What does 18K gold-filled mean, and will 18K gold-filled watches fade?

Hello everyone, this is Bokey Watch Industry. Earlier, we introduced whether gold-plated watches will fade. Today, through this article, we will introduce the application of 18K gold-filled technology in watches and its differences from gold-plated watches. As we mentioned before, watches using gold-plating technology will not fade easily. However, with long-term wear, the gold-plated layer on the watch case and strap will gradually wear out, and after several years, fading will still occur. This is unavoidable and is part of the product’s depreciation process. Nevertheless, some consumers still have higher requirements, hoping that their watches will never fade like 18K solid gold watches. At this time, to meet these consumers’ needs, the 18K gold-filled technology naturally emerged in the market.

What is 18K gold-filled?

18K gold is a common metal alloy material made by mixing gold with other metals. This alloy contains 75% gold, along with other metals such as silver, copper, and zinc. The process of covering the surface of other metals (usually non-gold metals, as we often see in watches) with a layer of 18K gold through special chemical techniques is what is known as the 18K gold-filled process.

What is the difference between 18K gold-filled and gold-plated?

First of all, the biggest difference between 18K gold-filled and gold-plated lies in thickness. The thickness of gold-filled is about 5 microns or more, which is dozens of times thicker than gold-plated. It is more resistant to wear, has higher surface hardness, and is theoretically close to being never wearing out.

Secondly, the material of 18K gold-filled contains 75% gold content. It can provide a precious metal inspection certificate recognized by national certification institutions, with a unique serial number that can be checked nationwide through the network.

Therefore, if you have high requirements for gold-colored watches, you can choose custom gold-filled. Wanshangming can provide watch enthusiasts with a very perfect 18K gold-filled service for watches, meeting your strict requirements for watch quality.
