Serial Number 455661 was reported as inaccurate.

Note: Marked 15 Jewels
Curator Response: Thanks for the report and images. This movement is more consistent with the Grade 80 classification (11 Jewels). The marking on the barrel bridge does not appear to be a factory mark, and there are no known grades offered in this model with 15 jewels and nickel plates. It is more likely the movement is a Grade 80 and marked "15 Jewels" after it left the factory. If you happen to pull the dial to confirm the jewel count one way or the other, please let me know.
Changes since this report was submitted:
Grade changed from 70 to 80
