Serial Number 3591621 was reported as inaccurate.

Note: Wouldn't this movement be classified as
"two-toned" with the nickel background and
gold/nickel checkerboard pattern in the middle?
(see photos) Otherwise everything seems to be
correct.

Curator Response: Thanks for the report. Yes, indeed. This run has been updated to include the two-tone finish.
