According to China's industry standards, the daily error of the quartz watch belongs to the first class within 0.5 seconds, the error is 1 second, and the error is 1.5 seconds. The normality of the quartz watch error should be within 0.5 seconds per day. Why is this error occurring? What should I do if there is an error in the quartz watch?Quartz watch error rangeQuartz watch is not divided into models, the instantaneous error range is: the error of each product is -0.5 ~ +0.5 seconds per 24 hours; the error of first-class products every 24 hours -1.0 ~ +1.0 seconds; the error of qualified products every 24 hours -1.5 ~ +1.5 second. From the above criteria, it can be seen that since the quartz watch is electronically controlled, the travel time accuracy is high, and the mechanical watch has a relatively poor travel time accuracy due to the mechanical swing principle. In addition, the larger the mechanical watch, the higher the accuracy of travel time. On the contrary, the smaller the accuracy, the lower the accuracy. breitling bentley replica watches
