Causes Of Time Errors In Certina Watches

Certina mechanical watches on the market. Due to the structural characteristics of the mainspring, the material, the friction and fatigue between the coils, the change in the output torque from strong to weak, and the friction generated by the mainspring and gears during the transmission of the force distance, all will affect the accuracy of the clock. In addition, the climate, regional environment, and location also have an impact on the normal operation of the Certina clockwork. The current quartz clock overcomes the weakness of mechanical watches, uses the extremely stable high-frequency vibration of quartz crystals as the time reference, and divides the frequency by a frequency-dividing circuit to once per second, and then drives the gear through a micro-stepping motor or scanning , Pointer, indicating time, even so, because the quartz crystal used is affected by temperature changes, errors will occur, usually 15 seconds per day. This is allowed.
为什么 Why is the Certina mechanical watch not electronically calibrated, and what is the error? The daily error of Certina quartz electronic watch is less than 0.5 seconds, which is one tenth of that of Certina mechanical watch. This is mainly due to the high and stable oscillation frequency of quartz oscillator in quartz watch. The principle of high frequency and accurate time is a principle found in the long-term study of how to improve the accuracy of timepieces. The higher the frequency of the oscillator, the more stable the oscillation, the stronger the anti-interference ability, and the more accurate the watch. The oscillation frequency of Certina quartz electronic watch is 32768Hz, which is 10,000 times higher than the frequency of 3Hz per second of ordinary fast pendulum mechanical watches. Therefore, quartz electronic watches are much more accurate than Certina mechanical watches. In addition, due to the structural problems of mechanical Certina watches, due to the gravitational force of the earth, the horizontal and vertical positions will produce a disparity. The spring is tightened to loosened, and the torque is unbalanced. The impact of vibration, etc., even if the mechanical watch raises some frequencies, it is impossible to reach the accuracy of the quartz electronic watch. Certina watches that are always within minutes are virtually non-existent. There is an error range for both mechanical and stone watches, and this range varies from country to country. Generally speaking, as long as the mechanical watch is full Under the circumstances, the travel time is not more than 30 seconds per day, and the standard is basically up to 30 seconds. The quartz watch meets the standard when the battery is fully charged and the speed is not more than 0.5 seconds. Therefore, whether it is a Certina mechanical watch or a Certina quartz watch, as long as their error is within the above two standard ranges, we can say that the watch is qualified to run. On the contrary, it indicates that the Certina watch has a problem when it is gone, and it must be adjusted by the repair and maintenance department.
