Abstract

PURPOSE:To obtain an alarm watch which is capable of clearly indicating the alarm set while checking whether there are troubles in an alarm setting switch or not by differentiating the motion of a hand with an ON signal of the switch. CONSTITUTION:Upon the closing of an alarm setting switch 12, an ON pulse of the switch 12 is applied on a clock terminal of an FF58 in a time limiting circuit 24 and the output Q of the FF58 is turned to a high level to set divide by 30 counter 64, the output of which is inverted after one minute, while AND gates 40 and 42 of a control circuit 8 are closed and opened respectively. A specified division level output from a division circuit 4 via the gate 42 is applied to a driver circuit 14 to turn on the switch 12 for the setting of the alarm. For one minute after that, a secound hand moves by an increment of 2 secs. once per 2 secs. This enables clear indication of the alarm set while cheking can be done on whether there are troubles in an alarm setting switch or not.
