These pocket watch crystals are great because they can be glued into most watch cases, because they are perfect for open face mechanical pocket watches, and because you can easily buff scratches and mars out of them for longer. These genuine plastic crystals can be used to replace old style open face pocket watch crystals, saving you time and money.
