I often receive inquiries from some customers, saying that my Panerai fake watches is inaccurate, either faster or slower, but after careful inquiry, I found that many of the time errors are actually within the standard range, then this What are the specific standards?
Because the quartz watch is electronically controlled, its time accuracy is relatively high, while the mechanical watch has a relatively poor time accuracy due to the mechanical swing principle. In addition, the larger the mechanical watch, the higher the accuracy of the time. Conversely, the smaller the accuracy is.
There are two main reasons for the inaccurate running time of automatic mechanical watches. One is the quality of the watch itself, such as automatic winding failure and pendulum failure, which can cause inaccurate running time; the second is the problem of the wearer. The former can be concluded through the inspection of replica watches relevant national inspection departments. If it is a quality problem, the merchant must return, replace, and repair according to regulations. The latter depends on the specific circumstances of the wearer, such as what kind of person is wearing it, and in what environment.
For the time error of clocks and watches, the current industry standard stipulates: The instantaneous error range of calendar mechanical watch I (men's watch) is: the error of the first-class product is -30 ~ +45 seconds per 24 hours; the error of the first-class product is -40 ~ +75 seconds per 24 hours; the error of the qualified product is -60 ~ +105 per 24 hours second. The continued travel time is greater than or equal to 36 hours. The instantaneous error range of the calendar mechanical watch II (medium-sized watch) is: the error range of the first-class product is -35блгл65 seconds per 24 hours; the error of the first-class product is -50блгл95 seconds every 24 hours; the error range of the qualified product is every 24 Hour error -70бл+135 seconds. The continued travel time is greater than or equal to 35 hours. The instantaneous error range of the calendar mechanical watch type III (Kun watch) is: the error of the first-class product is -40 ~ +85 seconds per 24 hours; the error of the first-class product is -60 ~ +115 seconds per 24 hours; the error of the qualified product is -80 ~ +165 per 24 hours second. The continued travel time is greater than or equal to 34 hours. The instantaneous error range of automatic mechanical watch I (men's watch) is: the error of the first-class product is -20блгл30 seconds per 24 hours; the error of the first-class product is -30блгл60 seconds every 24 hours; the error of the qualified product is гн50блгл90 every 24 hours second. The continued travel time is greater than or equal to 36 hours. The instantaneous error range of automatic mechanical watch II (medium-sized watch) is: the error of excellent products is -25блгл50 seconds per 24 hours; the error of first quality products is -40блгл80 seconds every 24 hours; the error of qualified products is -60блгл120 every 24 hours second. The continued travel time is greater than or equal to 30 hours. The instantaneous error range of the automatic mechanical watch type III (Kun watch) is: the error of the first-class product is -30блгл70 seconds per 24 hours; the error of the first-class product is гн50блгл100 seconds every 24 hours; the error of the qualified product is гн70блгл150 every 24 hours second. The continued travel time is greater than or equal to 28 hours. Regardless of the type of quartz watch, the instantaneous error range of the running time is: every 24 hours error of high-quality products-0.5 ~ +0.5 seconds; first-class product error-1.0 ~ + 1.0 seconds every 24 hours; qualified products every 24 hours Error -1.5 ~ +1.5 seconds.
