Mercury Flat Crystal H1252 (GS H380) for ILLINOIS - 12.5 x 19.7 mm - New

Majestic Watch Crystal Company Mercury Processed Flat Acrylic Crystal H1252 for ILLINOIS & OLLENDORFF wrist watch and wrist watch cases, measures 12.5 x 19.7 mm, new in envelope. I have a batch of these Mercury crystals that are really quite nice and are comparable to GS crystals, which Majestic realized they were competing against, hence the GS P/N is included as well (H830).  Pretty much all crystals require some light filing / sanding for proper fit. I have thousands upon thousands of wrist and pocket watch crystals as well as watch parts of all kinds, and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
