Description

  The present invention relates to a jewel fixing method and a wristwatch for fixing a jewel to a base (for example, a watch dial, a transparent plate for protecting the dial), and more particularly, a jewel having a tapered tapered surface. The present invention relates to a jewelry fixing method for fixing to a pedestal and a wristwatch.

  Conventionally, when fixing a gem such as diamond, ruby, emerald, sapphire to some pedestal such as a wristwatch or a decoration, a method is generally used in which a nail embedded in the pedestal is locked to the jewel. .

  If the jewel is fixed to the pedestal using the nail as described above, the nail covers a part of the jewel and the shine of the jewel is impaired, and the nail protrudes from the top or side of the jewel. There are problems such as being caught on clothing, problems such as the claw being detached from the jewel due to the above-mentioned catch, and the fixing of the jewel on the pedestal being troublesome. It was.

On the other hand, there is also known a jewel fixing method in which a hole is formed in a pedestal without using the above-mentioned claw, and a jewel is adhered to the bottom of the hole (for example, see Patent Document 1). By fixing the jewel in this way, the problems in the case of using the above nails can be solved.
