Selection of alarm clock:

(1) Check the appearance first: the bell shell is bright and uniform in color, without paint peeling, discoloration and scratches. The clock face should be clean, with even scale and clear handwriting.

(2) Check the sensitivity: slightly start the clockwork, and the second hand will start to move, which proves that the sensitivity is high. A clock with high sensitivity takes a long time.

(3) Check out of tune: place the clock from left to right, face up and down. If the sound of walking in all directions is consistent, even without noise, it means that walking is normal.

(4) Check whether the needles are in contact: when the hour hand and minute hand move, the hour hand, minute hand and second hand overlap (three needles overlap), and a certain gap should be kept between the three needles, and no friction is allowed. At the same time, there should be a proper gap between the pointer and the clock face and glass.

(5) Check the alarm: dial the alarm surface to 3, 6, 9, 12 respectively, and then dial the alarm surface to these places. If the alarm error is within 5 minutes, the alarm is normal.

(6) Check the alarm sound; The alarm sound should be clear and loud, and there should be no dumb sound or hollow sound.

(7) Check the tightness of needle spoon and noise spoon: the tightness should be moderate. If the needle spoon is loose, it means that the elastic force of the compression spring on the central wheel is insufficient, which will cause the minute hand to move immobile or slowly when the second hand moves. If you release the alarm key, the alarm disc will rotate with the hour hand and the minute hand. But if they are too tight, they are inconvenient to use.
