Maintain mechanical watches travel time accuracy

Mechanical watch travel time accuracy can not be achieved through the correction or to maintain.
Mechanical wrist watch travel time accuracy can not be reached or maintained by calibration Why? That is because the mechanical watch travel time is constantly changing, relative to a state of elastic spring, a fixed position, a temperature it can be temporarily accurate , But with respect to the other conditions, there will be changes, immediately different.

In other words, even if the watch calibration is not bad for a second, you find it will not be maintained, the accuracy will always change in the instantaneous and volatile. Moreover, the accuracy of the watch there are many other factors, we see the watch error can only be a real go and the average error per unit of time.

Wrist watch winding state when the best accuracy when you want to go their own watch accurate time, we must make full winding as possible, this is more important for automatic watches. Because the winding of the automatic watch is tightened to a degree that is directly related to the time you wear and the movement you wear, the premise is to ensure that there is a sufficient amount of exercise.

Different locations have different watch travel time accuracy This is what we call the watch position error, better watch factory to test at three temperatures and five orientations, the five positions are: surface (dial up (Under 3), left (under 12), upper (under 9) only the right position (under 6) is not commonly used (unless you bring the watchband to the palm of your hand One side or right hand). According to statistics, most people use the time on the surface of the watch for about 35% of the time in a day, the left is 30%, the next is 25% and the other positions are 10%. Therefore, different accuracy errors when using the watch in different positions , You can correct the watch's trend.

First to observe and test, and then record the test method is very simple, you need to give a watch full of clockwork, and then a standard time to align the watch being tested, minutes, seconds, so that they are synchronized, and then placed in the plane position After 24 hours, go through the standard time and record the error. Repeat the above process in turn, respectively, under the watch surface, the next, the left, put the actual position on the error test, and recorded.

For example: static test results are: the surface of +20 seconds / day, under the surface of +20 seconds / day, the next -5 seconds / day, the left +25 seconds / day, the +10 seconds / day, the results The actual error when the watch is worn is +15 seconds / day.

Take off your watch at night Select the orientation of the watch to correct the error Take the example above, it is clear that the watch should be placed down at night to help reduce the cumulative error when walking watch. Only the reasons for the error of the watch and watch their own error characteristics have an accurate understanding of it can better serve you.
