After 24 hours have elapsed, the date will also change on the clock.
However, if you have a mechanical watch or want to cross months, you may need to change it manually.
At times like that, for your watch“Do not change during this time!” time period"Date change prohibited time period"There is such a thing!
■What is the period when date changes are prohibited?

It's not very well known, but it's actually very important.
The calendar feed wheel is in mesh with the calendar between 8pm and 4am.
This period is called the date change prohibition period, and if the date is changed by operating the crown during this period, the force of moving the calendar will be doubled, which may cause damage to parts and damage.
■It's okay now♪Correct way to change the date
