Abstract

The watch has a timer (11), a position-dependent switch (22), a timing circuit (23) with a counter, and a flip-flop connected to the output of the counter, as well as a control switch (21), which is connected to the output of the timing circuit, for activating the time display. The switch (22) applies a switching signal (24) whenever the watch assumes a specific position. Upon expiry of a specific time interval from the occurrence of the switching signal, the counter supplies a resetting signal to the flip-flop. After receiving the switching signal (24), the latter generates an activation signal (25) and interrupts the latter upon receipt of the resetting signal. The display (18) indicates the time indication supplied by the timer (11) as long as the control switch (21) maintains the activation signal (25). <IMAGE>
