1. Since 18K gold is moderately flexible and easy to shape, many complicated and delicate gold jewelry are mostly made of 18K gold. In addition, changing the formula and proportion of other metals can make it appear in rich colors such as platinum, rose gold, pink gold, orchid gold, purple gold, etc. It also breaks the single tone of pure gold and adds infinite variability to Kgold. and possibilities, it also caters to people’s taste for change and fashion. 2. The gold plating layer is usually between 2UM. The gold-plated shell has beautiful color, most of which are golden yellow (international standard is 1N14 or 2N18). Generally speaking, any electroplating will fade, but a good gold plating layer has strong alkali and acid resistance and will not fade easily within 12 years. With poor electroplating treatment, the bottom layer may fade within one month. For example: if the gold plating layer is within 2UM, it will gradually fade after half a year; if the gold plating layer is 35UM, it can last for 12 years; if the gold plating layer is 57UM, it can last for 35 years; if the gold plating layer is more than 10UM, it can last for more than 5 years; 20UM or above can be maintained for 10 years. Of course, if acid, alkali, salt or corrosive gas is encountered during use, replica watch the retention life of the gold plating layer will be greatly reduced. The edges and corners of the appearance are susceptible to friction and fade easily.

3. The gold-plated layer on gold-plated watches is mostly 14K gold. In addition to 58.5% pure gold, this gold also contains a certain amount of silver. After 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 a gold-plated watch, you should avoid contact with chemicals and waste gases, such as gas, liquefied gas, and sulfur soap, and keep the gold-plated watch dry and clean. It is best to wipe it with a flannel 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 avoid sweat corrosion and loss of the original luster of the fine imitation watch.

4. The yellow-plated layer of a yellow-plated watch is a metal film composed of copper, zinc, and aluminum alloy. If it is not well maintained, it will easily fade and lose its luster. Before wearing a yellow-plated watch, the watch case should be wiped clean with a clean soft cloth, and a layer of colorless nail polish should be evenly applied. Let it dry before wearing it, and then apply it every 12 months. After such treatment, not only can the color of the yellow-plated watch be maintained without being worn, but it can also increase its surface brightness. At the same time, it can prevent sweat and moisture from intruding into the watch in hot summer
