PURPOSE:To make an accurate display in up to minute units with one alarm hand providing a means which displays only minute units of alarm time with the alarm hand. CONSTITUTION:When the alarm time is set to 2:30, a mode selection switch(Sw) S1 is operated to set '1' in a mode selection counter 37. Consequently, an Sw control part 33 outputs a mode signal (c) and a set pulse signal (f); and the signal (c) opens an AND gate 75 and the signal (f) is passed through an OR gate 51 and inputted to an RS-FF circuit 52 as a set signal. Then when a correction Sw S2 is operated, 2 o'clock is stored 16. Then, the Sw S1 is operated to put the timepiece in alarm correction mode and then the control part 33 outputs a mode signal (d) and a set pulse signal (g). The signal (d) opens an AND gate 73 through an OR gate 72 and is sent to a minute display body 23 through an OR gate 22. Further, the signal (g) is inputted to an FF52 through the OR gate 51 to set the FF52. Then, 30min are stored 15 with the Sw S2 and the alarm hand is set to 30min.
