corum bubble skull The quartz watch and the tuning fork will vibrate according to a certain law. When the quartz crystal is affected by the battery power, it will also generate regular vibration. The quartz crystal vibrates up to 32,768 times per second. We can design a simple circuit to calculate the number of vibrations. When it counts to 32,768 times, the circuit will send a message to let the second hand go forward for one second. Because the vibration of quartz is quite regular, even a cheap quartz watch, the error rate within one day will not exceed 1 second.In the mid-eighties, due to the rise of Japanese quartz electronic technology, a large number of quartz electronic watches entered the market. The Swiss traditional watch industry, especially quartz electronic watches, suffered a great impact and almost collapsed. However, the Swiss watch industry always insisted on its own high precision.

Pointy style.In the 1980s, the quartz crystal watch movements produced by the Swiss ETA movement manufacturer were: 255411, 255441, 255111, 976.001, 210.001, 282.001 and so on. The movement generally adopts a logic frequency modulation circuit, and the precision control system adopts concealed type. The precision control system is implemented in the IC circuit without manual adjustment of the precision of the circuit board, which greatly improves the accuracy and stability of the circuit board, and completely changes the traditional manual. ulysse nardin marine diver replica

Adjust the drawbacks caused by trimming capacitors. The minimum operating voltage is also set in the circuit board IC circuit to start the R.T test point, which is the main means to verify whether the mechanical drive train is working properly and the battery life is required to obtain important data. The battery has been out of power for less than one year. First, the battery factor should be excluded, such as the battery life limit. Secondly, the movement of the movement, the dryness of the lubricant, and the friction coefficient of the mechanical transmission system increase, which is the main reason for the battery life. The movement should be cleaned and maintained.

The fast travel time is mainly due to the change of the frequency of the quartz resonator in the circuit board. The reason is that the two pins of the quartz resonator are loose or the quartz resonator sealing tube is not well sealed, which will change the frequency of the quartz resonator. Another is that there is a problem with the control accuracy system in the IC circuit, and it is also possible to change the resonant frequency of the quartz to replace the circuit board. http://www.watchgetluxury.com


Slow walking has a phenomenon of stealing, mainly the internal organs of the movement, the metal surface of the rotor is cut or there is a short circuit inside the coil, which is necessary to replace the circuit board with the movement cleaning. The second hand has a reverse phenomenon, which is mainly due to the geometrical deformation of the stator piece or the change of the inside of the stator piece material, so that the magnetic field line changes the pit positioning problem, which is the main reason for the second needle to fall away, and the stator piece should be replaced.

Today, there are many people wearing watches, but all kinds of malfunctions due to wrong wearing, such as: walking fast, entering the water, being magnetic, the appearance of the watch is damaged, and so on. So how to repair the watch? What tools are needed to repair the watch? fake breitling navitimer watches
