GS Flexo CY900-90 Fancy Wrist Watch Crystal for select SWISS barrel shaped cases, measures 26.5 x 20.5 mm, new in sealed envelope. These are perfectly clear crystals that haven't been 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.
