Definitions

  • An object of the present invention is to provide an inexpensive watch which is completely waterproof, and indicates the approximate time.
  • An object of the present invention is to provide a watch having no element traversing the watch case, and having only one hand and a bezel surrounding the watch case and presenting graduations, the watch case being mounted rotatively in said bezel.
  • a particular embodiment of the invention is characterized in that the hand rotates once in three hours time.
  • FIG. 1 shows a partial sectional view across a watch according to the invention
  • FIG. 2 is a perspective view of the bezel of the watch shown in FIG. 1;
  • FIG. 3 illustrates the time setting of a watch according to the invention
  • FIG. 4 is a perspective view of the waterproof watch case.
  • FIG. 5 is a perspective view of the described embodiment of the invention.
  • a symbollically represented watch movement 1 is inserted in a watch case 2 comprising an upper transparent part 3 and a watch case back 4.
  • the watch movement 1 is a movement which does not need any manual winding operation and may be an automatic watch movement or an electrical movement.
  • the parts 3 and 4 forming the watch case 2 are connected together in an absolutely waterproof manner at the facing of the two rims 5 and 6. Due to the fact that no element, such as a winding stem, traverses the watch case 2, the two parts 3 and 4 can easily be put together in a perfectly waterproof way.
  • the dial carries no indications or graduations and can therefore be mounted in any angular position.
  • the watch case 2 is frictionally mounted in a bezel 9 surrounding the watch case 2 near the rims 5 and 6.
  • the bezel includes a ring 10 having openings 17, 18 and 19 therein as well as certain graduations thereon.
  • a rotative disc 11 showing the indications of the full hours, and possibly other indications, is located inside the bezel 9.
  • Disc 11 is limited in rotation by a pin 15 penetrating into a groove of the disc 11.
  • the angular limitation of the disc 11 is such that hour indications 16 expected to appear in the window 17, for instance, can not appear in one of the other windows 18 or 19 and vice vers
  • the waterproof watch case shown in FIG. 4 can easily be introduced from below into the bezel shown in FIG. 2. Once inserted, the case is frictionally held in the bezel and can be rotated therein by hand in the manner shown in FIG. 3. Because of the construction of the ring 10 of the bezel 9, a watch case including a movement and a hand can be inserted in different bezels and bracelets by the user.
  • the invention provides a watch having no winding stem, since the time setting of the watch according to the invention is not made in the usual manner by rotating the hand 7 relative to the movement 1. Instead, the whole watch movement and its case are rotated relative to the bezel.
  • the ring 10 of the bezel 9 is divided in a manner to indicate at three positions located at an angle of one to the other the full hours indications. Every 120 portion itself is divided into four parts by lines 21 corresponding to the quarters of an hour. Lines 22 divide the quarter of an hour sections into intervals corresponding to five minutes (FIG. 5).
  • the whole movement that is, the unity of the watch case 2
  • the bezel 9 is rotated relative to the bezel 9 in the manner shown in FIG. 3 to bring the unique hand 7 in front of the division of the ring 10 of the bezel 9 corresponding to the time to be indicated.
  • the hand 7 can easily be positioned with sufficient accuracy to indicate the minute.
  • the disc 11 can be rotated by hand from one to another position so that in the three windows 17, 18 and 19 the following numerals will be displayed: in the window 17, one of thenumerals 1, 4, 7 or 10; in the window 18, one of the numerals 2, 5, 8 or 11; and in the window 19, one of the numerals 3, 6, 9 or 12.
  • the most probable hour indicating numeral 16 (FIG. 5) is displayed in the closest window to the hand.
  • the latter presents a fifth position in which no numerals at all appear in the three windows. This is the position in which the disc 11 will mostly be as soon as the user of the watch knows which numerals can appear in the respective windows.
  • the numerals three, six, nine and twelve appear in the window 17 located at the emplacement of the twelve in a conventional watch.
  • the numerals four and eight appear at their usual places and all other numerals appearing in one of the two windows 18 and 19 are either one more or one less than three, six, nine or twelve.
  • Some additional positions of the disc 11 can be reserved to display colored areas either to modify the aesthetics of the watch or to remind the user of an appointment.
  • the watch shown in FIG. 5 indicates either 12h 35min or 9h 35min.
  • the four numerals which alternatively appear in one of the three windows can be inscribed all together at the places of the windows, so that the disc 11 is not necessary. In this case the aesthetics may suffer.
  • the watch case 2 can be transparent in its top part as well as in its lower part, and the dial 8 can be omitted, so that the watch movement 1 shows to the viewer.
  • the watch according to the invention can also be equipped with a movement whose single hand rotates once in one, two, three, four, six or twelve hours.
  • the disc 11 may show the full hour indications in an arrangement in which the numerals expected to appear in the window 17 are, for instance, located on a different diameter than are the numerals expected to appear in the window 18 or the numerals expected to appear in the window 19. If furthermore the three windows l7, l8 and 19 respectively are each located on the same diameter as the numerals expected to appear in it, the disc 11 needs no angular limitation in its rotation, because the display of a numeral in a wrong window is not possible.
  • Another advantage of the present invention is that the same watch movement can be placed in different bezels permitting modification of the aesthetics or appearance of the watch.
  • the rim 5/6 can be designed as a toothing which meshes with a pinion afixed to a stem with a conventional crown traversing only the bezel 9.
  • the time setting is executed by rotating the crown, and not as shown in FIG. 3.
  • a watch comprising:
  • a watch case including a watch crystal
  • a hand means mounted within said case and visible through said crystal for indicating time
  • a watch movement means mounted within said case for moving said hand means
  • a bezel for supporting said case, said bezel including a mounting means for engaging said case but for allowing said case to be rotated relative to said bezel and an indicia means for displaying graduated indicia around said case and thereby indicating time by its positional relationship to said hand means.
  • a watch as claimed in claim 1 wherein said bezel mounting means has the further function of frictionally engaging said case to permit relative movement of said case in said bezel, and to permit removal of said case from said bezel.
  • a watch as claimed in claim 1 wherein said bezel comprises a ring and a disc.
