Serial Number 884878 was reported as inaccurate.

Note: Marked 17 jewels. Appears to be perhaps a Grade
974, 975 or 976, definitely not a 992.
Curator Response: Thanks for the report. Your serial number is "881878" - not "884878." I will update your collection record accordingly.

Note: The 992 in my collection has the word “EXTRA”
engraved on movement below the crown wheel. The
case also is engraved with the word “EXTRA” .
Both appear to be factory engraved.

Note: It's all accurate above. Just to add it's a
two-screw crown wheel but 3-post, lever set, and
definitely RR grade marked adjusted 5 positions.
