Serial Number 20745733 was reported as inaccurate.

Note: Marked as 17 jewel. Note: serial number looks a
little “off,” leading 2 doesn’t align or
appear to be quite same size.

Curator Response: Thanks for the report. Looks like the barrel bridge has been swapped on this movement, borrowing from a Grade 345. The core movement is a Grade 315, as indicated by the damaskeening pattern and consistent with factory serial lists.
