How To Set The Time And Date - Seiko 8R46 Instructions Manual

* If the watch is used without being wound up fully, gain or loss of time may result. To avoid this, wear the watch for
1
more than 10 hours a day. If the watch is used without being worn on the wrist, be sure to wind it up fully every day
at a fixed time.
* If you use a watch that has stopped with the mainspring unwound, winding the mainspring with the crown will not
start the watch immediately. That is because the mainspring torque or force is low at the beginning of its winding
due to the characteristics of mechanical watches. The small seconds hand will start to move when a certain degree
of torque is reached after the mainspring has been wound up. However, swinging the watch from side to side to
forcibly turn the balance can start the watch sooner.

How to set the time and date

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.
b CAUTION
Do not amend the date when the watch is displaying between 8 PM and 2 AM.
Amending the date during this time period may cause problems such as the date failing
to change the next day.
