In general, MIM steel will not rust, and after polishing, its metallic luster will reappear. However, the watch chain and case made of fine steel are easy to be scratched, which is generally more conspicuous, seriously affecting the appearance of the watch. Therefore, if there are scratches on the steel strap and case, it can only be polished.
