APC Round Pocket Watch Crystal PP 51, 45.0mm - New

APC Round Pocket Watch Crystal PP 51, very nice quality low-dome pocket crystal, measures 45.0mm, new in envelope. The PP 51 is basically the same as a GS 51 although these are a bit lower profile. These are perfectly clear crystals that haven't been stored for 75+ years like other ones on eBay often are. I 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.
