What causes time variance in DW watches?

　　Most DW watches are quartz watches, and generally speaking, the time variance is very small. However, during daily use, time variance is still practically unavoidable. So what generally causes time variance in DW watches? Below I analyse the causes of time variance in DW watches, hoping it will be useful to you.

　　Causes of timekeeping deviations in DW watches

　　Generally speaking, there are two main reasons for timekeeping deviations in DW watches.

　　First, issues with the quality of the watch itself.

　　Problems such as a faulty automatic winding mechanism or a defective oscillating weight can cause inaccurate timekeeping.

　　Second, issues related to consumer usage.

　　If it is a quality issue with the watch itself, it can be determined through testing by relevant national inspection departments. If it is indeed a quality defect, the retailer must provide returns, exchanges, or repairs in accordance with regulations. The latter depends on the specific usage conditions by the consumer, such as who is wearing it and the environment in which it is worn.

　　What is a normal timekeeping deviation for a watch?

　　Regardless of model, the instantaneous timekeeping deviation ranges for quartz watches are as follows: for premium grade, the deviation per 24 hours is -0.5 to +0.5 seconds; for first-class grade, the deviation per 24 hours is -1.0 to +1.0 seconds; for qualified grade, the deviation per 24 hours is -1.5 to +1.5 seconds.

　　From the above standards, it can be seen that because quartz watches are electronically controlled, their timekeeping accuracy is relatively high, whereas mechanical watches rely on mechanical oscillation principles, so their timekeeping accuracy is relatively lower. In addition, the larger the mechanical watch, the higher the accuracy; conversely, the smaller it is, the lower the accuracy.
