Insist on G-S The Original Still the Best

The following G-S plastic, round watch crystals are measured in millimeters: AT, CDE, CFT, CT, DT, ET, MT, ST, TR, TT, WT.
The G-S plastic, round watch crystal numbering system for HC, KT, PHD, PK, PKH, VT, W, and XHD is unique and was originated by G-S in the 1920's. Please see the attached chart [PDF format] for G-S round crystal sizes and their corresponding millimeter sizes.
G-S watch crystals are available at watch material distributors all over the United States and Canada.
A note for watch collectors, hobbyists and enthusiasts: We are a manufacturer to specifications and distributor of plastic and glass watch crystals. We do not actually employ a watchmaker who would know exactly what crystal fits specific watch cases/models. Many of our watch crystals fit many different brands and models. We always recommend taking watches to a qualified watchmaker or jeweler who fits watch crystals to ensure that a new watch crystal is fitted properly. Many jewelers provide this service. The good news is that there are thousands of stock plastic and mineral glass watch crystals, so chances are good that a local jeweler who repairs watches should be able to find a suitable match and fit your watch properly.
Below you will find a brief overview of the available G-S plastic crystal styles and size ranges.
