Abstract

PURPOSE: To prevent discoloring of silver by using clean water of specific purity in washing process of silver plating.
CONSTITUTION: In the production of silver dial plate for watch, for example, pure water having purity of 106Ω×cm or more is used in many stages of washing processes after silver plating and after layer treatment to prevent silver discoloring. This completely prevents discoloring due to impurities present in washing water used for silver-plating finished dial plate for watch.
