How to adjust the week and calendar of the mechanical schedule? What are the considerations?

1. Unable to adjust the week and calendar from 21pm to 3am, which is very harmful to the watch. Calendars are the pulsation of driven gears, often running gently.

2. There is a difference between a mechanical watch and a quartz watch. The dates and weeks of a quartz watch both have zero point jumps, and this accuracy is only available in electronic watches. The pointer of a mechanical watch is not very accurate and may be advanced or delayed, which is why dates and weeks are pushed in circles.

If jumping at the same time, the requirements for the driver are very high. So it should be changed separately. Generally speaking, the week will change after the date is skipped for half to a few hours. 

4. If you encounter dates on your watch at 11pm, 12pm, and 1pm, jump. Don't worry, just turn the clock clockwise once and readjust the date.

5. The middle of the two is the adjustment knob, the first is to adjust the date, and the second is to adjust the time. First adjust the gear, then rotate to adjust the date, and then rotate to adjust the week. If the week is not displayed, there is no need to set it.
