Definitions

  • the watch glass is placed on a main body of the watch case with an O-ring interposed therebetween and a rim member having an inner profile complementary to the profile of said non-circular glass element is force-fitted over the main body of the case to surround said noncircular glass element, whereby the non-circular glass element only of the watch glass is exposed to the sur face of the watch case.
  • the present invention is intended to eliminate such difficulties of the conventional non-circular waterproof watch cases and has for its object the provision of a water-proof watch case having a non-circular glass profile, which comprises a main body of the case, a watch glass consisting of an ordinary round glass element and a non-circular glass element laminated thereon, and a rim member having an inner profile complementary to the profile of said non-circular glass element, said watch glass being liquid-tightly secured to said main body of the case by means of said rim member which is fitted over said watch glass surrounding said non-circular glass element.
  • the water-proofnessis ensured by the round glass element and the profile of the exposed watch glass can be varied optionally by changing the profile of the non-circular glass element which is exposed through the rim member. Therefore, by practicing the present invention it becomes possible to obtain a water-proof wrist watch having a non-circular dial, such, for example, as an oval, rectangular or triangular dial.
  • FIG. 1 is a plan view showing an embodiment of the waterproof wrist watch case according to the present invention.
  • FIG. 2 is a side view of the wristwatch case with a portion shown in vertical cross section taken on the line A-A of FIG. 1;
  • FIG. 3 is a side view of the wrist watch case with a portion shown in horizontal cross section taken on the line 8-3 of FIG. 1.
  • reference numeral 1 designates a main body of the case, 2 a rim member of the case, 3 a round glass element, 3' a non-circular glass element, 4 an O-ring cooperating with the rim member, 5 a dial, 6 an hour hand, 7 a minute hand and 8 a crown.
  • the water-proofing structure of the watch case according to the present invention is the same as that of the conventional waterproof wrist watch case comprising a round glass. In the present invention, however,
  • the water-proofness of the rim member is achieved in the following manner: Namely, the O-ring 4 is disposed beneath and along the peripheral edge portion of the ground glass element 3 and the rim member 2 is forcefitted over the main body 1 of the case while compressing the O-ring 4 between said round glass element and said main body of the case, whereby a liquid-tight engagement is produced between said rim member and said main body through said glass and O-ring.
  • the water-proofness of the case is ensured by the employing the round glass element and the non-circular glass element 3 is laminated on top of said round glass element. Therefore, a waterproof wrist watch having a non-circular dial of beautiful appearance, as shown in the drawing, can be obtained.
  • the water-proofness of the case is positively secured by the round glass element, an aesthetic factor only need be considered in the fabrication of the irregular glass element to be laminated on the round glass element and the rim member. Therefore, by employing the water-proof wrist watch case of the invention, wrist watches having faces of many different profiles can be produced on the basis of mass production and in adcircular glass profile comprising a case with a main body, a watch glass having a circular glass element and a non-circular glass element laminated thereon with said watch glass extending over the face of the watch, and wherein the circular portion is of a single thickness and the non-circular portion is the combined thickness of said circular element and said non-circular element laminated thereon.
  • a waterproof wrist watch case according to claim 1, wherein the watch glass is affixed to the case such that a sealing member is interposed between said circular glass element and the main body of the case.
  • a waterproof wrist watch case according to claim 2 including a rim member having an inner profile complementary to the profile of the non-circular glass element.
  • a waterproof wrist watch case having a noncircular glass profile comprising a case with a main body, a watch glass having a circular galss element and a non-circular glass element laminated thereon and said watch glass extending over the face of the watch, a rim member having an inner profile complementary to the profile of said non-circular glass element, with a sealing member disposed beneath and along the peripheral edge portion of the circular glass element and the rim member disposed in a force-fit over the main body of the case in such a manner as to compress the sealing member between said round glass element and said main body of the case, and wherein the circular portion is of a single thickness and the non-circular portion is the combined thickness of said circular element and said non-circular element laminated thereon.
