Note: The watch is at least 17j with high rise gold
jewel settings and the damascening looks similar
to the "American Grade". There is a large bevelled
gold cap on the winding. The movement appears to
be custom factory finished as an employee's watch.
The movement grade is marked AWWCo.
Curator Response: Thanks for the report. If possible, please upload an image of the movement to your collection for further evaluation and documentation.
