POSITION D REFERENCE TIME SETTING
To set the reference time, unscrew the crown and then pull it out to
POSITION D .
The seconds hand is
stopped, allowing you to set the time to the precise second.
Set the reference time using the 24-hour hand that moves in increments of 30 minutes (against the
graduations on the bezel) and the minute hand (against the graduations on the dial) by turning the
crown in either direction.
Setting the reference time also moves the conventional hour hand (local time). For this reason, the ref-
erence time must be set before setting the local time.
