  • 1 is a crown, which is screwed onto a crown or Adjustment shaft bushing (also tube), which in Figure 1 with the interrupted Lines 2 is indicated, can be sealed by screwing.
  • the crown 1 consists essentially of the two-part crown body 3 and Actuating shaft 4, which cooperates with the clockwork in the usual way. Furthermore, a compression spring 5 is provided which between the control shaft 4 and the Crown body 3 acts and prestresses it in the longitudinal direction L of the actuating shaft 4, and in a working state in which the crown body 3 is in operative engagement with the control shaft 4 is.
  • Figure 1 shows the crown 1 in its tube 2 on the watch case 26 (FIG. 6), in which the crown body 3 is out of engagement with the actuating shaft 4 against the action of the compression spring 5. With L the longitudinal axis of the crown is designated in FIG. 1, which is also the axis of the crown Crown body 3 and the control shaft 4 is.
  • the crown body 3 is made in two parts, consisting of the crown body part 3 'and the crown body part 3 ".
  • the part 3' shown in the figures 2 and 3 is shown again in detail, is essentially sleeve-like with a Knurling 6 formed on a circular cylindrical peripheral or handle surface and has a first circular-cylindrical, open to an end face of part 3 ' Recess 7 with bottom surface 7 'and an open to the other end, also circular cylindrical recess 8 with bottom surface 8 '.
  • the recess 8 has a diameter smaller than the diameter of the recess 7 and is with provided with an internal thread 9, with which the crown body 3 on an external thread the tube 2 can be screwed on.
  • opening 10 provided with a deviating from the circular shape Cross-section is formed, in the embodiment shown with a Hexagonal cross-section, the cross-sectional dimensions of the opening 10 being smaller are as the cross-sectional dimension or the diameter of the recess 8.
  • Am Transition from the recess 8 to the opening 10 is the recess 8 with a Provide undercut 11 in which, when the crown 3 is fitted, an annular seal 12 is housed, which is supported against the bottom surface and at the watch case screwed crown 1 rests against flange 2.
  • the insert or part 3 is essentially hood-shaped, namely with a circular cylindrical peripheral surface 13 and a convexly curved End face 14. Furthermore, in part 3 "is a circular cylindrical and to which End face 14 opposite end face 15 is formed with open recess 16, whose axis is 3 aligned with the longitudinal axis L when the crown is fitted.
  • the Recess 16 forms at its closed end adjacent to the end face 14 a seat 16 'for one end of the compression spring 5. As shown in Figure 1, the Recess 16 a diameter that is larger than the largest Cross-sectional dimension of the opening 10.
  • the part 3 " is in the recess 7 of part 3 'with the assembled crown 1 open side of the recess 16 used in advance and there in a suitable manner attached, for example by a press fit. Furthermore, an additional Ring seal 17 the transition between the two parts 3 'and 3 "sealed.
  • the control shaft 4 has on its protruding from the crown body 3 and with the Clockwork connected section 4 'a circular cylindrical cross section. With In this section 4 ', the adjusting shaft extends through the recess 8 and at the state of the crown 1 shown in Figure 1, in the (state) none drive connection between the crown body 3 and the control shaft 4th exists, also through the opening 10.
  • the section 4 ' is adjoined by the adjusting shaft 4 with a cross section enlarged section 4 "provided, the outer cross section of the cross-sectional shape is adapted to the opening 10, i.e. also in the illustrated embodiment forms a hexagonal cross-section, so that when the Crown body 3 relative to the actuating shaft 4, the section 4 ′′ engages with the opening 10 comes and thereby a drive connection between the crown body 3 and the control shaft 4 is made.
  • a flange-like annular section follows 4 "', whose outer diameter is equal to the diameter of the recess 16 and which forms the end of the actuating shaft 4 facing the end face 14.
  • the control shaft 4 also has a bore 18 which is coaxial with the longitudinal axis L arranged and to the section 4 "'having the end of this actuating shaft is open.
  • the bore 18 serves to partially accommodate the compression spring 5 and forms a second support surface for this spring at its closed end.
  • the opening 10 and the section 4 " are on Transition to section 4 'in each case at 19 and 20 conical or frustoconical beveled so that interference-free engagement of the section 4 "or of this Section formed hexagon in the opening 10 or in the opening of this formed hexagon is guaranteed.
