What do you think of the watch time?

Both watches and clocks have scales. The short hand is an hour hand, the long hand is a minute hand, and the long hand that keeps turning clockwise is a second hand. When the hour hand indicates the time, one circle is 12 hour, the minute hand represents five minutes, and one circle is 60 minutes, that is 1 hour. Every time the second hand makes a circle, it is one second, and a circle is 60 seconds. For example, the watch in the picture below is 3: 16 (because his hour hand points to scale 3 and the minute hand passes through scale 3, indicating 15 minutes).

Efficiency: In a normal watch, when the winding shaft is turned, it feels loose at first, and then gradually tightens. When it can't rotate forward, it means that the spring has been completely tightened.

Watch hands: There should be a certain gap between watch hands and glass, between three watch hands and between watch hands and dial. If they rub against each other, it will affect walking.

Tightness: This is to check whether the parts of the moving needle are installed normally.

Out-of-tune: By listening to the abnormal sound when the watch moves, you can only judge whether there is any special problem with the watch, but not whether it is good or bad.
