This is a One of a Kind Piece! Cyma Watch from the Early 1900's- On The Back is Engraved with the Date 1926 making it ATLEAST 98 Years Old. As you can see by the pictures it's in pretty darn good condition- Case and Crystal In Tact Just Light Wear as Pictured. I am not sure of the metallic Makeup all I know is it's Cyma brand made in Switzerland and engraved 1926, outside of that and the history of the makers, I don't know much else about this. I DID NOT Clean This or Alter It Or Anything. I Purchased This from a Watch Collectors Estate- Took Pictures of It and Put it in a Display Box.
