The watch is convenient for timing and can play a decorative role. So it is our life very like to wear! However, the use of long time will inevitably appear wear and tear. So what about watch wear? The following watch home to tell you!
1, the most important core of a watch is the movement, even if it is a second-hand watch or antique watch, if its movement is strong, it is not less than a new watch. However, the watch as a small precision mechanical timing device, long-term use caused by wear is also very large.
2, the wear parts of the watch are generally concentrated on the needle chord, the most typical is that the shaft eye of the splint is worn off, the ground quanx, the eye hole of the shaft is elliptical, so that once wound up, the wheel will be tilted due to the force, resulting in changes in the mesh of the gear, serious will not go well, and even the phenomenon of stopping when walking. Therefore, regular maintenance of the needle chord has become a compulsory course for professional households.
3, early watches, generally in the main splint center hole are not drilled, and the center hole is the most easily worn part, to the dial as a reference object, if you carefully observe the watch minute hand, it will be found that when the needle, the minute hand in a rotation of the needle tip will be obviously high in a certain position, in another position with 180 degrees low, When it is high, it may rub against the second hand, and when it is low, it may rub against the disk, which means that the center hole of the main splint is worn off. This problem needs to be repaired with a punch to squeeze the splint in order to repair.
4, back to the previous problem, when people are winding and picking the needle, the winding can not appear gear slip and make a strange sound, the needle must be smooth, not obviously too tight and too loose, or tight and loose. There are repeated push and pull the table handle, the table handle should have a sense of gear, the old watch is very easy to break the positioning rod of the cover spring.
5, slightly use a bit of force to put the table, the table should not be easily put out, the old watch’s movement lying wheel, vertical wheel oblique teeth wear more, pull the tail hook is particularly prone to problems, and now there are basically no accessories to replace, repair is very difficult. Of course, the new watch has no such trouble.
6, in addition, the rest of the check needs to open the back cover of the watch, friends also have a certain amount of professional knowledge. The quality of the movement is very important, and watches with obvious repair traces everywhere are not to be wanted. The strap can be given to some specialized watch master with machine polishing, the dial next to polishing at least two or three hundred, so the need to polish friends to see the value of the watch itself is not worth it.
