People in the purchase of watches always excellence, good and good selection. But how to choose a quality watch? In general, it is not scientific to judge the quality of a watch simply by listening to the size of the watch when it is traveling. Because the quality of the watch is good or bad, mainly to see the accuracy of the actual travel time. Watch machine issued when the sound is balanced, clear and no noise, can only explain the watch machine without failure, does not explain the quality of the watch as a way to pick the watch. You must also choose from the following points: First, check the appearance of watch parts Watch appearance from the shell, table mirror, dial and time-sharing second hand and other aspects of inspection. The case should be no trachoma and obvious scratches, edges and corners symmetry; back cover and the upper shell should be closely linked at the juncture; the two watch ring with the case of the same distance, the hole should be installed earrings in the foot of the case foot position Center not partial, the depth of the hole appropriate, so that the ring is not easy to fall off; table mirror should be free of defects and scratches, transparent and bright; three-pin installation is correct, the needle and needle, watch mirror and dial should have the correct safety clearance; Pointer coating finish, no marks, dial lines or luminous points complete; between the head and the case about 0.1-0.3mm gap. Second, check the watch's sensitivity The sensitivity of the watch refers to the flexibility of its balance pendulum. The inspection method is: 1) will not go on the clock has stopped walking watch gently shake it with the power of shaking to observe the movement of the second hand: If the second hand to stop moving in a very short period of time, then watch this watch with the clockwork After all can finish (that is, the clockwork no torque), high sensitivity; if the second hand for a long time to continue to move, then watch this watch can not all finish after the clockwork (spring also stored torque), the sensitivity is not high or Table machine is faulty. 2) will not be on the clock to stop walking watch, slowly turn the head, watch the second hand start situation: the rotation of the winding less, the second start of the watch the higher the sensitivity of the table; the other hand, the sensitivity is low or Table machine has other problems. However, we must pay attention to Swift Watch swinging gossamer due to the greater stiffness than the traditional frequency (18,000 times / hour) watch a little more winding machine can swing. Sensitivity of the watch, on the foot of a winding longer after moving around. Third, check the watch pointer spacing and location Needle and table mirror, between the dial and between the three need to maintain a certain distance, or scratch each other and affect the normal operation of the table. Inspection can be observed by dial needle. The hour and minute hand position and mutual cooperation is normal inspection method is: the minute hand and the hour hand dial 3 o'clock, 9 o'clock, observe whether the two needles at right angles; dial to 6 o'clock, two needles into a straight line; dial 12 o'clock, Whether the two coincide needle. Fourth, check the watch above the body Normal watch winding should be relaxed. Turn the head on the article, the first feel loose, gradually more and more tight, when you can not continue to turn the head forward, that the clockwork has been completely full and the body work properly. If you turn the handle on the article, the occurrence of "chattering abnormal sound, or produce top tooth slippage and other phenomena, then the body is a failure. Fifth, check the watch dial needle agencies The watch should be flexible, reliable and the pointer is rotated evenly. Inspection should focus on checking the sub - round friction with the center axle with the tightness. In the allocation of needle, if there is no partial loose or tight feeling, that the normal friction wheel and the amount of fuel, on the contrary, needle machine fault.
