Why are we still talking about accuracy?

[home of watches]

[home] watch watch culture all the time, whether it is to buy the main table or table, or playing table friends or a problem we generally concern, is related to the accuracy of watches, although we all know that to be absolutely accurate, it is better to buy a GPS+ wave form, and real time when the atomic clock signal station, as long as no mistake, you can watch accurate. Mechanical watch because it is physical force, there is error, so we don't really care about a daily rate for a few seconds, after all, one day to walk 86400 seconds, with the error within 10 seconds, has been very precise. We often encounter such a situation, the main table spent tens or even hundreds of thousands to buy a table, there is error for several seconds but it is still a day, or even thousands of yuan and ordinary mechanical error almost, it seems to be not a justice. However, when we know all about it, we are still talking about the accuracy of all kinds of watches, and even finding fault with each other every day, hoping to be accurate to one or two seconds, so what are we talking about?

Watch how well this is a conversation

In fact, we talk about the precision of a watch to talk about a career income is how much, talking about the car can run fast, how about this restaurant taste and so on, a very common, born with the talk. For mechanical watches, its function is to tell the time, so we naturally in precision will be required of it, to some extent, watch more accurate, we can think it good quality, very high, we will be satisfied with it. Since ancient times, the mechanical clock in order to more accurate and hard, although the watch is different and they claimed to be the embodiment of art, but also must be kept in a certain range of error, only emboldened to sell a good price. Therefore, talking about the accuracy of watches, human nature, understandable.

Watch accuracy is the core of the certification standards

From the practice, any international or professional field to watch the standards must be related to the accuracy, such as the basic standard in 4800 amp antimagnetic watches, / M magnetic field, after several tests, the daily travel time error must be less than plus or minus 30 seconds, such as through the international standard ISO shockproof Watch table. Must be provided for the impact test, in addition to other types of quartz watch on the error should not exceed 60 seconds. In the past, China had regular standards for watches, and the mechanical watches were normal as long as the daily error was within 15 seconds. So you see, watch the error value itself is the important standard of each index, all need to ensure that the three aspects of the watch, one is security, one is the use of a precision, are indispensable.

In recent years, the strength of the watch factory and organization, because the modern watchmaking technology promotion, are constantly updating the standards, we are most familiar several certification, in addition to COSC, there are no major adjustments, others are more or less made some changes. COSC everyone knows that watches are required to maintain an average daily difference of -4/+6s per day after each test, but each item has corresponding precision values in the test. Rolex updated the top Observatory certification in 2015, requiring the average daily difference in -2/+2 seconds per day after the watch assembly. In 2017 Patek Philippe has the most advanced technology research of the watch, watch accuracy is improved to -1/+2s every day, and in 2009 began to use Patek Philippe imprint, requires precision is -3/+2s every day. QF certification began in 2001, requiring the movement on the basis of COSC certification, the accuracy of the entire watch to 0 to 5 seconds per day error. The mark of Geneva is that after 7 days' walking test, the measurement time of the watch is not more than one minute after 7 days. In addition to these certification, various brands have their own standards, such as the Jaeger Le Coulter 1000 hours of testing, OMEGA perfect coaxial Observatory certification, glashutte original lasu Observatory certification etc..

Precision is part of the reason why we choose a watch

When we buy a certified brand, or their own standard certification of the watch, we naturally so proud, because it represents and other ordinary watch is not the same quality, and in these standards and certification, for details of the process, function test, we may not be able to know at a glance and the precision has become a most obviously and direct certification criteria. I think a lot of table friends have such a habit, occasionally watch proofreading time, when you find a watch walk every day is very stable, worse than two or three seconds, will of course be excited about to watch quality more trust, obviously, for any one to spend money to buy their own love table the list of friends, this is a good thing.

Accuracy is often a basis for judging whether a watch is a problem or not

At the same time, what we should pay attention to is whether a watch is accurate or not. It is often a reference for us to judge whether it needs maintenance or not. The vast majority of meter testing equipment friends home and not watch the configuration, when we watch a normal wear, if you find the watch and go fast, sometimes slow, is the most direct expression of every error is very unstable, so we can judge the watch problems, need to do a test may be affected by the magnetic, because there may be a problem with the internal bump. In addition to regular maintenance without the problem of internal wear long-term wear, watch some common problems, it will be reflected in the travel time, travel time accuracy became one of the most intuitive according to whether the internal problems of the judge you watch. Although this is not absolute, but as ordinary table friends, without professional equipment, and not too many ways to know the watch is out of the question, but the speed of every 20 seconds, it should be noted, often more than half a minute on the error, should do the test.

But precision is not the basis for judging the value of watches

But we should also be clear, watch precision, in addition to the quality of their own, have a great relationship and friends daily wearing habits, we should not go to watch the daily tangle is precise to almost zero error precision. As mentioned above, as a mechanical table, table and hundreds of thousands of thousands of yuan, in accuracy may not be obvious gap, a good ETA movement after careful adjustment, can be done on the error in less than five seconds, even on the second stage of the error, and it only needs thousands of the general requirements of hundreds of thousands of yuan, not mechanical error is zero. So watch the precision, can not become the measure of a watch is a standard of value, in the modern watchmaking technology so mature environment, you can have the accurate control to a very delicate point, further tangled little significance. And watch by magnetic, or wear on some special occasions, or sports wear, will have a great impact on the travel time error, these must also be taken into account in the actual situation.

Precision is of special significance to brands

Above, I have a common table friends stand to watch precision, when I bought a new table, I will pay attention to it to go right, after all that time is the best time to remedy the problems found timely. From the brand point of view, the accuracy of the watch is a good brand image of the publicity point, the higher the accuracy, representing the more excellent level of tabulation. Rolex dare to publicly declared their top Observatory certification can watch on the error of -2/+2s per day, is through a series of simulation wear test, and the annual output of more than five hundred thousand Rolex watch, to have so many tables to achieve this accuracy, indeed shocking, and Rolex do, this is the value of it. I don't doubt that each brand can make a smaller scale express better accuracy than this, but it has greater practical significance in a very large sample size. Patek Philippe proposed -1/+2s average error is small, only 5650 in this model, a total limit of 500, I have to admit that its accuracy is the highest of all brands, beyond Rolex, but the meaning is completely different, of course, we also know that Patek Philippe and Rolex is not a market position in the game player and their pursuit of different, can not be used to arbitrary precision to measure the two brands, so I just give these two examples, the accuracy for understanding the meaning of the brand to facilitate clear.

So what are we talking about when we're talking about the accuracy of watches?

After all, watch not one time but still accurate tool, is the natural mission is watchmaker generations of tradition, throughout history, any major tabulation technology innovation, is committed to further enhance the performance of the watch, watchmakers, precision is faith. As for us, watches don't matter for a few seconds. We're talking about watches and our daily routine. (picture / text, home of Wu Yibing)
