(Prior Art) Conventionally, in the above-mentioned portable timepiece represented by a wristwatch,
As shown in FIG. 4, the movement a has an assembly structure in which the movement a is directly fitted and incorporated in the accommodating portion b 1 that is stepped in the watch case b, and then sealed by the glass lid c or the back lid. . Since the step processing accuracy of the accommodating part b 1 requires the fitting of the movement a completely, it requires high accuracy, specifically about ± 0.03 mm, which is a factor that increases the cost of the wrist watch and the like. It was.
Due to the recent diversification of mobile watch materials (eg, colorization), and the desire to have beautiful colors and to prevent scratches on the watch case surface, hard-to-grind materials such as cemented carbide and ceramics. Due to this, the watch case b is often manufactured.

(Problems to be solved by the invention) Incidentally, in manufacturing the above-mentioned watch case a made of a difficult-to-grind material, one by one is pressed according to the shape and size of the movement b to be fitted, and then the fitting surface is fitted. The process of grinding to achieve the above-mentioned processing accuracy is taken, but this causes a cost increase more than ever before, and movement a has various functions other than the clock function (for example, calculation function, calendar function). Etc.) has been added and the shapes have become various, and the difficulty of processing has become more and more remarkable. Therefore, a drastic improvement in the fitting assembly structure has been strongly desired.

(Operation) The portable timepiece configured as described above is assembled by first mounting the fitting ring in the timepiece case and then fitting the movement in the ring of the fitting ring. In this case, the dimensional difference of the movement that differs depending on the function is absorbed by fitting with a fitting ring that is easy to process, and a movement and fitting ring assembly with a common constant outer diameter is configured, making the watch difficult to process. By eliminating the need to process the case for each movement with different dimensional differences, it is possible to greatly improve the productivity of the watch case by consolidating, and even if there is cost pressure due to the increase in the number of parts, the overall productivity can be improved. By absorbing the cost increase, the manufacturing cost can be reduced and the quality of the product can be stabilized.
