These plastic GS watch crystals are great for watchmakers. These PHD Hi Dome crystals can be compression fit into most watch cases. They are flanged making them a good choice to replace old style mechanical watch crystals on mechanical watches that do not open in back. These genuine GS plastic crystals can be used longer, because you can easily buff scratches and mars out of them, saving you time and money.
Below is a chart showing the discontinued crystals and some that we still have limited stock.
