SUC Extra Heavy Lucite Crystal S 557 for ILLINOIS wrist watches and perhaps other wrist watches as well, measures 21.2 x 18.2 mm, new in envelope. These are perfectly clear crystals that haven't been stored for 75+ years like other ones on eBay often are. Pretty much all SUC crystals require some light filing / sanding for proper fit.

I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Free shipping in the continental US on most all fancy  crystals. Images do an adequate job of representing the item.
