Note: Movement is a plugged 23 jewel, with wind
indicator. Additionally it is marked 6 positions
(!) next to the serial number, and + Lossier Inner
Terminal Hair Spring on the mainspring winding
wheel, in the manner of 16s Model 1908 Vanguards.
Assuming that it has a Lossier hairspring, it
probably was finished later than 1907.
Curator Response: Thanks for the report. If possible, please upload an image of the movement to your collection for further evaluation and documentation.
