BEFORE USING THIS WATCH
STOPWATCH HAND ADJUSTMENT
1. Refer to the diagram. Notice the small dial on the bottom and
the small dial on the left side. These are the stopwatch hands.
The bottom dial shows elapsed seconds (0-60) and the dial on
the left shows elapsed minutes (0-60). These hands are synchro-
nized with each other. They must be programmed to start at the
"zero" or 12 o'clock position before the stopwatch can be used.
2. Pull the crown to the position "3". Push and hold buttons "A"
and "B" simultaneously for two seconds, then release. The stop-
watch second hand (bottom small dial) will move backwards for
one half turn and then forward for one half turn. This will elec-
tronically reset
3. With the crown still in position "3", push either button A or B to
position the stopwatch second hand. Button "A" will move the
hand backwards (counter-clockwise). Button "B" will move the
hand forward (clockwise). Each push of the buttons will move
the hand one step — if the button is held "in" the hand will
move rapidly.
4. Remember, the stopwatch second and minute hands are syn-
chronized with each other. For each revolution of the second
hand, the minute hand will move one minute. Both hands must
be positioned at the zero or 12 o'clock position.
SETTING THE TIME
With the crown still in position "3", turn the crown to set the
hands to the desired time. We suggest moving the hands to approx-
imately 5 minutes past the correct time — then backwards to the
STOPWATCH VD53/54
correct time. The 24 hour hand is permanently synchronized with
the hour/minute hands. When setting the hands, check the 24 hour
dial (on the right side of the watch — see diagram). AM time is
0-12 Hours on this dial, PM time is 13-24 hours on this dial (24:00
hours is midnight). After the time is set, push the crown back to
position "1".
SETTING THE DATE
1. Pull the crown to position "2" (See diagram).The watch will
continue to run. Turn the crown away from you to advance to
the current date.
2. Once the date is set, push the crown back to position "1".
Note: Do Not set the date as above between the hours of 9:00 pm
and 1:00 am. This may cause the date to be incorrect and the date
will have to be reset later.
USING THE STOPWATCH/ SPLIT TIME
1. Insure that the stopwatch hands have been properly adjusted
(see section "Before Using This Watch", above).
2. Push the "A" button to start the stopwatch. Push "A" button
again to stop.
3. Push the "B" button and the stopwatch hands will automatically
return to the "0" or starting position.
4. For "SPLIT" time measurement — With the stopwatch running,
push button "B". The hands will stop moving, but the watch
will keep the stopwatch time internally. Push "B" again and the
hands will catch up to the actual elapsed time.
ELECTRONIC RESET FOR STOPWATCH
If for any reason, the stopwatch behaves erratically, it can be elec-
tronically reset as follows:
1. Pull the crown to position "3".
2. Push buttons "A" and "B" simultaneously for two seconds, then
release.
3. The stopwatch second hand will move backwards for 1/2 revo-
lution then forward 1/2 revolution.
4. Reset the hands to "0" following the above instruction:
"Stopwatch Hand Adjustment", steps #2 through #4.
5. Push the crown back in.
