FIELD OF THE INVENTION The present invention relates to a watch comprising a case and a movement fitted with at least one control organ that is accessible from outside the movement and intended for activating at least one function.
DESCRIPTION OF THE RELATED ART Watches of this type are known, and for instance offer the functions of start and stop and of zero reset of a chronograph watch. These watches generally have push-pieces protruding from the side of the watchcase, generally at the two o'clock position and at the four o'clock position.
These push-pieces make the watch generally bulkier and have the drawback of being elements that may get caught. They are not very comfortable to manipulate, above all for users wearing gloves. Their protruding shape may make the watch unpleasant to wear and produce a massive, not very aesthetic look. In addition, it is difficult to guarantee their protection against the entry of water and dirt, particularly when manipulating the push-pieces in a humid or polluting atmosphere.
SUMMARY OF THE INVENTION It is the aim of the invention to remedy these drawbacks and create a watch without visible external push-pieces in which the functions integrated into the movement, such as the chronograph functions, may be activated very easily even while wearing gloves, and in which the function controls work in a well defined, highly precise manner while having a solid construction and long life. To that end, the watch according to the invention comprises a watch comprising a case having a fixed part and a mobile part. The mobile part is tiltably mounted onto the fixed part about a first pivot and a second pivot. The first and second pivots define a swivel axis of the mobile part and are located at two diametrically opposite positions with respect to the face of the watch (for example at 3 o'clock and 9 o'clock). The case houses a watch movement that comprises at least one control organ for mechanically activating a function of the watch. The watch further comprises an actuating mechanism coupled to the mobile part and operable to actuate the control organ in response to a tilting motion of the mobile part relative to the fixed part about said swivel axis.
In accordance with the invention external push-pieces are not used, and activation of the controls of functions of the movement is facilitated even when wearing gloves. The watch has a construction that is very solid and durable, and functions precisely owing to a tilting motion about a given swivel axis while conferring great wearing comfort und an aesthetic look.
Preferably, the movement comprises first and second control organs for activating a first function and a second function respectively. In this case the first control organ is actuated in response to a tilting motion of the mobile part relative to the fixed part in a first direction and the second control organ being actuated in response to a tilting motion of the mobile part relative to the fixed part in a second direction opposite to the first direction. As such, the watch may comprise a chronograph mechanism, with the first and second functions being respectively a start/stop function and a zero-reset function of said chronograph mechanism. These characteristics yield a very precise control of at least two function controls, particularly the functions of a chronograph watch.
Other advantages will become apparent from the characteristics expressed in the dependent claims and from the description setting forth hereinafter the invention in greater detail with the aid of drawings representing schematically and in exemplary fashion an embodiment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment illustrated in the figures consists of a chronograph-type watch. This chronograph 8 comprises a watchcase 9 including a fixed part 10 and a mobile part 11 mounted so as to swivel about the fixed part 10. Referring to FIG. 2, said fixed part consists of a frame 12 and two horn segments 14, 15 attached to frame 12 by screws 16 so as to form a bracket 20 intended to hold the mobile part 11.
This mobile part 11 comprises a middle 21 sealed off below by a screwed bottom 22 with gasket 19.
The following elements are mounted into the middle, and can be seen in FIG. 2 from bottom to top: a movement 23, a dial 24, indicating organs 25, an inner bezel 26 screwed onto the middle, a collar 27 made of plastic, a sealing gasket 28 for the crystal, and a crystal 29, as well as a crown 33 of customary design.
The middle 21 is pivotably or tiltably mounted onto the bracket 20 through two screws 30 intended to cooperate with two pivot segments 31 provided on frame 12 in the 3 o'clock position and the 9 o'clock position. By pressing the upper side of the mobile part 11 at the 12 o'clock position or at the 6 o'clock position one obtains a tilting motion of the mobile part 11 relative to the fixed part 10 following a swivel axis 32 defined by the central axis of the two screws 30 and of the two pivot segments 31.
The movement 23 comprises two control organs 40,41 (FIG. 4) accessible from outside the movement, and intended to activate at least two functions, here the, functions of start/stop and of zero reset of the chronograph. As best seen in FIG. 4A, these control organs comprise stems extending outwardly from the movement that are arranged in conventional manner at the 2 o'clock position and at the 4 o'clock position.
For an activation of these two functions, the watch is provided with two identical actuating mechanisms 44, 45 cooperating with the fixed and mobile parts 10, 11 in order to transform the tilting motion of the mobile part 11 into an action upon either of the control organs 40, 41.
