Do you know how to choose a watch?
Check appearance
The appearance can be checked from the watch case, watch glass, dial, hands, etc.
Sensitivity
The sensitivity of a watch refers to how soon or late the balance wheel in the watch “starts” on its own. One way to check is to shake a watch that has not been wound before and stop moving. With the help of the shaking force, observe the movement of the second hand; if the second hand stops moving within a short period of time, it means that the watch is fully released. After the watch can be completely loosened, the sensitivity is relatively high; if the second hand continues to move for a long time, it means that the watch cannot be completely loosened after it is fully wound, the sensitivity is not high, or the internal mechanism is malfunctioning.
efficacy
In a normal watch, when turning the winding stem to wind the mainspring, it feels relatively loose at first, and then gradually tightens up. When it can no longer continue to move forward, it means that the mainspring is fully wound up.
Hands
There should be a certain gap between the hands of the watch and the watch glass, between the three hands of the watch, and between the hands of the watch and the dial. If they touch each other, it will affect the movement.
Tightness
This is to check whether the mechanical installation of the needle moving part is normal.
Moving sound
Listening to see if there is any abnormal sound when the watch is moving, you can only judge whether the watch has any special problems, and cannot tell whether the watch is good or bad.
