2. Description of the Related Art Conventionally, a device in which an annular exterior member such as a bezel or a decoration ring is attached to the viewing side of a watch or the like is known.
As a method of fixing such an exterior member, for example, a method of fixing to the case with an adhesive or the like, or a method of press-fitting and fixing via a waterproof ring (packing) or the like is common.
For example, in the case of an exterior member made of a relatively light material such as resin, it is possible to prevent the case from falling off only by such adhesive fixing or press-fit fixing.
However, when the exterior member is heavy and formed of a metal material, it is difficult to securely fix it by adhesive fixing or press-fitting, and the adhesive part gradually peels off or loosens during use. As a result, the exterior member may come off and fall off.

In this regard, for example, Patent Document 1 is provided with a cover member that is formed of a resin or the like after the exterior member (bezel) is attached to the case and covers the outer peripheral surface of the exterior member (bezel) and the outer peripheral surface of the case. The structure which fixes a cover member and a case with a screw | thread is disclosed.
Patent Document 2 discloses a configuration in which an exterior member (bezel) is fixed to a case with a screw.
If such a structure is employ | adopted, an exterior member (bezel) can be fixed to a case reliably, and falling off from a case can be prevented.