The two actuating mechanisms 44, 45 are mounted into the middle 21, each comprising a piston 46 (FIGS. 3A, 3B) mounted slidingly and sealingly into the middle 21 and provided with a spring 47 and a sealing gasket 48. The lower end of piston 46 cooperates with a recess 49 provided in the bracket 20, while the head of piston 46 is in contact with a first intermediate wheel 50 mounted rotatably about a screw 51 set horizontally into the middle 21.
This first intermediate wheel 50 acts upon a second intermediate wheel 52 mounted via a ball bearing on a vertical arbor 53 of the middle (FIG. 4A). The second intermediate wheel 52 drives a lever 54 mounted via a ball beating on a vertical arbor 55 of the middle. The curved end 56 of lever 54 is intended to activate control organ 40 or 41 of the movement 23. The two actuating mechanisms 44,45 have an identical design that is symmetric relative to a plane of symmetry passing through the 3 o'clock position and the 9 o'clock position, one 44 actuating the control 40 of start/stop, the other 45 actuating the control 41 of zero reset of the chronograph.
The tilting motion of the mobile part 11 in the two opposite directions is limited by two adjustable stops 60 screwed into the bracket 20 at the 6 o'clock position and at the 12 o'clock position (FIG. 5).
The middle 21 is provided with two poising buttons 62 (FIGS. 2 and 6) mounted next to the two pistons 46, and intended to cooperate elastically with recesses 63 provided in bracket 20, in order to stabilise and poise the mobile part 11 in its tilting motion.
The watch moreover comprises a selection mechanism 66 (FIGS. 2 and 7) mounted onto the middle 21 and including a cursor 67 intended to be actuated by the user, and a slide 68 screwed onto the cursor.
The bottom face of slide 68 has a recess 69, and is intended to cooperate with three pins 70, 71, 72 driven into bores of bracket 20 in order to realise a selection of the movements of mobile part (II).
In the middle position illustrated in FIG. 7 none of the pins is in contact with slide 68, hence the mobile part 11 may be swiveled in the two directions in order to control the two chronograph functions of start/stop and zero reset.
With the cursor 67 pushed to the right in FIG. 7, pin 72 on the right is in contact with slide 68, hence the mobile part 11 may only perform a tilting motion counterclockwise about the swivel axis 32. A motion clockwise is inhibited. In this position a control of the start/stop function is possible while control of the zero-reset function is inhibited.
With the curser 67 placed to the left in FIG. 7, pins 70 and 71 are in contact with slide 68, and the mobile part 11 cannot be tilted, hence no control function of the chronograph can be effected.
FIG. 7 in addition shows the entire set of parts of the bracket 20 including the two horn segments 14, 15 screwed into the frame 12 with screws 16. The facing sides 75, 76 of the bracket 20 and mobile part 11 are machined so as to form cylindrical surfaces with a spherical base and very narrow gap allowing a sliding motion of one relative to the other during the tilting motion about the swivel axis 32, the latter constituting the central axis of the cylindrical surfaces.
Referring to FIGS. 8A, 8B and 8C, this tilting motion is barely visible owing to the very narrow gap between the fixed and mobile parts 10, 11.
The control positions of the start/stop function (FIG. 8B) by pressing at the 12 o'clock position and of the zero-reset function (FIG. 8C) by pressing at the 6 o'clock position are barely distinguishable from the intermediate rest position of the mobile part 11 (FIG. 8A). Through this mechanism of tilting about a well-defined swivel axis 32, one obtains a precise working and a very easy control of the functions even when wearing gloves, while awkward and bulky push-pieces are avoided.
FIGS. 3C and 7 show that the bottom face of the bracket that is facing the wrist of the user exhibits a concave central segment 80 securing elevated wearing comfort. This central segment is surrounded by a peripheral flat segment 81 yielding a stable position of the watch when placed onto a flat support.
It is understood that the embodiment described hereinabove is not of a restricting character, and may receive any modification desired within the scope defined by the claims. In particular, the control functions of the movement may be of any other type, such as those of a repeater, a watch with striking work, a split timer, a timer, a watch with two or more time zones etc. The bracket and the mobile part may be of any other design.
The watch could also exhibit a double bracket with crossed swivel axes enabling a tilting motion about two perpendicular swivel axes. The actuating mechanisms and the selection means could have any other design.
