Claims (11)

  A dial ring that comes into contact with the outer edge of a display panel for a watch from above, and includes a base layer provided on the counter face of the base of the dial ring and a decorative layer provided on the surface side of the base layer, and the decorative layer is provided with laser light. A pattern ring is formed by forming a pattern-like exposed portion on the underlayer by irradiating the irradiated portion of the decorative layer to evaporate.   By irradiating a part or all of the exposed portion of the underlayer with laser light to evaporate the irradiated portion of the exposed portion of the underlayer, a pattern-like exposed portion is formed on the facing surface of the substrate of the facing ring. A turn ring characterized by the formation.   The counterfeit ring according to claim 1 or 2, wherein the pattern-like exposed portion of the underlayer is made of at least one of a pattern, a number, a sentence, and a mark.   The counter ring according to any one of claims 1 to 3, wherein the underlayer includes at least one of a luminous luminous layer, a metal layer, and a coating layer.   The dial ring according to any one of claims 1 to 4, wherein the underlayer is colored.   The base layer is composed of a plurality of layers, and the upper base layer is irradiated with a laser beam in a pattern to evaporate the irradiated portion of the upper base layer, thereby forming a pattern on the lower base layer. The dial ring according to any one of claims 1 to 5, wherein an exposed portion is formed.   The dial ring according to any one of claims 1, 2, and 6, wherein the laser beam is an excimer laser beam.   In a method for manufacturing a turn ring that comes into contact with an outer edge of a display panel for a watch from above, a step of forming a base layer on a turn side of a base of the turn ring and forming a decoration layer on the surface side of the base layer; And a step of irradiating the decoration layer with laser light in a pattern to evaporate the irradiated portion of the decoration layer, thereby forming a pattern-shaped exposed portion on the base layer.   By irradiating a part or all of the exposed portion of the underlayer with laser light to evaporate the irradiated portion of the exposed portion of the underlayer, a pattern-like exposed portion is formed on the facing surface of the substrate of the facing ring. The manufacturing method of the turning ring according to claim 8, further comprising a forming step.   A step of forming a plurality of underlayers as the underlayer, and a lower layer of the underlayer by irradiating a portion to be irradiated by irradiating an exposed portion of the upper layer of the plurality of underlayers with a laser beam in a pattern. And a step of forming a pattern-shaped exposed portion on the surface. 10. A method for manufacturing a turn ring according to claim 8 or claim 9. The method of manufacturing a turn ring according to any one of claims 8, 9, and 10, wherein the laser beam is an excimer laser beam.
