Why quartz watch is more accurate than mechanical watch

Why quartz watch is more accurate than mechanical watch

The two are mainly different in structure. The quartz watch uses the quartz resonator 阼 as the time reference. The oscillation frequency of the quartz resonator is very high, generally 32768 Hz, while the oscillation frequency of the swing wheel hairspring of the mechanical watch is only 2.5~5 Hz. The higher the oscillation frequency, the more accurate the travel time, so the quartz watch has higher accuracy than the mechanical watch. In addition, the mechanical watch has a helix. When people string watches, the helix is also tightened. When the helix is released, it starts to drive the watch core to move. However, the speed of the spiral motion of the mechanical watch is inconsistent, which leads to the decline of the timing accuracy. Accuracy is also affected by such factors as temperature, location, wear of parts and other factors.

Why does the clock still have errors after adjusting the time

Why does the clock still have errors after adjusting the time

To illustrate the problem, it is necessary to understand why clocks and watches have errors. As you know, the mechanical clocks (including wall clocks, seat clocks, etc.) sold on the market are generally in a fixed position. However, due to the structural characteristics of the spring, the friction and fatigue between the materials and rings, the change of the output torque from strong to weak, and the friction between the spring and the gear during the transmission of the force distance will affect the accuracy of the clock travel time. In addition, climate, regional environment and location also affect the normal operation of the clockwork pendulum. The current quartz clock overcomes the weakness of mechanical clock and uses the extremely stable high-frequency vibration of quartz crystal as the time benchmark,

Why is the time different in each country

Why is the time different in each country

Because with the rotation of the earth, the sun rises in the east and sets in the west in a day. When the sun passes the highest point of the sky in a certain place, it is 12 local hours here. Therefore, there are different local hours on different meridians...
