This size is probably for cases 12s or near to it, and the Mi-concave is the typical profile of a stock glass crystal.  While still likely well over 100 years old, in my 40 years of experience with them I've not found the older crystals to be any more or less brittle than anything you could find today. I likely have several of these so the one you get may differ slightly from the images.  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":"VTF","offers":[{"title":"Default Title","offer_id":49058793718068,"sku":"CGC-VTFMIC385-03","price":10.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2026-03-0819.15.50.jpg?v=1773022774","url":"https:\/\/www.vintagetimeparts.com\/products\/vtf-vintage-beveled-glass-pocket-watch-crystal-17-1-16-38-5mm-nos","provider":"Vintage Time Parts","version":"1.0","type":"link"}
