Check the appearance and parts of the watch The appearance of the watch can be checked from the case, glass, dial, and hour, minute, and second hands.The watch case should have no pinholes or obvious scratches, with symmetrical edges and corners; the junction between the back cover and the top case should be tight; both watch rings should be equidistant from the case; the holes for installing the ear studs should be centered at the end of the case without deviation; the depth of the holes should be appropriate to prevent the watch rings from falling off; the watch glass should have no blemishes or scratches, transparent and shiny; the three hands should be installed correctly with proper safety gaps between hands, glass, and dial; the dial and hands coating should be smooth without spots; the dial scale lines or luminous points should be complete; there should be a gap of about 0.1-0.3mm between the crown and the case. 2. Check the sensitivity of the watch The sensitivity of a watch refers to its balance wheel's flexibility in automatically starting.The inspection method is: 1. Gently shake a watch that has not been wound and has stopped moving. Use the shaking force to observe how the second hand moves: If the second hand stops moving in a very short time, it means that the watch cannot fully wind up after being fully wound and has no torque; if the second hand continues to move for a long time, it means that the watch cannot fully wind up after being fully wound and still has torque stored; if the sensitivity is not high or there is a fault in the watch mechanism. 2. For a watch that has not been wound before and has stopped moving, slowly turn the crown and observe how the second hand starts moving: the less the crown is turned, the sooner the second hand starts moving, indicating that the watch has higher sensitivity; otherwise, it means the sensitivity is low or there are other faults in the watch mechanism.However, please note that due to the higher stiffness of the hairspring, a watch with a fast oscillation rate requires a bit more winding than traditional watches with a frequency of 18,000 times/hour.A highly sensitive watch that keeps running for a long time after fully winding. 3. Check the spacing and position of the watch hands There should be a certain distance between the watch hands, watch glass, watch face, and between the three hands, otherwise they might collide and affect the normal operation of the watch mechanism.During inspection, you can observe through the dial needle.The method to check if the positions and coordination of the hour and minute hands are normal is as follows: set the minute and hour hands to 3 o'clock and 9 o'clock, observe if they form a right angle; set them to 6 o'clock, observe if they form a straight line; set them to 12 o'clock, observe if they overlap. 4. Check the watch's winding mechanism Winding a normal watch should be effortless.When winding the handle, it initially feels loose but gradually tightens as you wind it. When you can't continue to turn the handle, it means the spring is fully wound and the winding mechanism is working properly.If there is an abnormal squeaking sound when winding the handle or issues like teeth sticking or slipping occur, it indicates a malfunction in the winding mechanism. 5. Check the watch's dial mechanism The watch should move smoothly and reliably when adjusting the hands, with even pointer rotation. During inspection, focus on checking the tightness of the friction fit between the dividing wheel and the central wheel shaft. When adjusting the needle, if there is no feeling of being too loose or too tight This indicates that the friction force of the wheels is normal and the oiling is appropriate; otherwise, there is a malfunction in the needle-moving mechanism.
