How can you tell if a watch is real gold?

To tell if a watch is real gold, first examine the back of its case. Some makers add metal purity hallmarks, such as “18K” or “750,” to their gold watches, while others use unique codes or style numbers to provide information about their materials. By researching the markings on your watch using trusted online resources, you can often determine what metals it features. If you run into any difficulty, a certified appraiser or knowledgeable jeweler can help you. Shop a large collection of gold watches on 1stDibs.
