    Rose gold color is very popular in the watch industry in recent years. Many brands use PVD technology to deposit rose gold coatings on the stainless steel case and strap. It is called IP rose gold in industry and its technology is very mature. The rose gold coating generally consists of a gold imitation layer and a rose gold layer. The underlying imitation gold layer is generally TiCN, which mainly help increase the hardness and wear resistance of the rose gold.

    1. Crown gold, the gold content is 22K (91.667%), this proportion of gold is used by the British Henry VIII (1526) for the first time to the gold coin casting.

     

    2. 18K rose gold, the most common and most typical rose gold, the gold content is 18K (75%), but it contains about 4% of silver and 21% of copper, to show a beautiful pale pink rose color.

     

    3. 14K red gold, the gold content is 14K (58.33%), and other added metal is copper (41.67%).

     

    The rose gold targets of some PVD coating factories also contain some rare elements to achieve different colors or to change the performance of the coating. This is one of the reasons that there are some differences in the plating color of each PVD factory on the market.
