Serial Number 997987 was reported as inaccurate.

Note: Your diagram of a movement and the movement whose
serial number I inputed are different movements
due to the way the balance spring is attached and
the way the regulator is attached
Curator Response: Thanks for the report. The diagrams are simply representations of the movement. The regulator and jeweling may appear differently on your watch.
