Serial Number 187102 was reported as inaccurate.

Note: Movement #187102: Configuration: Open Face,
Movement Setting: Stem Set
Curator Response: Thanks for the report. If your dial does not feature a seconds bit, the movement is still a hunting configuration with a special factory dial to allow for an openface orientation. The pendant is perpendicular to the position of the 4th wheel.
