Mercury Flat Octagon Crystal N1901 (GS N320) for Swiss Watches - 19.0 x 19.0 mm - New

Majestic Watch Crystal Company Mercury Processed Flat Octagon shaped Acrylic Crystal N1901 for unspecified Swiss wrist watch and wrist watch cases, measures 19.0 x 19.0 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 (N320).  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.
