Serial Number 2586863 was reported as inaccurate.

Note: The movement finish seems to be a light gold wash
throughout with darker gold color in the
checkerboard center pattern (see photo)...would
this be considered "two-toned"?
Curator Response: Thanks for the report and images. Yes, indeed. This movement would be classified as "two-tone."
