Definitions

  • the parts of the frame are adapted to a case of particular dimensions.
  • the case is not interchangeable.
  • the parts of the frame surround the case in such a manner that the outer dimensions of the watch are increased, but this greater bulk is not accompanied by any market advantage;
  • the chief object of the invention is to provide a wristwatch that can be easily changed in appearance, the watch being composed of various outer parts that are simple in shape, interchangeable, and easily and quickly adapted to each other.
  • Another object of the invention is to provide a watch of interchangeable parts, of which certain visible parts can be made of some material other than metal, notably of a material that cannot be machined as metal, such as synthetic precious stone, or of which these visible parts can be covered with a material, such as cloth.
  • FIG. 1 is a top view of a first embodiment of the invention
  • FIGS. 2, 3, and 4 are top views of three modifications using some of the parts of the watch shown in FIG. 1;
  • FIG. 5 is an enlarged view partly in cross section, taken along a plane passing through the axis of the watch shown in FIG. 1;
  • FIGS. 8 and 9 are views corresponding to that of FIG. 7 of two other embodiments of the invention.
  • FIG. 12 is a top view, partly cut away, of the last embodiment.
  • FIG. 13 is a partial axial section, on expanded scale, taken along line XIII-XIII ofFlG. 12.
  • the wristwatch illustrated is composed of .two major parts: a case 1 and a mount comprised of two arcuate bars 2 and 3 arranged longitudinally and connected together by screws 4 and 5
  • the details of the case construction are shown in FIG. 5.
  • the case is composed of a round cap, or calotte, 6, constituting both the back and the middle of the watchcase and of a watchglass, or crystal, 7, pressing on a gasket 8 held in an annular recess incorporated in the upper edge of the sidewall of the cap 6.
  • the edge of the watchglass is held in place by the upper part of the sidewall of this recess.
  • the watchglass is held to the cap 6 by reducing the pressure within the case I, as will be explained.
  • the case I holds a movement 9 of conventional construction, such as a round mechanical movement of which the plate edge rests on a shoulder 10 of the cap sidewall.
  • Two hands 12 and 13 move above the dial 11.
  • a ring 14 holds the movement 9 within the case I.
  • the movement is automatically kept wound by an oscillating weight, and comprises a winding but-' ton, or winding crown 15, located outside of the cap 6 at the end of a pipe (not shown) provided with a watertight seal.
  • the watchglass 7 is held to the case by putting the space holding the movement under vacuum, causing the watchglass to be pressed against the gasket 8.
  • the bars 2 and 3 have a generally U- shaped section, the opening, or hollow, of the U facing the case 1.
  • Each leg of the section embodies at its end a bevelled edge that extends the entire length of the bar.
  • the upper bevelled edge presses against the slanting edge of the watchglass 7, and the lower bevelled edge presses against the slanting outer side face 16 (defining a truncated cone) of the cap 6.
  • the inner face of the bar 3 embodies a recess 17 accommodating the winding crown 15.
  • the recess can be square, cylindrical, or any other suitable shape whatever. The presence of this recess causes each leg of the bar 3 to press at two points against the watchglass 7 or the cap 6, as the case may be. Since the bar 2 has no recess corresponding to the recess 17, its two legs press at a single point, or over a single area, the one leg against the glass 7 and the other against the cap side face 16.
  • Each of the screws 4 and 5 connecting together the bars 2 and 3 carries at one end a knurled head that is sufficiently high to cause it to project outside of the bars 2 and 3.
  • the head end of the screw shank passes freely through an opening in the neighboring bar, whereas the other end of the same screw is turned into a threaded hole in the other bar.
  • FIG. I comprises a simple round case, not connected to a wristlet, and a rigid frame, constituted by the bars 2 and 3 and the screws 4 and 5.
  • the embodiment is easily taken apart, since it is only necessary to unscrew the screws 4 and 5 in order to remove the case 1.
  • the appearance of the watch can also be changed by shifting the position of the same case.
  • FIG. 3 in which the appearance of the watch is modified by turning the case through 90 to occupy a transverse position between the bars 2 and 3. Since the bars 2 and 3 are now spaced farther apart than is the case with the watches illustrated in FIGS. 1 and 2, the transverse screws 20 and 21 are necessarily longer than the screws 4 and 5.
  • the screws 4 and S can be replaced by elements (not shown) consisting each of several parts, enabling the elements to be lengthened sufficiently to be used with the watch illustrated in FlG. l or with that illustrated in FIG. 3.
  • the bars 2 and 3 instead of each having a threaded hole for a screw, can carry threaded tubes slightly shorter than the width of the wristlet 18, thereby increasing the extent to which the bars 2 and 3 can be spaced apart with screws of the same length.
  • FIG. 4 shows a modification in which the bars 22 and 23 have the same dimensions and shape as do the bars 2 and 3, but each incorporates at one end a respective recess 24 and 25 in which are countersunk the heads of the screws 26.
  • the mount shown in FIG. 4 is in other respects exactly the same as that shown in FIGS. 1 to 3; but the case 27 is square with slightly bowed sides, the construction of the case corresponding to that shown in FIG. 5.
