Ago I wrote a story about why mechanical watches travel time error of the post, mechanical watches, primarily due to errors such as error and position error when, in fact, error and the size of the balance wheel has a lot of swing. I have also seen some very careful person, watch their own observations and experiments conducted, the daily travel time error also done a record, some of the mechanical watches have high accuracy requirements, in fact, a watch day with 10 seconds of error that is quite accurate, but also that is not precise enough.
Mechanical watch accuracy of travel time can not calibrated to achieve or maintain
Why? That is because the mechanical watch travel time is in constant change, the relative tightness of a winding state of a fixed position, a temperature that can temporarily accurate, but relative to another case conditions, there will be changes, immediately not the same. In other words, even if the correction is to watch one second is not bad, you find that it will not be maintained, and accuracy will always be fluctuations in the instantaneous changes. Moreover, the accuracy of the watch there are many other factors, we see that the watch can be a real error to go and the average error per unit time.
Watch full string in the spring when the best accuracy of travel time
To get accurate time his watch, it must give as much as possible on the full winding, this is more important for the automatic watch. Tighten the automatic winding watch you wear the extent and time and wear of the movement is directly related to the prerequisite is to ensure a sufficient amount of exercise.
Different locations under the watch has a different travel time accuracy
This is what we call the watch position error, the better the watch factory in under three temperatures and five directions for testing, five locations are: surface (dial up), under the surface, the next (3 below), the left (under 12:00), put on (under 9:00), only the right position (6 o'clock the next) is not used (unless you put the table into the palm of the hand or right hand side). According to statistics, most people watch in one day surface locations for 35%, and the left 30% to under 25%, 10% of other locations, so using the watch in different locations of the different travel time accuracy error , watch the speed of the trend can be corrected.
Be the first observation of the test, and then recorded
Testing is simple, need to be on the table full of winding, and then aligned by a standard test of time watch hours, minutes, seconds, so that they sync, then the first place position in the plane really take 24 hours, then the standard time than on the error and recorded. In turn repeat the process, respectively, under the watch face, the next to left, to go on the actual location of 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, to the left at +25 sec / day, put on the +10 seconds / day, results wear to go watch the actual error when the +15 sec / day.
Choose to place the watch off his watch at the position to correct the error
Take the example above, the situation, obviously, should be outstanding at hand to put down, in order to help reduce travel time watch the cumulative error. Only watch because of errors and their error characteristics of a watch accurate picture, it can better serve you.
