【発明の詳細な説明】 （産業上の利用分野） 本発明は時計用外装部品に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a timepiece exterior component.

た。(Prior Art) As a surface finishing method for a conventional watch exterior part, for example, a watch case, in the case of white finish, a nickel plating layer and a Pd plating layer are further applied on a brass or stainless steel surface as a base, In the case of golden finish, it is common practice to apply an Au alloy plating layer on the Ni plating layer on the surface of the brass undercoat, and each surface has a gloss finish effect.

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, it has come to be preferred that a watch case and a watch band, which are exterior parts for a watch, have a worn-out stainless steel color or a gold color feeling that is a retro antique feeling. . Since it was almost impossible to give such a feeling by surface treatment plating, generally, honing is unevenly applied on the watch case surface, and a Ni plating layer is applied as a base plating on it. A Pd plating or Au alloy plating layer was applied on the surface to express a retro tone.

も問題があった。However, with this method, the honing eyes appeared on the surface, and it was not possible to give the feeling of stainless steel or gold with a slightly cloudy color tone that was worn out and had scratches at random. A method of performing honing treatment after undercoating was also tried, but since the undercoating easily disappears by honing, the effect cannot be obtained unless the plating thickness is more than twice the usual thickness, and there is a problem in cost. .

解決せんとするものである。(Means for Solving Problems) The present invention uses a plating method in which a cathode current density is applied,
In a watch exterior part having a Ni plating layer and an Au plating layer formed on the surface, a Ni plating layer is formed on a base, and a finish plating layer made of at least one of Pd, Au and Au alloys is further formed on the Ni plating layer. The total plating thickness of the Ni plating layer and the finish plating layer is 2 to 5 μm, and the relative reflectance is 4 to 7,
The present invention proposes an exterior part for a watch and a manufacturing method thereof, which has a finished surface having a used color tone of semi-glossy retro tone of stainless steel or gold, and intends to solve the above problems by this. .

The present invention aims to obtain a watch case giving a retro antique feel, which is removed from the conventional glossy finish, and it has been considered impossible in the past. It was achieved by the conventional surface treatment by plating.

キに用いられたものでよい。The base of the watch case or the like used in the present invention is brass or nickel silver, which is the same copper alloy as the conventional one, 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, an Au plating layer and an Au alloy plating layer is formed on this layer. The Pd, Au, and Au alloys in this case may be those used in conventional plating.

レトロ調の使い古された色調効果は得られない。The thickness of the plating layer, including the base plating layer and the finish plating layer, is appropriately 2 to 5 μm, and it is necessary to set this range even when the finish plating layer is not a single layer. Outside this range, the worn-out color tone effects of the present invention, such as stainless steel and gold semi-gloss retro tone, cannot be obtained.

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 variously changed according to the intended color tone. For example, if you want a semi-glossy white color, apply a matte Ni plating layer and a glossy Pd plating layer on top of the brass base, or in the case of a golden color, apply an Au alloy plating layer on the matte Ni plating layer. Alternatively, there are various combination methods such as stacking Pd plating and Au alloy plating layer on the matte Ni plating layer, and it is not always necessary to make all matte plating. The term "matte Ni plating" as used herein means that a plating bath is used in which the compounding amount, which varies depending on the type of the brightener, is limited to about half of the conventional amount.

The amount of the brightener in the plating bath is adjusted within the above range, and the relative reflectance of the film surface is kept at 4 to 7 by using the plating bath.

Copper alloy plate with a 2 μm thick glossy Pd plating layer formed on the surface (without scratches on the surface)
Is used as a standard sample and an automatic goniophotometer (Murakami Color Research Laboratory) is used to measure 60 ° of the plating layer surface of the standard sample.
The regular reflectance with respect to the incident angle is set as 10, and the reflectance of the DUT with respect to this standard sample is said. After setting the regular reflectance to 10 in the standard sample, it refers to the numerical value obtained from the variable angle luminous intensity curve of the regular reflection direction with respect to the incident light of 60 ° on the plating layer surface of the watch exterior component treated by the method of the present invention, The plating layer of the conventional watch case has a semi-glossy tone (honed), which shows 9 or more, and the range of the relative reflectance of 4 to 7 in the present invention cannot be realized by the conventional technique.
