Serial Number 505930 was reported as inaccurate.
Note: Grade: 180
Movement Finish: Nickel
Movement Finish: Nickel
Curator Response: Thanks for the report. This movement is gilt damanskeened. It is unclear whether the company would have considered this movement Grade 80 or Grade 180 (or an unknown grade). For the time being, these will be classified as Grade 80 since the 180 was still being produced at this time as a nickel movement.
Changes since this report was submitted:
Movement Finish changed from Gilt to Gilt Damaskeened
