SUC Rocket Crystal RMC 104-7B for GRUEN case #425/592 - 23.0 x 21.2mm - New

SUC Rocket RMC 104-7B Fancy Acrylic Crystal for GRUEN model case #425/592 and perhaps other wrist watches as well, measures 23.0 x 21.2 mm, new in envelope. These are perfectly clear crystals that haven't been stored for 75+ years like other ones on eBay often are. This one is equivalent to a GS CMX356-44. 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.
