SECTION 7 – USING THE SLIDE RULE BEZEL
If your watch is equipped with
a movable ring around the
watch face (as shown), it acts
as a slide rule and makes it
easy for you to calculate
speed, time, distance, and fuel
consumption, as well as doing
simple multiplication and
division, and converting among nautical miles, statute miles and
kilometers!

SETTING THE DATE ON TYPE A
There are two versions on the date setting of a Type A watch. In both
versions, the crown is first pulled out to the "MIDDLE" position.
In one version, the crown is rotated COUNTERCLOCKWISE only; in
the other version, the crown is rotated CLOCKWISE. Stop when the
desired date appears.
There are two types of Date watches. Identify the type you have from
the illustrations below, then follow the appropriate instructions for
setting.

SECTION 6 – HOW TO SET THE DATE
SETTING THE DATE ON TYPE B
Pull the crown to the "OUT" position and rotate the hands CLOCKWISE
through 24 hours until the desired date appears in the window. For a
quicker way to set the date, rotate the crown CLOCKWISE until the
date changes (approximately 1:00 am). Then rotate the crown
COUNTERCLOCKWISE back to 7:30 pm, then CLOCKWISE to 1:00
am. Repeat above procedures until the desired date appears in the
window.
Once set, the date will have to be advanced in this manner on five
occasions during the year (the five months that have fewer than 31 days).

To Set the Time:
1. Pull the crown to the "OUT" position.
NOTE: If the crown does not pull straight out, your watch is
equipped with a screw-in setting crown. Refer to Section 11 before
proceeding further.
2. Rotate the crown clockwise or counterclockwise to the desired
time.
3. Push the crown back in to restart the watch.
NOTE: To synchronize your watch with an external time reference
signal such as a clock or another watch, follow these steps:
1. When the second hand is precisely at 12 o'clock, pull the crown to
the "OUT" position. This will stop the second hand.
2. Set the watch one minute past the indicated time of the external
time reference.
3. When the time of the external time reference signal and the time set
on the watch coincide exactly (hours, minutes, seconds), push the
crown back in to restart your watch.
SECTION 5 – HOW TO SET THE DAY OF THE WEEK
There are two types of Day/Date watches. The day is set either in the
"MIDDLE" crown position or in the "OUT" position. To determine which
version you have, pull the crown to the "MIDDLE" position and slowly
rotate the crown CLOCKWISE.
If the day changes, continue to rotate the crown until you reach the
desired day. Then follow the instructions in Section 6 for setting the
date.
If the day does not change when the crown is rotated in the "MIDDLE"
position, pull the crown to the "OUT" position and proceed to slowly
rotate the crown CLOCKWISE or COUNTERCLOCKWISE through the
necessary number of 24-hour periods to advance to the desired day.
Then follow the instructions in Section 6 for setting the date.
