How do you know an original gold wristwatch?

To know an original gold wristwatch, try placing a magnet near it, as gold is not magnetic. If there is a strong attraction, your watch may be gold-filled or crafted from another metal. Hallmarks on your timepiece can also help you determine what it's made of. Gold watches often have a stamp that says 14K, 18K, 583 or 750. However, there are other gold hallmarks as well. Researching the purity of the marks on your watch using trusted online resources can be helpful during the identification process. Alternatively, you can have a certified appraiser or experienced jeweler evaluate your watch for you. On 1stDibs, shop a collection of gold watches.
