Definitions

  • the invention relates to a wristwatch with a watch case, in which a movement is held, which carries a dial with hands, which is covered with a watch glass held at the edge of the watch case, and with a bracelet and a closure element for the bracelet.
  • the watch case consists essentially of wood.
  • This configuration has the advantage that the entire wristwatch is extremely light and, due to the natural nature of wood, is generally well tolerated by the skin, in contrast to metallic wristwatches, which in extreme cases can trigger allergic reactions in sensitive users at the point of wear.
  • the watch case is made of wood
  • a suitable choice of the type of wood enables the case to be matched to the other watch components in terms of shape, color and design, which is only possible to a limited extent with metallic wristwatches with, for example, steel cases and with additional processing operations.
  • the closure element of the bracelet is made of solid wood or recombined wood, so that here, on the one hand, a weight saving results compared to the component usually made of metal, and on the other hand skin compatibility is ensured and a uniform design of the closure element and housing is made possible becomes.
  • the bracelet consists of natural products, for example cork and / or leather. These natural products are also kind to the skin and complement the natural character of the wristwatch.
  • the watch case 10 is made of a hardwood, such as teak or ebony, which has two recesses of different depths and different diameters on its top for receiving the clockwork, the dial, the hands and the watch glass.
  • the hole going to a smaller depth with the radius R2 and the deeper hole with the smaller Radius R1 create an annular contact surface 10B for the dial.
  • the clockwork sits on the floor 10C directly or via a movement ring.
  • a recess is provided which is open towards the underside of the housing 10 and in the opposite side surfaces of which holes 10D are provided for receiving the spring bars 31, 32 of a spring bar, around which the two halves 30A, 30B of the bracelet are wound are.
  • These spring bars 31, 32 snap into the bores 10D in a known manner and thus establish a non-positive connection between the housing 10 and the bracelet 30A / 30B.
  • the connection point of the bracelet halves 30A / 30B is covered by the upper region of the housing 10.
  • One half 30A of the bracelet carries a closure element 20 in a known manner, which according to the invention is also made of solid wood or recombined wood, expediently of the same type as the housing 10.
  • FIG. 2 shows a partial section through the watch case according to FIG. 1, the individual components being used to complete the watch:
  • a work ring 13 On the bottom 10C of the housing 10 there is a work ring 13, which in turn carries the clockwork 11 and can also have a closed bottom.
  • the dial 12 On the top of the clockwork 11 is the dial 12, which extends with a radius of approximately R2 over the annular contact surface 10B to the edge thereof.
  • the hands 14, 15 and 16 are arranged on the pointer shaft of the movement 11, and the dial 12 is finally covered with a watch glass 17 which has circumferential grooves 19 in the form of screw claws on its outer circumferential area, by means of which it enters the slightly frustoconical beveled inner wall the upper hole with radius R2 can be pressed or screwed in.
  • the truncated cone-like undercut of the inner edge of the upper bore also creates a snap-in effect by which the watch glass 17 is pressed onto the dial 12 and the contact surfaces between the watch case 10 and the watch glass 17 simultaneously act as a sealing surface.
  • a metal insert 18 (reinforcement ring) is inserted in the contact area of these two components, which counteracts fatigue of the watch glass 17.
  • the bore 10A for receiving the setting shaft (not shown) for the clockwork 11 has at its outer end (mouth region) a metal sleeve 10E which carries a crown 10G which is supported on the circumference of the metal sleeve 10E via a sealing ring 10F and provides the force connection Manufactures (not shown) adjusting shaft, so that in a known manner by rotating the crown 10G, the adjusting shaft rotates about its axis AA (Fig. 1) and causes the corresponding mechanical or electronic processes in the clockwork 11.
  • FIG. 3 shows a second exemplary embodiment for the wooden housing 10, namely from glued veneer layers 40, which have been broken out in a terrace-like manner in FIG. 3 in order to illustrate the layer character.
  • the grain direction of the veneer layers indicated by arrows is rotated by 90 ° in the case of successive veneer layers 40.
  • 3 shows the grain direction of the lower veneer layer in direction P, that of the next veneer layer in the direction perpendicular to it, the veneer layer above it in turn in direction P etc.
  • This cross-gluing of individual veneer layers ensures a high dimensional stability of the watch case.
  • the closure 20, which is naturally mechanically highly stressed can also be produced from veneer layers glued in this way.
  • Both the one-piece solid wood housing according to the embodiment 1 and 2 as well as the housing constructed from glued veneer layers according to the exemplary embodiment according to FIG. 3 can be protected by treatment with suitable substances, such as glazes, impregnations or its surface properties can be influenced.
  • suitable substances such as glazes, impregnations or its surface properties can be influenced.
  • a suitable coloring is also possible in a simple manner.
  • the invention In connection with a bracelet made of natural products, for example leather or cork, the invention thus creates a wristwatch whose contact surfaces with the skin of the user consist exclusively of natural materials and which is extremely light.
