This is a french onion by David Vivier.
I understand that early French watches were wound through the center arbor. That is how this one is wound, but I think the mechanical layout is unusual? The fusee is in the middle and chain wraps around an offset portion of the mainspring barrel.
Is there an expert out there that can clarify whether this is the typical mechanical configuration for a center-arbor-wound onion? Also, please could you help determine its age?
Thank you,
Chris
