Lost gold watch with black leather strap and minor scratch on glass, possibly left on a table by the window in a café in Center City, Philadelphia.

I lost my gold watch with a black leather strap while visiting a café in Center City, Philadelphia yesterday afternoon. I think I might have left it on the table by the window. It has a minor scratch on the glass but is otherwise in great condition. I really hope to get it back as it was a gift from my grandfather.
