However, in the case of replacing the watch body from the back side of the watch side, the watch body is replaced by pushing the watch body into or out of the watch side by hand. The press-fit allowance could not be so large so as not to damage the watch, and there was a risk that the watch would be detached from the watch side during transportation and dropped, thus damaging the watch body. In particular, when the wear due to repeated replacement reduces the press-fitting allowance, the risk is further increased.

[0006] In the case of a wristwatch, the wristwatch can be replaced only with the wrist removed, and a wristwatch having a bezel larger than the wristwatch housing hole diameter of the wristwatch cannot be fitted.

On the other hand, when the timepiece is replaced from the front side of the timepiece, only the engaging member is engaged, and the timepiece is not latched over the entire circumference of the timepiece. Not suitable for type watches. In the case of using the frame base, there is a problem that the thickness of the timepiece increases accordingly.

Accordingly, an object of the present invention is to solve the above-mentioned conventional problems in a portable timepiece in which a timepiece can be exchangeably mounted on the timepiece, and to remove the timepiece from the timepiece when carrying or using it. The watch body can be easily replaced with one hand, and the watch body with a bezel larger than the watch body storage hole diameter on the watch side can be fitted, eliminating the risk of increasing the thickness of the watch. It is in.
