SUC Flat Crystal S 438 for GRUEN Clayton, Courtney, Viscount - 19.6 x 18.6mm - New

SUC S 438 Flat Acrylic Crystal for GRUEN model Clayton, Veri-Thin models Courtney & Viscount and perhaps other wrist watches as well, measures 21.4 x 21.4 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 can supply just about any size Watch Crystal you need (acrylic or glass) so feel free to inquire. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
