Definitions

• the present invention relates to a watch comprising a case provided with a rotating bezel, an annular part of which is toothed, a winding stem having a section of polygonal section located outside the movement of the watch, a pinion provided with an opening of complementary section to that of said section, engaged thereon, the toothing of the pinion being engaged with that of said annular toothed part, forming a kinematic connection between the rotating bezel and the winding stem .
• the object of the present invention is to remedy, at least in part, the abovementioned drawbacks and to ensure that the winding of the watch which has been perceived hitherto as a negative operation, and which has been eliminated in automatic and electric watches, it becomes something pleasant and fun and which, unlike a watch wound by the winding stem, is more easily wound by keeping it on the wrist.
• arrangements have been made to protect it from dust and to ensure a long service life of the rotating bezel and protective seals.
• the subject of this invention is a watch of the aforementioned type, characterized in that said pinion is positioned axially between two abutments integral with the case, said polygonal section of the winding stem having a length chosen to allow movement axially said winding rod between at least two positions, one for winding and the other for setting the time, while maintaining the kinematic connection between the bezel and the winding rod via said pinion.
• the normal spring of a manual winding watch is replaced by a sliding strap spring such as those used in watches with automatic winding.
• the rotating bezel allows to exert on the spring a torque significantly higher than that exerted via the winding stem. Therefore, it is extremely advantageous that once the mainspring is fully cocked, it can slide into the barrel, so that the bezel can be continued indefinitely, although the spring is fully cocked, without risk of damage. spring.
• the user does not know if the spring is armed or not. It may therefore be advantageous to add an indicator of the degree of arming of the mainspring, which is a device known per se.
• the watch according to the invention does not require any modification as regards the actual movement, the only modification necessary is that of the re ⁇ mount rod. It is therefore possible, thanks to the present invention, to adapt the winding system to any watch by only changing the winding stem.
• Figure 1 is a partial view in axial section of this watch.
• Figure 2 is an enlarged view of a detail of Figure 1.
• the watch illustrated by this figure comprises a movement 1 covered with an indicator dial 2, housed in a case comprising a middle part 3, a base 4 and a crystal 5.
• the upper part of the middle part 3 has an annular recess 6 in the bottom of which is formed an annular groove 7.
• a rotating bezel 8 is arranged in the annular recess 6 and is held axially by pins 9a formed in the extension of the ex ⁇ screw end 9, passing radially through the rotating bezel 8 and distributed angularly around it. These pins 9a are engaged in an annular groove 10 on the side face of the annular recess 6.
• An annular groove 11 parallel to the annular groove 10 serves to receive a 0-ring seal 12.
• a second seal 13 is housed in a groove ⁇ annular re 23, formed in the underside of the rotating lu ⁇ net 8.
• this seal 13 has a semi-circular section, its flat face being glued in the bottom of the groove 23.
• the shape of the seal 13 and the bonding thereof make it possible to increase its service life and facilitate rotation of the rotating bezel 8 in both directions.
• the seal 12, meanwhile, is preferably an O-ring seal.
• the underside of this rotating bezel 8 also has a projecting annular portion 8a at the end of which an edge toothing 8b is provided, this annular portion 8a being housed in the annular groove 7.
• This groove 7 communicates with a cylindrical housing 14, whose axis of revolution coincides with the axis of the winding rod 15.
• This winding rod 15 comprises a section of square section 15a which passes through an opening of the same section, centered on the axis of a pinion 16 meshing with the teeth 8b.
• a closing member 17, carrying a tube 18 provided with a 0-ring seal 19 intended to cooperate with a winding crown 20 is fitted into the cylindrical housing 14 by two screws (not shown), fixed in the middle part 3 on either side of the winding stem 15.
• the pinion 16 is fixed axially between two bu ⁇ tees constituted by the bottom of the cylindrical housing 14 on the one hand, and the internal face of the member closure 17.
• the lateral face of the latter has a groove 17a in which is housed a 0-ring seal 24.
• Spacers 21, 22, for example made of nylon, can be placed on either side of this pinion 16 to avoid seizing. Thanks to this arrangement, the square section 15a of the winding stem 15 can slide freely through the opening of the pinion 16 and the latter remains in engagement with the teeth 8b of the rotating bezel. As a result, the winding stem 15 can occupy different positions, two or three for winding, setting the time, even setting the date, like a normal winding stem, the kinematic link remaining constantly established between the rotating bezel 8 and the winding stem 15, via the pinion 16 integral in rotation with this stem 15 by virtue of the section 15a of square section.
• winding and time-setting mechanism is fully protected against water and dust infiltration by gaskets, thus protecting this mechanism from deterioration or seizure of the moving parts rotating bezel 8 and pinion 16.
• the casing of the watch is only slightly modified compared to a normal case.
