Abstract

The timepiece of the invention includes at least a seconds hand arranged to respond to a chronograph mechanism. It comprises a single motor which receives at least two pulses per second so as to cause the seconds hand to advance by at least two steps per second. The system as disclosed enables an improvement in readability of the precision of time intervals on the one hand and on the other hand assures certain operation of the chronograph while using a stepping motor dimensioned to drive a simple timekeeper.
