FLUID-TIGHT WATCH PROVIDED WITH AN AUTOMATIC WINDING-UP SYSTEM AND KEY SETTING STEM Filed Sept. 2. 1955 IIIIIIIII/I/IIIIIIII United States Patent Ervin Piquerez, Bassecourt, Switzerland Application Septemberi, 1955, Serial No. 532,216
Claims priority, application Switzerland September 8, 1954.
10' Claims. or. 58-90 My invention has for its objects a fluid-tight watch provided with an automatic winding-up system. According to my invention, the stern controlling the watch clockwork is fitted inside an inner section of the case and terminates ,at least approximately, in register with the outer surface of the said section of the case, the said stem being, furthermore, deprived of any control knob and being concealed by an outer section of the case fitted over the inner section enclosing the said stem.
I have illustrated byway of examplein the accompanying drawing three preferred embodiments of my invention. In said drawings: g i
Fig. 1 is a partial axial cross-section of the first embodiment; ,7
Figs. 2,3 and 4 show detail modifications;
Figs. and 6 are partialaxial cross-sections of each of the two other embodiments. I
The embodiment illustrated in Fig; l is constituted by a wristwatch including a case formed by a bottoin and an upstanding peripheral flange,a separate rim 2, a glass 3 and an outer ring 4 carrying the lugs 5 for the wrist band; across the latter are secured bars 6 adapted to carry the ends of the wrist band 7 provided with the usual buckle and tongue. Inside the case is fittedthe mechanisrn 8 of the watch, associated with an automatic winding-up system The stem 9 passing through the upstanding flange on the bottom 1 is intended either solely for setting the time or else, both for time-setting and for winding-up the watch by hand Whenever the automatic winding system is not operative, for any reason whatever. I
It is assumed that the mechanism 8 is a high. grade clockwork and that it issufficient to reset it only at long intervals. 'Withthis assumption, the time-settingstem 9 is not provided with the usual knob. and it ends substantially flush with the outer surface of the upstanding flange 1 While it is entirely concealed from view by the case band or peripheral Wall 4 of the case, which case band must be removed to allow reaching the said stem 9. The outer end of the said stem is provided with an axial square opening It) into which may be fitted the end of a tool for rotating the said stem; when the stem is to serve for Winding-up by hand, it may be drawn outwardly into the desired winding-up position by engaging ones finger nail underneath the small flange 10a provided at the end of the said stern and housed with some clearance inside a correspondingly shaped housing 10!) formed in the upstanding flange. 11 designates a packing rigid with the case band and forms a joint with the upstanding flange so as to prevent moisture from entering the ciockworl; over the surface of the time-setting stem.
When it is desired to actuate the stem 9, it may be accomplished by resorting to a tool fitted inside the actual watch. To this end, there is shown in a modification illustrated in Fig. 2 an axial housing in the cross-member 12, closing the buckle 14 to which asection of the wrist band is attached; inside the said housing is concealed the tool 15.
As illustrated in Fig. 3, it is also possible to provide ice 2 such an axial housing inside the bar 16 connecting the lugs on the side of the case.
- Lastly, as illustrated in Fig. 4, it is possible to give the free end of the tongue 17 in the wrist band the shape of a tool for the purpose specified.
The embodiments illustrated in Figs. 5 and 6 differ from those illustrated in Fig. 1 only by detail features. In the said figures, the winding-up stem is assumed to be made of synthetic plastic material, for instance of a material of the polyamidic type, such as that sold under the registered trade name nylon. I
It is likewise possible to resort to a vinylic'resin, to polystyrol, to the material sold under the trade name lexiglas or to any other non-metallic compressible material. By reason of the presence of such a substance, the stem forms a fluid-tight joint with the upstanding flange without any further member being inserted therebetween. The stem may also be made of metal.
In Fig. 5, a very small opening 2i) formed in the case band 4 allows turning the stem 18 without removing the said peripheral case band. i
In Fig. 6, the outer end of the stem 18 is covered both by the depending edge of the glass 13 and by the case band. It will be remarked that the case is then provided with a single joint between the bottom of the case and the lower edge of the glass, the case band 4 exerting a pressure on the glass along the said edge.
