Information

People always strive for perfection when they are in a customized Digital sport watch, and choose from the best. But how can you choose a watch with satisfactory quality? Usually, people only judge the quality of the watch by listening to the sound of the watch while it is running, which is unscientific. Because of the quality of the watch, it is important to see the accuracy of its actual time. The sound of the watch is balanced, clear and free of noise when the watch is running, which can only indicate that the watch is not malfunctioning, but does not indicate the quality of the watch. It is used as a method to select a watch.

customized Digital sport watch

1. Check the exterior parts of the customized Digital sport watch
The appearance of a customized Digital sport watch can be checked from the case, mirror, dial and hour, minute and second hands. The case should be free of sand holes and obvious scratches, and the edges and corners should be symmetrical; the screw joints between the back cover and the upper case should be close; the distance between the two watch rings and the case should be equal, and the holes for installing the ear rings should be at the foot of the case. The center is not deviated, the depth of the hole is appropriate, so that the watch ring is not easy to fall off; the watch mirror should be free of defects and scratches, transparent and bright; the three needles should be installed correctly, and there should be a correct safety gap between the needle and the needle, the mirror and the dial; the dial and The pointer coating has a good finish, no spots, and the dial scale lines or luminous dots are complete; there is a gap of about 0.1—0.3 mm between the handle and the case.

2. Check the sensitivity of the customized Digital sport watch
The sensitivity of a customized Digital sport watch refers to the maneuverability of its balance wheel to swing automatically. The check method is:

1) Gently shake the watch that has not been wound and has stopped, and use the shaking force to observe the movement of the second hand: if the second hand stops moving within a short time, it means that the watch is fully wound. If the second hand moves continuously for a long time, it means that the watch cannot be fully finished after winding (that is, the mainspring still stores torque), and the sensitivity is not high or The meter is malfunctioning.
2) Turn the head of the watch that has not been wound and stop moving slowly, and observe the start of the second hand: the less the winder is turned, the earlier the second hand starts, the higher the sensitivity of the watch is; otherwise, the sensitivity is low or The meter has other faults. However, it should be noted that the fast-swing watch has a higher spring speed than the traditional frequency (18000 times/hour) because of the greater stiffness of the hairspring. A watch with high sensitivity will continue to move for a longer time after a full clockwork.

3. Check the distance and position of the hands of the watch
There should be a certain distance between the hands of the watch and the watch mirror, the dial and between the three hands, otherwise they will rub against each other and affect the normal operation of the watch. It can be observed by dialing the needle during inspection. To check whether the position and coordination of the hour and minute hands are normal: set the minute and hour hands to 3 o'clock and 9 o'clock, and observe whether the two hands are at right angles; dial to 6 o'clock, and whether the two hands are in a straight line; dial to 12 o'clock, Whether the two needles overlap.

4. Check the upper body of the customized Digital sport watch
Normal watch winding should be easy. When turning the handlebar to wind up, first think it is looser, and gradually tighten it up. When the handlebar cannot be turned forward continuously, it means that the barrel is fully wound up and the winding mechanism is working normally. If there is an abnormal sound of "chattering" or the top teeth slipping when turning the crown to wind, it means that the winding mechanism is malfunctioning.

5. Check the dial mechanism of the customized Digital sport watch
A customized Digital sport watch should be mobile, reliable and even when the hands are adjusted. The inspection should focus on checking the tightness of the friction fit between the minute wheel and the center wheel shaft. When the needle is adjusted, if there is no feeling of looseness or tightness, it means that the friction of the minute wheel is normal and the oil is properly added. On the contrary, the needle setting mechanism is malfunctioning.
