Abstract

PURPOSE: To ensure the discrimination between the alarm awaiting and stopping conditions by indicating the discrimination with the difference in the advancing conditions of a second hand.
CONSTITUTION: An alarm staff changing lever 14 attached to a plate 12 is guided in a cut portion 12 and is so mounted as to have a vertical elastic force with respect to a diamond-shaped portion 3d of an alarm staff 3. There are provided an alarm sliding pinion 4, which has its rectangular hole 4c engaging with an angular portion 3c, an alarm sliding pinion lever 5, which is operative to support the sliding pinion 4, and an alarm staff lever 6 which is operative to urge the alarm staff 3 toward a crown 21. Thus, if the crown 21 is depressed from the position 21-2 to the position 21-2 to the position 21-l, the alarm staff lever 6 is brought into contact with a alarm contact spring 15 so that an alarm set confirming sound is generated and so that a second hand 22 is changed from one second step advancement to an n second step advancement thereby to indicate that the alarm is brought into its alarm awaiting condition. When the alarm set time comes, an alarm switch mounted in a rear wheel train is turned on to operate a buzzer. If the crown 21 is again depressed into the position 21-1, the alarming sounds are stopped, and the second hand 22 restores its one second step advancement.
