Serial Number 689777 was reported as inaccurate.

Note: 689777 is marked 15 jewels
Curator Response: Thanks for the report and images. The "15 Jewels" marking is not consistent with other factory markings and was likely done at a later time. If possible, the jewel count would need to be verified by inspecting under the dial.
