Rolex Oyster Crown White 5.3mm - New in envelope

Rolex White Oyster Crown, measures roughly 5.3mm in diameter as shown in images. Item is unused, NOS, in well worn envelope. See images for further details and perhaps even a P/N if you can read the writing. These often find their way to the bottom of watch parts and this envelope shows it. I know these are often listed for a seemingly silly amount of money but I'm listing mine at what I hope to get for it, especially in light of the original envelope. That said, I do accept offers. Images to an adequate job of representing the item.
