Electro-Seal ES-51½ Pocket Watch Crystal 45.4mm (1.787“) - New

Electro-Seal Electroglas ES-51½ Acrylic Pocket Watch Crystal - Round Lentille (which means lens) Open Face Case Crystal Size 1.787" or roughly 45.4mm, new in envelope. ES measured their crystals in inches unlike most others (like GS) who measures theirs in mm. This is roughly equivalent to a PKH series crystal from GS. These are NOS crystals and haven't been stored for 75+ years like other ones on eBay often are, although they can often be quite dusty and will need to be washed carefully before use. 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 a pretty good job of representing the item.
