Serial Number C10702 was reported as inaccurate.

Note: mine is a wrist watch, un adjusted and not
isochronic.

Curator Response: Correct. The 554 was commonly used as a wristwatch movement (nothing in the database is incorrect on this point). Some of the Grade 554 movements are not marked for adjustments. This has been noted in the research notes for the run.
