ぐれた材料が使用でき処理も簡単である。In the present invention, a coating film containing particles having soft magnetism or hard magnetism is formed on at least the externally exposed part of the watch side by a method such as electrodeposition, and the watch is given the function of protecting the watch from external magnetic fields. Compared to conventional watch parts made by processing soft magnetic materials and hard magnetic materials, materials that are superior in terms of workability and cost can be used and processing is easier.
（従来の技術〕 従来、時計用側としては主として黄銅、洋白。(Conventional technology) Traditionally, the main materials used for watches were brass and nickel silver.

。Stainless steel and other materials were used, but recently there has been a problem with watches stopping due to external magnetic fields, and as a countermeasure to this problem, dials, back lids, sides, etc. are made of anti-magnetic materials. Especially on the side, it has high magnetic resistance (2000
Gauss~), soft magnetic materials such as ferritic stainless steel, chromium-iron alloys, permalloy, etc.
i! ! Trade magnetic materials are used. For example,
Such a configuration is disclosed in Japanese Patent No.-43070.

It was far inferior in terms of polishability, had limitations in terms of freedom of design on the watch side, and had the drawbacks of high processing costs.
本発明はこのような問題点を除去し、ｆｒｇ４な時計側

The watch side was coated with a coating containing magnetic particles.
ここにおいて、前記塗膜が従来のものにかわり、耐磁性
を保持する作用を果たすものである。Here, the coating film functions to maintain magnetic resistance in place of the conventional coating film.
以下実施例により本発明の詳細な説明する。The present invention will be explained in detail below with reference to Examples.

子を含む塗膜を形成した。The watch side, which is made of conventionally used materials with good workability, such as brass, is subjected to surface treatment to achieve the desired surface finish (9), masking the areas necessary for decoration, and applying metal coatings such as iron-cobalt, iron-nickel, nickel-boron, etc. A coating film containing soft magnetic and hard magnetic material particles was formed.
このように形成した時計側を、耐磁性材料で形成された
文字板、うらぶたと組み合せて耐磁性をテストした所、
５００ガウスの耐磁性が得られた。We tested the anti-magnetic properties by combining the watch side formed in this way with a dial and back lid made of anti-magnetic material.
Magnetic resistance of 500 Gauss was obtained.

るという意味で効果的である。Here, as a method for forming a coating film, electrodeposition coating, which is performed by adding the particles to an anionic or cationic electrodeposition coating liquid, is effective in the sense that it forms a uniform coating on three-dimensional objects such as sides. be.
また塗膜の厚みとしては、２０ミクロン程度以上あれば
耐磁効果は出るが、より厚くなるとその耐磁効果が高く
なる。Further, as for the thickness of the coating film, if it is about 20 microns or more, the antimagnetic effect will be obtained, but the thicker the thickness, the higher the antimagnetic effect.
（発明の効果）
以上述べてきたように本発明によれば、比較的安いコス
トで耐磁効果の高い時計側が可能になる。(Effects of the Invention) As described above, according to the present invention, it is possible to provide a watch with a high anti-magnetic effect at a relatively low cost.
なお、このような塗膜の形成は、文字板の裏面。Note that this type of coating is formed on the back of the dial.
うらぶたの内面に形成しても、同様効果が得られること
はいうまでもない。It goes without saying that the same effect can be obtained by forming it on the inner surface of the lining.
