Vintage lot of 140 Cylinder G-S Acrylic Watch Crystals, mostly CMX, CMT, CMY, CMF, CY CF, CX, CS. Most packages have never been opened, some are open but appear to contain a new crystal. See pictures for specific crystal part numbers. Lot varies by part numbers. These appear to be very old from package condition.
This is from a former watchmaker's repair parts collection and have been in storage for the past 25+ years. Selling lot per items pictured. See my return policy.
