Serial Number 4917607 was reported as inaccurate.

Note: My 4917607 most definitely has Royal stamped on
it. It is a tu tone movement with no jewel count
listed on it. Do you believe Waltham would stamp a
lesser grade on a higher caliber watch?
Curator Response: Thanks for the report. If possible, please upload an image of the movement to your collection for further evaluation and documentation.
