The gold-plated layer on the gold-plated watch is mostly 14K gold. In addition to 58.5% pure gold, this gold also contains a certain amount of silver. After the silver reacts with some volatile industrial waste gases in the air, a black silver sulfide film will be produced on the surface, causing the gold-plated watch to lose its golden luster. Therefore, when wearing gold-plated watches, you should avoid contact with chemicals and waste gases, such as coal gas, liquefied gas and sulfur soap, and keep the gold-plated watches dry and clean. It is best to wipe it with a velvet cloth once a week.
In addition, the chloride in sweat is very corrosive to gold-plated watches. When gold-plated watches are stained with sweat, they should be wiped clean in time to prevent sweat from eroding and causing the watch to lose its original luster.
The yellow-plated layer of the yellow-plated watch is a metal film composed of copper, zinc, and aluminum alloys. If it is not well maintained, it will easily fade and lose its luster. Before wearing a yellowed watch, the case should be wiped clean with a clean soft cloth, and evenly apply a layer of colorless nail polish, and then wear it after drying, and apply it once every 1 to 2 months. After such treatment, not only can the color of the yellowish-plated watch be maintained without wear, but it can also increase its brightness on the surface. At the same time, sweat and water can be prevented from invading the surface in hot summer.
