Watch, in particular wrist watch

#This application is the National Stage of PC/AT2015/050088 filed on Apr. 2, 2015, which claims priority under 35 U.S.C. §119 of Austrian Application No. A50257/2014 filed on Apr. 7, 2014, the disclosure of which is incorporated by reference. The international application under PCT article 21(2) was not published in English.

#The invention relates to a watch, in particular a wrist watch, having a housing, having a dial arranged in the housing, having at least one endless conveyor, which is guided around two deflection guides having deflection axes parallel to the dial, for at least one hand, and having a drive for the endless conveyor.

#In watches, the hands of which are moved along a linear timescale (DE 202 06 965 U1), providing an endless conveyor guided around deflection wheels in the form of a toothed belt drive and arranging the dial laterally adjacent to the upper toothed belt side is known, so that the hands connected to the toothed belt drive overlap the dial having the timescale. To take into consideration the uneven movement of the hands in the deflection region of the toothed belt in a projection on the dial, the hands are concealed in the deflection region of the toothed belt, which requires a circumferential length of the toothed belt, which carries three hands arranged at equal distance to one another, three times the dial length, so that upon one hand leaving the dial, another hand enters the region of the dial and thus a continuous time display is ensured. These known watches have the disadvantage, however, of the required excess length of the toothed belt, the space requirement of which opposes the use of such watches as wrist watches.

#The subject matter of the invention is shown by way of example in the drawing. In the figures

#FIG. 1 shows a watch according to the invention in a housing section in parallel to the dial,

#FIG. 2 shows a section along line II-II of FIG. 1,

#The watches according to the exemplary embodiments each have a housing 1, which is only shown schematically, having a viewing window 2, which exposes the view of a dial 3, which is arranged above a watch mechanism 4. With the aid of this watch mechanism 4, at least one hand 5 is moved along a linear timescale 6, which is provided on the dial 3, and this is done with the aid of an endless conveyor 8 guided around deflection guides 7.

#According to the exemplary embodiment according to FIGS. 1 to 3, the endless conveyor 8 is constructed from two traction mechanisms 10, which are arranged in parallel and are guided endlessly around deflection rollers 9, and which accommodate two hands 5 in a spacing corresponding to half the circumferential length of the endless traction mechanisms 10. Because the dial 3 according to FIGS. 2 and 3 extends between the two sides of the endlessly guided traction mechanisms 10 and is located in the shared axial plane of the deflection rollers 9, the dial 3, the length of which corresponds to the vertex spacing of the deflection guides 7, conceals in each case the hands 5 moved on the lower side, so that with the exception of the hands 5 opposite to one another in the vertex regions of the deflection guides 7 of the endless conveyor 8, only one of the two hands 5 is visible at a time and enables the reading of the time units along the timescale 6. If the visible hand 5 is moved at the end of the timescale 6 via the deflection guides 7 from the upper side to the lower side of the dial 3, the opposing hand 5 thus appears in the visible dial region, which makes continuous time telling possible. To be able to differentiate the two time sections displayed by the two hands 5 from one another, the two hands 5 can be designed differently, for example, can have different colors or shapes.

#Because of the fact that the hand path encloses the dial 3 in length, the dial 3 has to be fastened to a mount 11 outside the region of the hand path. This mount 11 is indicated in the exemplary embodiment by a housing shoulder 11, on which the dial 3 is supported with fastening sections 12 extending between the sides of the endlessly guided traction mechanism 10 in relation to the housing 1.
