SUC Rocket Crystal RMS 117-10 for ELGIN case #4638 - 20.3 x 19.4mm - New

SUC Rocket RMS 117-10 Fancy Wrist Watch Crystal for ELGIN model case #4638 and perhaps other wrist watches as well, measures 20.3 x 19.4 mm, new in very frail envelope. Note that this is equivalent to a GS CMX 317-17. 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. Free shipping in the continental US on most all fancy acrylic crystals. Images do a pretty good job of representing the item.
