The style of the clock is earlier, likely mid to late 1920’s on the absolute outside. At one point this was a smoking setup that was mounted on the back of the front seat in a sedan and is now missing the lighter and ashtray - it looks like it was gutted to be hung in a house as 28Chrysler pointed out. It would also have been from a car more in the medium price range (which Duesenburg was definitely not a medium price range vehicle) such as Buick, low series Packard, etc. The wreath bezel might indicate Cadillac, but it is just an impression of mine…
Good luck!
