ABSTRACT:
A motor actuates a wheel train which drives center hour and minute hands as in an ordinary analog-display watch. Another motor actuates a chronograph train which drives a chronograph sweep seconds-hand, a minute-register hand, and an hour-register hand offset toward 6 o'clock. A lever actuates a column wheel which starts and stops the second motor by means of a control lever integral with a stem. A hammer resets the chronograph gears. An electronic circuit comprises a liquid-crystal display element which displays the hundredths of a second when the chronograph is running or the date when the chronograph is not running.
