Welcome to patronize!     Shenzhen Luohu District Time Record Watch Wholesale Trading Firm Contact Person: Mr. Wei Runteng (Marketing Department, Manager)   Address: Shenzhen, Guangdong, China   Check the appearance parts of the watch The appearance of the watch can be checked from the case, mirror, dial and hour and second hand. The case should be free of trachoma and obvious scratches, with symmetrical edges and corners; the back cover and the upper case should be tightly screwed; the distance between the two watch rings and the case should be equal, and the hole for installing the ear ring should be centered at the tail of the case foot. 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 are installed correctly, and there should be a correct safety gap between the needle and the needle, the watch mirror and the dial; the dial and the hands are coated with good finish, no spots, and the dial scale lines or luminous spots are complete; there is a gap of about 0.1-0.3mm between the head and the case ...  Second, check the sensitivity of the watch The sensitivity of a watch refers to the flexibility of its balance wheel to swing automatically. The inspection method is: 1) Gently shake the watch that has not been wound and has stopped moving, and use the shaking force to observe the movement of the second hand: if the second hand stops moving in a very short time, it means that the watch can be fully wound (that is, the clockwork has no torque), and the sensitivity is high; if the second hand continues to move for a long time, it means that the watch cannot be fully wound (that is, the clockwork also stores torque), the sensitivity is not high or the watch machine is faulty. 2) Slowly turn the handle of the watch that has not been wound up and stopped moving, and observe the starting situation of the second hand: the less the rotation of the upper handle, the earlier the second hand starts, the higher the sensitivity of the watch; otherwise, the sensitivity is low or the watch machine has other faults. However, it should be noted that the fast pendulum watch needs a little more clockwork to swing than the traditional frequency (18,000 times/hour) due to the large stiffness of the hairspring. Watches with high sensitivity continue to move for a long time after being fully wound. Third, check the spacing and position of the watch hands There should be a certain distance between the hands and the watch mirror, between the dial and between the three hands, otherwise they will collide with each other and affect the normal operation of the watch machine. When checking, you can observe by dialing the hands. The check method for the position and mutual cooperation of the hour and minute hands is: dial the minute and hour hands to 3 o'clock and 9 o'clock to observe whether the two hands are at a right angle; dial to 6 o'clock, whether the two hands are in a straight line; dial to 12 o'clock, whether the two hands coincide. Fourth, check the mechanism on the watch A normal watch should be easy to wind up. When turning the handle on the bar, it feels looser at first, and gradually gets tighter and tighter. When the handle cannot be rotated forward, it means that the clockwork is completely full and the upper mechanism is working normally. If there is an abnormal sound of "chirping" when turning the handle on the bar, or the top tooth slips, it means that the upper mechanism is faulty. Check the watch dial mechanism When dialing the needle, the watch should be flexible, reliable and the hands should rotate evenly. When checking, focus on checking the tightness of the friction fit between the wheel and the center wheel shaft. When dialing the needle, if there is no feeling of looseness or tightness, it means that the friction force of the wheel is normal and the amount of refueling is appropriate. On the contrary, the dialing machine is faulty.
