  • a screwed crown having the necessary seal for a diving watch can be made available, which, moreover, allows to include in the crown functions other than those commonly provided on this kind of watch crowns. .
  • it can be avoided unnecessary drilling the watch case thus improving the sealing of the timepiece.
  • the production of the corresponding watches and their service is greatly facilitated.
  • an embodiment of the present invention provides that the prestressing spring is housed in the inner part of said hollow space and exerts a prestressing force on said auxiliary head oriented towards the inside of the timepiece, so that the auxiliary head is, in normal position, pressed against said partition wall and serves, in case of overpressure inside the timepiece, valve.
  • this embodiment makes it possible to include the function of a pressure relief valve in a screw crown for a diving watch.
  • the prestressing spring is housed in the outer part of said hollow space and exerts a prestressing force on the auxiliary head oriented towards the outside of the timepiece, so that the head auxiliary is prestressed to the outside and can be used as a push-button.
  • the screw crown shown in figure 1 is provided for the timepieces, as in particular for diving watches and comprises a cylindrical head 2 secured to a central rod 3 housed so as to be able to translate along its longitudinal axis and a rotation around this axis in a fixed tube 1.
  • Said cylindrical head 2 is provided on its inner circumference with a threaded portion 2.1 adapted to be screwed onto a thread 1.1 on the outer circumference of the fixed tube 1 to ensure complete sealing when the ring is in the position screwed on the watch.
  • a wreath for diving watch comprises in particular a cylindrical head 2 which comprises a hollow space inside separated by a wall of limitation 2.2 in two parts.
  • a first inner portion 2.3 is oriented towards the inside of the timepiece and an outer portion 2.4 is oriented outwards and houses an auxiliary head 4 secured to an auxiliary rod 5 which passes through at least one opening 2.2. 1 said limiting wall 2.2.
  • the auxiliary head 4 can be fixed on the auxiliary rod 5 for example by clipping, by screwing, or can be driven there.
  • the auxiliary rod 5 is housed in the fixed tube 1 in a sliding and rotatable manner and at least partially surrounds the central rod 3 which, in turn, is slidably housed in the auxiliary rod 5.
  • a prestressing spring 6 is arranged in said hollow space of the cylindrical head 2 so as to effect a prestressing force on said auxiliary head 4.
  • the control device according to the present invention then has, in the form of the auxiliary head 4, additional means to which another function of the crown can be attributed.
  • this function consists of a built-in pressure relief valve.
  • said preload spring 6 is housed in the inner portion 2.3 of said hollow space of the cylindrical head 2, between the inner side of the partition wall 2.2 and a bearing surface 5.1 arranged on the inner end of the auxiliary rod 5.
  • the spring 6 exerts a prestressing force on the auxiliary head 4 which is oriented towards the inside of the timepiece.
  • the auxiliary head 4 is, in normal position, pressed against said partition wall 2.2 and ensures the sealing of the device respectively of the whole diving watch.
  • the auxiliary head 5 serves as a valve.
  • FIG. 2a illustrates the ring screw in its screwed position ensuring the maximum tightness of the timepiece.
  • the cylindrical head 2, the auxiliary head 4, and the parts integral with these parts are displaced towards the outside of the watch by a distance C 1 corresponding to the unscrewing stroke.
  • the Figure 2c finally shows the position taken from the screw-type crown, in which the cylindrical head 2 and the auxiliary head 4 are still displaced outwards by an additional distance C 2 corresponding to the pulling race of the crown.
  • This series of figures corresponds to the conventional operation of a screw-type crown and does not require any additional comments.
  • the figure 2d illustrates, in turn, the screw-in crown according to the figure 1 in the screwed position, the forces exerted by the pressure outside, respectively inside the watch, are symbolically indicated by arrows.
  • the auxiliary head 4 is in its normal position, preloaded by the spring 6 against the partition wall 2.2 of the head cylindrical 2, it ensures the sealing of the device. It is detached from the cylindrical head 2 from a predefined value of the pressure inside the watch exceeding the pressure outside by a given value.
  • the valve integrated in the screw crown opens and rebalances the pressures inside and outside the watch, thus avoiding an explosion of the watch.
  • the prestressing spring 6 can be dimensioned so that the amount of excess pressure inside the timepiece which triggers the opening of the valve is in the range of about 1 bar to 2 bars. It can in particular be chosen so that the rebalancing of the pressures takes place at a value of the overpressure of about 1.5 bar.
  • auxiliary rod 5 is attached to the auxiliary head 4 by two symmetrical and opposite arms which pass through two corresponding openings 2.2.1 said limiting wall 2.2 and partially embrace the central rod 3.
  • the screw ring according to the present invention normally comprises a clutch as known in the prior art for performing with the cylindrical head 2 the usual functions of such a ring.
