GS Fancy Crystal CF500 for GRUEN 864 / 415 - 23.6 x 20.3 mm - New

GS Flexo CF500 Fancy Acrylic Crystal for select GRUEN case no. 864/415 barrel models and likely other wrist watches as well, measures 23.6 x 20.3 mm, new in open envelope. These are perfectly clear crystals that haven't been poorly stored for 75+ years like other ones on eBay often are. Pretty much all GS crystals require some light filing / sanding for proper fit. 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 an adequate job of representing the item, oh, and free shipping in the US on most Fancy Crystals.
