GS Fancy Crystal CX788 for GRUEN 235 / 911- 21.7 x 19.9 mm - New

GS Flexo CX788 Fancy Acrylic Crystal for select GRUEN case no. 235/911 tank models and likely other wrist watches as well, measures 21.7 x 19.9 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.
