How to set the time and date (6R55)

The watch is provided with a date function and is so designed that the date changes once every 24 hours.

The date changes around 12 o’clock midnight. If AM/PM is not properly set, the date will change at 12 o’clock noon.

To adjust the date only on a day such as the next day after the completion of a month that has less than 31 days (February, April, June, September and November), please refer to Date adjustment at the end of the month.

CAUTION

Do not set the date between 9:00 p.m. and 1:00 a.m.
Amending the date during this time period may cause problems such as the date failing to change the next day.

  2. To carry out the procedure, please make sure that the watch is in a working state. Please wind the mainspring when the watch is not working.
