SETTING NON-DATE MODELS
If the watch has no second hand,
IN POSITION merely pull out the crown and proceed
to step 2.
Step 1: When the second hand rea-
ches the 60th second mark, pull the
crown to the "OUT" position. All hands
will stop.
OUT POSITION
Step 2: Turn the hands forward (cloc-
kwise) to set the time. In order to prevent the hands from
jumping when the crown is pushed in, set the minute hand
approximately 5 minutes ahead of the desired minute marker;
then, gently turn back to the same minute marker.
Step 3: When the time standard by which you are setting your
watch reaches the 60th second, push the crown to the "IN"
position without turning. All hands will start instantly
SETTING DATE AND DAY/DATE MODELS

midnight.
Step 3: For AM time, continue to move
the hands forward until the minute hand is approximately 5 minutes
ahead of the desired minute marker; then, gently turn back to the
same minute marker. For PM time, follow the same procedure, but
first advance the hands past 12 o'clock.
NOTe: The date will advance automatically at midnight, provided
that AM and PM have been established (steps 2 and 3). The watch
calendar is programmed for a 31-day cycle. Therefore, on the first
day of any month following a month with less than 31 days, the date
must be advanced manually (see Step 5).
Step 4: When the time standard by which you are setting your
watch reaches the 60th second, push the crown all the way to the
"IN" position without turning. All hands will start instantly.
Step 5: Pull the crown to the "INTeRMeDIATe" position (one
"click"). Your watch will continue to tell time. Slowly turn crown one
way until correct date appears. Then, for day/date models, slowly
turn crown the other way until correct day appears.
NOTe: The day is printed in two successive positions on the day
indicator: in english and in Spanish on U.S. models; in english and
in French, depending on the models. It is possible to make use of
either position. The display will automatically remain in the language
chosen. In some models, the calendar cannot be changed manu-
ally between 9:00pm and 6:00am. However, the mechanism will not
be damaged if the crown is turned accidentally during this period of
time.
Step 6: Push the crown to the "IN" position. Your watch is now
operating normally.
HOW TO USE THE ELAPSED TIME INDICATOR
If your watch is equipped with a rotatable
outer dial with oneminute graduations,
this can be used in various ways to check
elapsed time. For example if a diver has a
30-minute air supply, he can set the outer

ring so that the triangle is in line with the minute hand when
he submerges. The minute hand will then indicate on the
outer ring the length of time that the diver has been under
water.
SCREW-DOWN CROWN
If your watch includes a screw-down crown, you have ad-
ditional assurance that it will remain watertight. To make the
crown operational, it must be turned toward you until the
threads are disengaged. Then, instructions for setting must
be followed. To reseal the crown, press in until threads en-
gage. Turn away from you until tight.
IMPORTANT: Unless the crown is properly resealed, it
will not be watertight.
IF YOUR NEW WATCH IS A MECHANICAL WATCH

Mechanical watches differ from Quartz watches in several
respects:
1. No battery changes are needed - they are powered by a

it.After that, your daily activity should wind the watch suffi-
ciently to keep it running at night when it is not being worn. If
your normal daily activity is not sufficient, occasional sup-

that your mechanical watch be cleaned and oiled periodically
to insure optimum performance. As a mechanical watch,
