DIAL: Original silver color dial with black color arabig numbers and batons as markers (see pictures, please). Dial is signed IRIS at twelve position and shows some patina. As seen at the pictures, hour and minute hands are at the top of the dial, allowing the other half of the dial to be just for the seconds hand.

This kind of duo dial or doctor's watches were especially useful for measuring short periods of time because of enlarged visibility of second hands. Original hands.
