That said, they are quite likely very dirty and need serious cleaning.  I have a supply of crystals that numbers in the hundreds of thousands so I can usually supply just about any size Watch Crystal you need (glass or acrylic) so feel free to inquire. Images do an adequate job of representing the item.\u003cbr\u003e\u003c\/p\u003e","brand":"Universal","offers":[{"title":"Default Title","offer_id":49040448520500,"sku":"CGC-UNIMIC230-02","price":10.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2026-02-1217.19.14.jpg?v=1770945854","url":"https:\/\/www.vintagetimeparts.com\/products\/universal-vintage-small-glass-watch-crystal-12-5-16-28-0mm-nos","provider":"Vintage Time Parts","version":"1.0","type":"link"}
