G-S Plastic Watch Crystals

Insist on G-S – The Original – Still the Best

G-S Supplies has been manufacturing and distributing plastic watch crystals since the early 1920's.

Our warehouse in upstate New York has in stock over 8,000 sizes in 48 different crystal styles.

Our crystals fit many watch brands and models, from classic watches and retro watches to the latest designer models.

G-S Cylinder, Flat, and PA Waterproof watch crystals have unique alphanumeric ID numbers. Please see Catalog 2002 for a complete, sequential reference guide with actual size images of each crystal.

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 distribution houses all over the United States and Canada.

A note for watch collectors, hobbyists, and enthusiasts: Unfortunately, we do not employ a watchmaker or crystal fitter at our factory. We are a precision plastic optics molder. We stock our crystals by style and size, not by brand name and model number. Your local watchmaker, crystal fitter or jeweler can help you determine which crystal you require.
