Serial Number 18015202 was reported as inaccurate.

Note: I missed one error in my prior report. My
movement has 16 jewels and is so marked. I
believe the Lady Waltham was only made as a
16-jewel model and all catalogs of the era list it
as such. Without taking the dial and canon pinion
off, the lack of a 17th jewel would not be
obvious.
Curator Response: Thanks for the report. This information has been noted in the research notes for this run.
