仕上効果を得ていた。(Prior art) Conventionally, in the case of a white finish for exterior parts of watches, such as watch cases, a Ni plating layer is applied to the underlying brass or stainless steel surface, and then a Pd plating layer is applied on top of the Ni plating layer. In the case of golden finishing, it is common practice to apply an Au alloy plating layer on the Ni plating layer on the surface of the brass base, thereby obtaining a glossy finish effect on each surface.

たはＡｕ合金メッキ層を施して、レトロ調を表現してい
た。[Problems to be solved by the invention] However, in recent years, people have come to prefer worn-out stainless steel and gold colors that give a retro and antique feel to watch cases and watch bands, which are the exterior parts of watches. . It was almost impossible to achieve this kind of feeling with surface treatment plating, so for boat fishing, the surface of the watch case was honed unevenly, a Ni plating layer was applied as a base plating, and then A Pd plating or Au alloy plating layer was applied on top to give it a retro look.

があった。However, with this method, the honing marks appeared on the surface, and it was impossible to create the impression of stainless steel or gold, which has a slightly muddy tone that looks like it has been worn out and has scratches at random. A method of honing treatment after base plating was also attempted, but since the base plating was easily destroyed by honing, the plating thickness was reduced to 2 times the normal thickness.
The effect could not be obtained unless it was doubled or more, and there was also a problem in terms of cost.

The present invention proposes an exterior part for a watch, which has a total layer thickness of 2 to 5 μm, and a relative reflectance of 4 to 7, and a method for manufacturing the same, thereby solving the above-mentioned problems. It is.

キによる表面処理によって達成したものである。The exterior parts for watches of the present invention will be explained in detail below regarding watch cases.The purpose of the present invention is to obtain a watch case that gives a retro antique feel that breaks away from the conventional glossy finish, and which has been previously considered impossible. This was achieved by surface treatment using plating.

金は従来のメッキに用いられたものでよい。The base of the watch case, etc. used in the present invention is brass or nickel silver, which is the same copper alloy as in the past, and Ni is used as the base plating.
A plating layer is applied, and a single layer or a composite layer of any one of a Pd plating layer, a U plating layer, and an Au alloy plating layer is formed on this layer. The Pd, u, and Au alloys used in this case may be those used in conventional plating.

れない。The appropriate thickness of the plating layer, including the base plating layer and the finish plating layer, is 2 to 5 μm, and it is necessary to keep it within this range even when the finish plating layer is not a single layer. Outside this range, the retro tone effect aimed at by the present invention cannot be obtained.

無光沢メッキとする必要はない。ここでいう無光沢Ｎｉ
メッキとは、配合する光沢剤を通常の約半分程度に制限
したメッキ浴を使用することを意味する。The plating treatment on the surface of the watch case can be changed in various ways depending on the desired color tone. For example, if you want a semi-gloss white color, you can apply a matte Ni plating layer on the brass base and a glossy Pd plating layer on top of it, and if you want a golden color, you can apply an Au alloy plating layer on the matte Ni plating layer. There are various combination methods, such as applying an Au alloy plating layer on the matte interplating layer, or stacking Pd plating and Au alloy plating layer on the matte Ni plating layer. It is not necessary to use matte plating. Matte Ni here
Plating means using a plating bath in which the amount of brightener added is limited to about half of the usual amount.

．． Examples include primary brighteners such as sodium 6i naphthalene trisulfonate, and secondary brighteners such as coumarin, 2-butyne, 2-butyne-1,4diol, ethylene cyanohydrin, thiourea, quinoline, and pyridine.
本発明でＰｄ、 Ａｕ、 Ａｕ合金による無光沢メッキ
を行う場合はこれらの光沢剤を通常の１／２程度の範囲
内で調整したメッキ浴を用いる必要がある。When performing matte plating using Pd, Au, or an Au alloy in the present invention, it is necessary to use a plating bath in which the content of these brighteners is adjusted to about 1/2 of the normal amount.

は実現できなかったものである。What is important in the present invention is that the total thickness of the plating layer is adjusted within the range of 2 to 5 μm, and the relative reflectance of the film surface is adjusted to 4 to 7 by adjusting the amount of brightener in the plating bath. It is to maintain it. In this case, the relative reflectance refers to the value obtained from the variable angle light curve in the regular reflection direction for 600 human rays of light on the surface of the plating layer using an automatic variable angle photometer (manufactured by Murakami Color Technology Research Co., Ltd.). The plating layer of the watch case exhibits a semi-gloss finish (honed) of 9 or more, and the relative reflectance range of 4 to 7 in the present invention has not been achieved in the past.

る。Figure 1 shows variable angle light curves measured using an automatic variable angle photometer (GP-1R) on the surfaces of the plated layer according to the present invention and the Pd plated layer according to the conventional method. Example 1.2, C is the conventional curve. According to this, it can be seen that the surface of the present invention is rough and exhibits a semi-glossy and luxurious appearance.

You can get a luxurious and calm retro-style watch case that you've never seen before.
