How to Pick a Clock


(1) Check the appearance first: the color of the clock case is bright and uniform, and there is no peeling, discoloration and scratches. The clock face should be clean, with even scales and clear handwriting.


(2) Check the sensitivity: Start the mainspring a little, and the second hand starts to move, which proves that the sensitivity is high. A clock with high sensitivity lasts for a long time.


(3) Check the running time sound: Place the clock face left and right, front, back, up and down. If the sound is the same in all directions and in all directions, and there is no noise, it means that the clock is running normally.


(4) Check whether the needle is touching: Move the hour and minute hands so that the hour, minute hands and the second hand overlap (the three needles overlap), and a certain gap should be maintained between the three needles, and no rubbing is allowed. At the same time, there should be proper clearance between the needle and the clock face and glass.


(5) Check the trouble: dial the trouble face to 3, 6, 9, and 12 respectively, and then move the hour and minute hands to these places. If the error of the trouble is within 5 minutes, the trouble is normal.


(6) Check the sound of the alarm; the sound of the alarm should be clear and loud, without mute or empty sound.


(7) Check the tightness of the needle key and the alarm key: the tightness should be moderate. If the needle key is loose, it means that the compression spring on the center wheel is insufficient, and the second hand moves but the hour and minute hands do not move or move slowly. If the alarm key is loose, the dial surface will rotate with the hour and minute hands. But if it's too tight, it's inconvenient to use.
