How should the accuracy of a replica Longines quartz watch be adjusted?

　　The accuracy of a quartz watch is higher than that of a mechanical watch. The margin of error is generally around a few seconds, with the 24-hour error typically being around 10.5 seconds. However, if the error of your quartz watch over 24 hours exceeds 12 seconds, it will need to be adjusted. Soreplica Longines quartz watchaccuracy be adjusted?

　　Adjusting the trimmer capacitor

　　Prise open the case back to locate the trimmer capacitor and make a positional mark. To reduce human influence, use a long, thin bamboo or plastic screwdriver to turn the trimmer capacitor slightly in one direction. After a few hours, check it against the standard radio time signal; if the error decreases, the rotation direction is correct, whereas if the error increases, you should turn it in the opposite direction. Once the correct direction of rotation for the trimmer capacitor has been determined, adjustments can be made. Initially, the angle of rotation can be slightly larger, and as the error gradually decreases, the angle of rotation should also decrease correspondingly, eventually amounting to no more than a gentle touch. Through subtle and repeated adjustments, high precision can be achieved. The time adjustment range of the trimmer capacitor is approximately within 12 seconds.

　　Adjusting the Fixed Capacitor

　　If the error of the replica Longines quartz watch is excessively large and exceeds the adjustment range of the trimmer capacitor, the fixed capacitor must be adjusted simultaneously. For a quartz watch that runs slow, the capacitance of both the fixed capacitor and the trimmer capacitor can be progressively reduced until they are removed entirely. Generally, it can be adjusted to run faster by about 20 seconds within 24 hours. Alternatively, a small 5-40 picofarad capacitor can be connected in series within the quartz crystal circuit to make the watch run faster. When a quartz watch runs fast, it is frequently because the fixed or trimmer capacitors have become loose or failed. A small 5-50 picofarad capacitor should be soldered in as a replacement, and the specific capacitance value must be determined through repeated testing. The replacement capacitor soldered in should be compact in volume and possess a high quality factor; high-frequency ceramic capacitors are suitable for this purpose.
