The power source of men's mechanical watches is a manual or automatic winding, so when the power of the mainspring is insufficient, there will be certain errors. The amount of error is within the normal range. Why do men's mechanical watches have errors? Many people are confused by this. As a manufacturer of men's mechanical watches, we are well aware of the common problems of customers, so we will share with you the related problems of error.
First of all, it is worth noting that there must be errors in mechanical watches. No matter how exquisite they are and how famous the brand is, their mechanical watches must have errors. The main reason is to see the size of the error. An error deviation is three to five Seconds are acceptable, if more than 10 seconds in such a situation occurs, you can consider fine-tuning the error. To judge the quality of a watch, its error range is also a value worth referring to. Generally speaking, the men’s mechanical watch with a smaller error range has better quality.
In 1973, the COSC Swiss official observatory testing organization began to formulate a unified standard for the accuracy of clocks and watches, but the international standard ISO3159 is a relatively broad standard. Observatory certification is much stricter on the basis of meeting ISO3159. To obtain the certificate, its movement must successfully pass the COSC (Swiss Official Observatory) accuracy test at different angles and temperatures. It takes at least 15 days to pass these tests. The average error range of the movement certified by the Observatory is between -4 seconds/day and +6 seconds/day. The specific error depends on the movement used by the watch, not according to the price. The principle is that the higher the error is, the smaller it is.
However, the error of men's mechanical watches is not only determined by the model of the movement, but also by the quality of the manufacturer. For example, the error of a general men's mechanical watch is within 15 to 30 seconds, which is currently a normal phenomenon. A mechanical watch under five minutes is already considered very good.
1. The mechanical watch travel time principle is that the mainspring powers the mechanical rotation, and the large pendulum rotates continuously to achieve automatic winding. However, the internal parts, such as the tightness of the mechanical clockwork, the wear of the movement parts, etc., cause unbalanced errors in the mechanical transmission.
2. The amount of activity of each person is different, and the amount of clockwork energy affects the travel time error.
3. Everyone has different wearing habits. For example, compared with people who sit in the office for a long time and go out for a long time, the error of their watches is also different.
