Watch Crystals

Hi,

I’m hoping someone can lead me to a chart that breaks down the sizes
of watch crystals into measurements I can understand. I’ve been
looking at watch crystals on line and find 16’s, 20’s 24’s, but
don’t know what they are in mm’s. I’ve spent far too much time
searching for a breakdown, to no avail. The only thing I’ve
succeeded at is making my eyes very tired!

I’d like to use them to create small shadowboxes.

Thanks!
