Serial Number 19107163 was reported as inaccurate.

Note: Adjustments should be 5, hairspring is Breguet
overcoil and not Lossier, and the damaskeening and
plate design are different than the photo
suggests.
Curator Response: Thanks for the report. If possible, could you upload images of the watch to your collection? There is an example from this run that is marked "6 Positions" and features the Lossier hairspring. Thanks!
