For your consideration is this Elgin pocket watch dial.
This measures about 38mm in diameter and appears to be a size 10.
The dial feet are good and under the 9/10, 35/35, and 54-minute markers.
There are some faint hairline cracks running from the sunk toward the top of this dial and also one on the left side starting at the 11 and running down toward the 10.
Please see the photos for more detail.
