    摘要: A watch case supports a rotatable disc rotatable every 12 or 24 hours. A pointer is provided driven concentrically with said disc every hour. A fixed reference member is provided to indicate the position of the disc. Numerals in the disc may be imprinted upon a sheet to show the relative position of the disc, pointer, and fixed reference number.
