Perpetual calendar display is not accurate.

Generally, due to power failure, voltage instability, long use time and other reasons, it will cause inaccurate travel. If you are not allowed to leave, you can make adjustments.

Methods: The perpetual calendar regulator has four buttons, namely exit, run (downward adjustment), upward adjustment and setting.

First, press the "Set" button (enter the time setting state, the year flashes), and you can press the "Up" or "Down" button to modify the year. After modification, press the "Set" button to switch the flashing to the Gregorian calendar month, and press the "Up" or "Down" button to modify the month: you can adjust the date in the same way.

Secondly, press "Set" or "Exit" to exit the time setting and return to the normal time state.
