively the mechanical controls 53, 55 of the chronograph and the hole 54 for controlling the time setting device and, possibly, the date device. It is therefore understood that the recesses 68, 66 make it possible to receive the rods respectively of the pushers 30, 34 and the crown 32.
  • each recess 68 is also intended to form a flange by insertion of each push rod 57, 30, 34 at its second annular recess 59.
  • the annular piece 61 also comprises two grooves 70 made at its inner face 67 to provide clearance for the flared end 75 of each rod 57.

  • the bezel 24 will be manufactured by mounting the ice 35 with the help of, for example, a seal.
  • the movement 25 will be manufactured by mounting in particular the casing ring 45, the dial 43 and the needles 41.
  • the bottom 26 will be manufactured including mounting the seal 40 and the ice 36 with the help, for example, of another seal.
  • the middle part 22 will be manufactured by mounting in particular the rings 37, 39 with the help of, for example, a seal and the holes 29, 31, 33.
  • step 5 of the method 1 the movement 25 prepared in phase 4 is slid into the middle part 22 prepared during phase 8 until the respective shoulders 44 and 28 come into contact.
  • the guidance of step 5 is improved by the interaction of the positioning pin 46 present on the casing ring 45 in the recess 50 of the inner wall of the middle part 22.
  • the casing ring 45 and therefore the movement 25 is positioned in the middle part 22 at an angle ⁇ with respect to the axis A1 and a predetermined depth.

  • Step 9 the bezel 24 prepared during phase 2 is mounted on the middle part 22 in order to close the upper part.
  • Step 9 thus comprises a first phase 10 intended to bring the flange 51 against middle part 22 in partial overlap of the dial 53.
  • the guidance of the phase 10 is improved by the interaction of the positioning pin 46 present on the casing ring 45 in the groove 52 made on the base of the flange 51.
  • the flange 51 is positioned in the middle part 22 at an angle ⁇ with respect to the axis A1 and a predetermined depth.
  • the fourth step 9 continues with the second phase 12 intended to bring the seal 38 against the ring 37 of the middle part 22 and then by a third phase 14 intended to drive the telescope 24 against the ring 37 by means of the seal 38.
  • a fifth step 11 the pushers 30, 34 are mounted against the movement 25 by passing successively through the holes 29, 33 of the middle part 22, the notch of the casing ring 45 so as to face with the controls 53 and 55 of the movement 25.
  • the sixth step 13 of the method 1 is intended to mount the annular piece 61 against the casing ring 45.
  • the sixth step 13 is performed by counteracting the expansion force of the springs 74 to maintain the pushers 30, 34 against the controls 53 , 55 then sliding the piece 61 against the inner wall of the middle part 22 to match the recesses 62, 64, 66, 68, 70 with the reliefs of the casing ring 45 and the rods of the pushers 30, 34 and the crown 32.

  • this step 15 also makes it possible to compensate for the manufacturing dispersions of different constituents. Indeed, as explained above, the deformation means 72, 73 will allow when driving the bottom 24 against the ring 39 to selectively crash by approaching said bottom 24 to adapt the final assembly to the actual dimensions of the room d watches that vary due to manufacturing dispersions.
  • the manufacture of the timepiece is thus complete.
  • the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art.
  • the movement does not limit to an automatic chronograph movement, other types of movement including a net 49 are possible.
  • the box 23 is partially closed, that is to say it has a bottom or a single-piece bezel with the middle part.
  • the case could be replaced by a box kept closed by the telescope only.
  • the case could be replaced by a box kept closed by the bottom only.
