SUC Rocket Crystal RS 564-10 for SWISS wrist watches 21.4 x 19.4mm - New

SUC Rocket RS 564-10 Fancy Wrist Watch Crystal for unspecified SWISS wrist watches, measures 21.4 x 19.4 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 Rocket 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 an adequate job of representing the item.
