PURPOSE:To obtain a time piece having a thin edge, and to improve a design of the timepiece without deteriorating a waterproof function, by forming a vapor plating layer, a wet plating layer, a protective plating layer, etc. on the outside peripheral part of a windshield glass. CONSTITUTION:A vapor plating layer 5 is formed on the lower face of the outside peripheral part, and the outside peripheral of a windside 1 of the glass 2, and the reverse side. Subsequently, in the vapor-plated glass 2, a wet plating layer 6 is formed on only the upper face of the plating layer 5. On the other hand, the BS side 1 is formed mechanically to a side shape, and thereafter, a protective plating layer 3 is formed. As for the BS 1 which has been brought to protective plating, a liquid solder 7a is applied to the part which is joined to the glass 2. Thereafter, the glass 2 on which the plating layers 5, 6 have been formed is placed on the BS 1 to which the solder 7a has been applied, and heated, and the glass 2 and the BS side 1 are joined. After the solder junction, a finish plating layer is formed on the surface of the BS side 1 by using a metal of a necessary color tone, by a wet or gaseous phase plating. |
