Serial Number 1479849 was reported as inaccurate.

Note: Note: the reference movement you show is not
correct for a Model 4. what you are showing is a
model 5. the halfmoon click on a model 4 is on
the side of the ratchet wheel closest to the
balance bridge. the Model 5 (as you are showing)
is on the opposite side. the reference EA, for
Model 4, (from the 'book'), is 461. the model 5
is EA 463
Curator Response: Thanks for the report. Yes, I am aware of this and hope to update it soon.
