Themis NH35A User manual

Movement Manual
ACCURACY:
In the technical documentation, Time Module claims that the NH35A accuracy range is
within -20~+40 seconds per day under normal conditions. They recorded these accuracy
measurements without the date complication being active. This shouldn’t have any
noticeable bearing on the accuracy, but it’s interesting nonetheless.
Note: When you attempt to get a measurement of your watch’s accuracy, it’s important to
make sure your watch is fully wound or the lack of power reserve may skew the test results.
TMI states that measurements should be done within 10-60 minutes after the movement is
fully wound up.
WINDING THE MAINSPRING:
So what does fully wound up mean? The NH35A should be fully wound after about 55
manual turns of the crown.
This movement is also equipped with the Seiko Magic Lever, so shaking the watch side to
side should get it going almost immediately.

CROWN POSITION FUNCTIONS:
0 (against the case): Clockwise= Manual Winding / Counterclockwise = Nothing
1 (pulled out one click): Clockwise= nothing / Counterclockwise = Date setting
2 (pulled out two clicks): Time setting clockwise and counterclockwise
NOTES ON CALENDER SETTING:
1. Do not change the Calendar between 9.00 PM and 4.00 AM, as it may not change
properly. If it is necessary to set the Calendar during that time period, first change the time
to any outside those hours, set the calendar then reset the correct time.
2. When the day shifts automatically to the next day, the other language will temporarily
appear.
3. When setting the hour hand, check that AM/PM is correctly set. The watch is so designed
that the calendar changes once every 24 hours.
Turn the hands last the 12 o’clock marker to determine whether the time is set for the A.M.
or P.M. period. If the calendar changes, the time set for the A.M. period. If it does not
change, the time is set for the P.M. period.