  • the curves of the sides of the monocoque, or shell, case 27 being the same as those of the bars 22 and 23, the edges of the watchglass and the side faces of the case 27 contact along their entire length the bevelled edges of the bars 22 and 23.
  • the bars 2 and 3 can be replaced by bars that are straight, narrower, or wider.
  • FIG. 6 illustrates another way of altering the appearance of the watch described.
  • the bar 2, shown in cross section, is covered by an interchangeable sleeve 28 made of cloth, leather, or of a synthetic plastic, the two longitudinal edges of the sleeve being turned down against the inner face of the bar so as to be clamped against the side faces of the case 1.
  • the bars 2 and 3 have a sectional profile that will hold the watchglass against the case, which, instead, can be kept closed by conventional means, as is the case 29 in FIG. 7.
  • This modification permits an elastic suspension of the case between the two bars 30, by incorporating between each bar 30 and the case 29 a rubber lining 31 constituting a shock absorber.
  • the embodiments described thus far are particularly suited to metal mounts.
  • the bars 2 and 3 can be made from sectional bar stock-of nickel-silver or stainless steel, for examplewhich is then finished to the desired shape. In this case, it is not difficult to cut the threads for the transverse screws. Where the bars are metallic it is easy to provide a connection between these screws and the bars at the height of the screwheads, as seen in FIGS. 10 and 11. To this end, there is cut in the lower part of the bar a slot 35, of which the width is approximately equal to the diameter of the screw shank, and in the outer face a shallow circular recess 36, with a flat bottom, for holding the screwhead.
  • the construction described also permits the bars to be made of materials other than easily machined metals. Any material having an acceptable appearance can be used.
  • the bars 2 and 3 can be made, for example, of a mineral, such as glass or sapphire, of wood, of a synthetic material, such as sintered ceramic, or of a thermosetting synthetic plastic.
  • a threaded sleeve can be countersunk in a slightly conical hole of the bar, as is the threaded sleeve 37 in the bar 38 shown in FIG. 12.
  • FIGS. 12 and 13 show a last embodiment of the invention.
  • the mount consists of two straight bars 38 and 39 that are held together by screws 40 and 41 with countersunk heads.
  • the case 42 which is shown in cross section in FIG. 13, is clamped within the mount and comprises a round cap 43 holding the movement 44, and a watchglass 45 having a peripheral cone-shaped wall 46 of which the lower edge presses on a watertight gasket 47.
  • the means for fixing the movement within the cap 43 are not shown.
  • the movement does not have a minute hand.
  • Mounted on the pipe 48 of the hour wheel is a disc-shaped dial 49 positioned just below the watchglass 45 and comprising a peripheral wall 50 in the shape of a truncated cone and marked with the hours.
  • the dial 49 makes a 'complete turn once every 12 hours, each point of its periphery successively passing underneath a magnifying glass 51 shaped like a bar and mounted crosswise between the bars 38 and 39.
  • the magnifying glass has a flat inner surface which is tangent to the truncated-cone wall 46 of the watchglass.
  • the magnifying glass incorporates a hair 52 positioned radically along the generant of the tangent between this glass and the watchglass. Since only that part of the dial 49 visible below the magnifying glass 51 is used to show the time, the rest of the watchglass can be given any suitable ornamentation. Owing to the magnification of the glass 51 and to the marking of the hours on the dial periphery, which is nearly equal in size to the circle of maximum diameter of the case 42, the time can be read with sufficient accuracy. It has been shown that it is possible to read the time to within nearly one minute on a dial 49 of about 20 mm. diameter.
  • a movement having a dial turning every l2 hours in a case of the kind described has the following advantage: to set the time of a watch thus designed it is only necessary to loosen the screws 40 and 41 slightly in order to turn the case 42 about its axis until the correct time appears under the hair 52. Since the movement 44 can be self-wound by an oscillating weight, the case does not require a winding button, enabling the movement to be completely and permanently sealed.
  • the bars 38 and 39 for clamping the case 42 each embody a concave recess shaped to fit the case.
  • the bars also have two diametrically opposed recesses 53 and 54 located next to the recesses for the countersunk heads of the screws 40 and 41.
  • the inside faces of the bars 38 and 39 each incorporate a shallow recess (not shown) that receives a respective pin 55 embodied by each end of the glass 51, for holding the glass in place. Consequently, when the screws 40 and 41 are tightened, the case 42 and the glass 51 are simultaneously clamped between the bars 38 and 39.
  • the case 42 and glass 51 can be removed simply by loosening the screws.
  • the case can be replaced by a round watch of the same dimensions, such as a pocket watch or even a pendant watch having on one side a winding crown and, on the other side, a ring for hanging the watch, the crown and ring being contained within the recesses 53 and 54.
  • a wristwatch comprising a frame having a plurality of mutually adjustable parts, a wristlet connected at its two ends to said frame, and an interchangeable case holding a move ment and removably held within, and by, said frame, said wristwatch further including two spaced longitudinal bars comprised by said frame, each said bar having an inner face that faces said case, and means incorporated by each said bar inner face for holding said case between said bars, two crossmembers comprised by said frame, and means for fixing said bars to said crossmembers and for adjusting the spacing between said bars is dependence on the dimensions of said case.
  • each said bar is arcuate.
