variations or time zone changes, adjustment is rarely, if ever,
required.
Preliminary Setting Procedure
Before the chronograph can be used, the chrono second hand
must be in the "0"(zero) or 60th second position. If not,
proceed as follows:
Step 1. Pull the crown to third position.
Step 2. Slowly push and release first button "A" until the
chrono Second in the 60th second position. If the button is
kept pressed, the hand will continue to move rapidly.
Step 3. When the hand is accurately positioned, proceed to
"Setting the Time”.

Setting The Time
Note: your watch is in normal time indication mode when the
crown is in the "first" position.
Step 1. When the small second hand reaches the 60th
second mark, pull the crown to the "third" position. All hands
will stop.
Step 2. With the crown still in the "third" position, turn it to
move hands FORWARD (clockwise) until you see the date
change. This establishes midnight.
Step 3. For AM time, continue to move 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.
SERIES 0S20
Step 4. When the time standard by which you are setting
your watch (telephone beep, etc.) reaches the 60th second,
push the crown to the "first" position without turning. All
normal hands will start moving instantly.
The series OS20 differ from OS21 by the counter of 60
seconds at 6 hour.

Setting The Date (On Some Models)
Step 1. Pull the crown out to the "second" position (one
"click"). Turn the crown counterclockwise until the desired
date appears.
Step 2. Push the crown back to the "first" position. The watch
will now be operating normally.
Note: The date will advance automatically at midnight,
provided that AM and PM have been established (see
"Setting the Time"). 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
beadvanced manually. The date should never be changed
manually between 9:00pm and 3:00am, as this might result
in an inaccurate date display. However, the mechanism will
not be damaged if the crown is turned accidentally during this
time period.

How To Use The Chronograph
Step 1. To start chronograph measurement, push and
release button "A".
Step 2. To stop chronograph measurement, push and
release button "A". Measurement ceases; time is indicated.
Step 3. To reset chronograph hands to "0", push and release
button "B".
How To Use The Tachymeter (On Some Models)
Step 1. With the watch in normal time indication mode, push
and release button "A" precisely at the start of a measured
kilometer*
Step 2. Push and release button "A" precisely at the end of
the measured kilometer.
Step 3. Read the outer edge of the dial to obtain your speed in
kilometers per hour.
Step 4. Reset your watch by pushing and releasing button
"B".
