How to choose a satisfactory watch
Generally, people only use the sound and height of the watch machine to judge the quality of the watch, which is unscientific.Because of the quality of the watch, it mainly depends on the accuracy of its actual time.The sound, clearness, and no sound made by the watch machine can only indicate that there is no failure of the watch machine, and it cannot indicate the quality of the watch as a way to select the watch.
You must also choose from the following points:
1. Check the appearance parts of the watch
The appearance of the watch can be checked from the aspects of the shell, the mirror, the dial, and the hourly second hand.The case should have no sand eye and obvious scratch, and the angular and symmetrical; the rear cover and the rotor of the upper shell should be tight; the distance between the two rings is equal to the case.In the middle of the middle, the depth of the hole is appropriate, making the ring not easy to fall off; the surface of the mirror should have no defects and scratches, transparent and bright; the three stitches are correct, and there should be a correct safety gap between the needle and the shingle, the mirror and the dial; the dial and the dial and the dial;The pointer is plated with good smoothness, no spots, and the dial scales line or night light is complete; there is about 0.1-0.3mm between the head and the case.
2. Check the sensitivity of the watch
The sensitivity of the watch refers to the flexibility of its swing automatically.The check method is:
1) Shake the watches that have not been on the clockwork, and use the power of shaking to observe the situation of the second hand: if the second hand stops walking in a short time, it means that the watch is on the watch.后能全部走完(即发条无力矩)，灵敏度高;如果秒针长时间继续走动，则说明这只手表上足发条后不能全部走完(即发条还储存力矩)，灵敏度不高或There are faults.
2) The watches that have not been stopped on the hair stick, slowly rotate the head, observe the start of the second point: the less the upper handle, the earlier the second needle, the higher the sensitivity of the watch; otherwiseThere are other faults.However, it should be noted that the fast -to -watch watch is more rigid than the traditional frequency (18,000 times/hour) of the watch.The high -sensitivity watch continues to move for a long time after a stump.
3. Check the distance and location of the watch pointer
Between the acupuncture, between the mirror, the dial, and the three stitches, it should be kept a certain distance, otherwise it will cause the touch of each other to affect the normal operation of the machine.Observations can be observed during inspection.The position and the normal check method of the timing of the chronth cue and the clockwise is: dial the minute hand and the time clockwise to 3 and 9 oclock, and observe whether the two needles are in right angles;Whether two stitches are over.
Fourth, check the entrance institution on the watch
Normal watches should be relaxed.When turning the top of the head, it feels more loose first, and gradually becomes tighter and tighter. When you cant continue to rotate your head forward, it means that the clockwork has been fully full and the upper -bar institution is working normally.If the phenomenon of "tagging abnormal sounds, or slipping of top teeth when rotating the head of the handle, it means that there is a failure of the upper barrier.
5. Check the watch dialing institution
The watch should be flexible, reliable and pointer evenly when dialing the needle.During the inspection, the tightness of the coordination of the division and the central wheel axis should be reviewed.When dialing the needle, if there is no loose or tight feeling, it means that the rubber rubbing force is normal and the amount of refueling. On the contrary, there is a failure of the needle parts.
