One, the accuracy of the mechanical watch can not be achieved or maintained by correction. Why do you say so?
Because the mechanical watch is constantly changing, in a spring state, fixed position, and temperature environment it can be temporarily accurate, relative to another situation will change.
That is to say, even if you correct your watch to the exact second, it will not stay the same, and the accuracy will always change in the instantaneous and fluctuating.
Moreover, there are many other factors that affect the accuracy of a watch.
For example, the influence of magnetism and so on.
Pass a famous doctor and friends no matter what table will soon wear half an hour, later we know, medical instruments to watch the magnetic.
The watch error we see is just the average error per unit time in real time.
Two, watch in the spring full string state when walking accuracy is best to make their own watch walking accurate, be sure to put the spring as full as possible, which is more important for automatic watches.
Because the automatic watch spring tightening degree and wear time, wear movement has a direct relationship, the premise is to ensure that there is a sufficient amount of exercise.
As for the collection of mechanical watches, some table friends think that you need to take out the chain every once in a while, go a walk;
And some other table friends that do not have to chain, because the chain is also a kind of loss.
The jury is still out.
Three, different position under the watch has different travel time accuracy, which is the so-called watch position error, better watch factory to be tested in three kinds of temperature and five directions, five positions are:
Face (dial up), face, face down (3 points down), left (12 points down), up (9 points down), only the right position (6 points down) is not commonly used (unless you bring the watch to the palm side or right hand).
According to statistics, most people in one day the position on the watch surface use time is about 35%, the left is 30%, the next is 25%, the other position 10%, so the use of the watch in different positions of different accuracy error, can correct the speed of the watch trend.
Four, first do an observation test, and then record the test method is very simple, first give the table full hair, and then use a standard time to align the test watch time, minutes, seconds, let them synchronize, first placed in the plane position after 24 hours, with the standard time comparison error and record.
Repeat the above process in turn, respectively on the watch under the face, the bottom, the left, the position of the real go error test, and recorded.
For example: the static test results are: face +20 seconds/day, face +20 seconds/day, down -5 seconds/day, left +25 seconds/day, up +10 seconds/day, then the actual wear time error of the watch is +15 seconds/day.
Five, take off the watch at night to choose the position of the watch to correct the error in the case of the above example, it is obvious that the night should be placed down the watch table (placed down the error is the minimum, -5 seconds/day), in order to help reduce the cumulative error of the watch.
Only on the watch error causes and their own watch error characteristics have an accurate understanding, it can better serve you.
