Diel made cases that usually housed other Swiss makers movements, predominately those from the 1920's and 1930's. 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 (Y450).  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.\u003c\/p\u003e","brand":"Majestic Watch Crystal Co.","offers":[{"title":"Default Title","offer_id":48948328595764,"sku":"CPC-MAJY1685-11","price":6.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2025-11-1716.47.18.jpg?v=1763427127","url":"https:\/\/www.vintagetimeparts.com\/products\/mercury-flat-crystal-y1685-gs-y450-for-diel-16-8-x-12-2-mm-new","provider":"Vintage Time Parts","version":"1.0","type":"link"}
