Serial Number 1268180 was reported as inaccurate.

Note: Regulator is different from the one pictured on
your site. Tried to post a picture, but your
upload system is poor.
Curator Response: Looks like you were able to upload the image. Your movement features the index on the balance bridge instead of the plate. The model diagram only represents the movement plate design and regulator/jeweling can be different depending on the grade.
Changes since this report was submitted:
Movement Finish changed from Gilt or Nickel to Gilt
