Borel P 410\u003c\/strong\u003e - \u003cstrong\u003e44\u003c\/strong\u003e½\u003cstrong\u003e\u003c\/strong\u003e Lentille (which means lens) Chevee (which, in this context, means slight depression) acrylic Pocket Wrist Watch Crystal, 41.0mm diameter, new in envelope.  Someone has altered the Dennison size by 1\/4 size which I'm not sure that's entirely accurate, but it doesn't change the actual size in mm. These are clear NOS crystals and haven't been stored for 75+ years like other ones on eBay often are. Can supply just about any size Watch Crystal you need (acrylic or glass) so feel free to inquire. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do an adequate job of representing the item.\u003c\/p\u003e","brand":"J.
