<p>PROBLEM TO BE SOLVED: To provide, at a low cost, a thin type portable watch capable of obtaining high-grade brightness and color tone even when thin precious stones are used for decorative members such as hour characters and alleviating a variation in color even when the number of colored decorative members is used, thereby enhancing a viewing quality of the decorative member.SOLUTION: The portable watch fixes a precious stone such as a diamond as an hour character index on an obverse surface of a display plate 100 for watch via a pedestal 106, and forms light reflecting means composed of a reflection layer 108 on a rear side and a side face side of a precious stone 106a. The reflection light of the precious stone 106a is effectively utilized to be brilliant by providing an air layer 107 between a rear face of the previous stone 106a and the reflection layer 108. When the number of colored precious stones is used, the formation of light reflecting means having the same color as that of the previous stone provides a portable watch that supplements and alleviates the variation in color of the colored precious stones.</p> |
