Serial Number B204848 was reported as inaccurate.

Note: Serial number B204848 is a 16s Ball-Waltham 19
JEWEL movement that is listed in the Jones Horan
auction (lot 143) that will begin on 16 Feb 2023
through 23 Feb 2023. This movement is a 19 jewel
movement. The corresponding WALTHAM serial number
is 13204848 and if you put that in the serial
number search, it correctly identifies the
movement as a 19j, Official Standard movement.
Furthermore, the published list of Ball Waltham
serial numbers which shows both the Waltham and
Ball serial numbers identifies the 27th run from
serial number B204301 - B206000 as a mixed run of
both 17 and 19 jewel movements. Looks like this
run of Ball Serial numbers in the database needs
some work/updating. *****@aol.com
Curator Response: Thanks for the report. This information has allowed for further refinement of this run to provide more granularity for future researchers.
