Compared with other watches, the function of the perpetual calendar is not only complex, but also very troublesome to adjust. Of course, if you wear it every day and the movement is running constantly, then there is no need to adjust it. However, if you put it down and let the movement stop for a few days, it is very troublesome to adjust it, because each display is linked, so it is easy to jam the movement if it is improperly adjusted.

It is not possible to adjust the calendar during the period from 22 o ‘clock every day to 2 o ‘clock the next morning, because this period is the time when the gear that displays the calendar has been fully snapped and is slowly working. Different brands may have longer taboo time, which needs to refer to the manual. Can not be adjusted between the 26th of the month to the 2nd of the next month, then the adjustment movement must be stuck.

Almost all perpetual calendar functions are forbidden to call back, that is, if you adjust for a day, you need to stop the movement for a day.

Therefore, the best way to maintain the function of the perpetual calendar is to ensure that the movement works properly and is never adjusted. The safest way is to buy an “automatic winding box”, so that when the watch is not worn, it can also wind the movement to prevent stagnation.

In fact, the perpetual calendar is not all good, on the contrary, this is a very sentimental function. Just imagine, in the face of such a complicated calendar, the watchmaking master is with what kind of determination, studying heaven and earth, to achieve all the changes in this function. As the owner of a perpetual calendar watch, thinking of these, it must not be difficult to understand the mood of “the dead are like Sifu, not willing to sacrifice day and night”.
