KK Vintage Glass Small Pocket Watch Crystal 15-0/16 (33.8mm) - NOS

KK Vintage Small Glass Pocket Watch Crystal size 15-0/16 = ~33.8mm with a thickness of ~1.7mm, which is pretty thick for this size crystal, new old stock.  Mi-Concave profile crystals come with a bevel, as shown, and are the most common ones found on vintage watches. These come from glass crystal cabinets that are easily well over 80 years old, so they give real meaning to the term NOS. That said, 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 since I can't list them all. Images do a pretty good job of representing the item.
