Serial Number 7480421 was reported as inaccurate.

Note: I just accidentally hit the "yes" button- but this
movement is not an 11 jewel- it's clearly marked
(and has) 15 jewels. Otherwise the information
appears to be correct.
Curator Response: Thanks for the report. This information has been noted in the research notes for this run.
