Just came across this very interesting watch to early wristwatch collectors.
I have no connection to this auction but thought you's should see this untouched example
of a center secs watch from 1910.
Can anyone find the original patent for Depose No9846? where's Bobbee?
or reference to the US Patent on the movement?
Earliest center seconds wristwatch I've ever saw.
