• Some water resistant models are equipped with a
screw lock crown.
• With such models, you must unscrew the crown in the
direction noted in the illustration to loosen it before
you can pull it out. Do not pull too forcibly on such
crowns.
• Also note that such watches are not water resistant
while their crowns are loosened. Be sure to screw the

hand to the timekeeping seconds hand (indicating the current seconds count), press
B again. This will enter the Timekeeping Mode.
Notes:
• Do not try to perform stopwatch operations while the crown is pulled out either to the
first or second click. If you try to press a button, you might accidentally cause the
crown to rotate and change the current time or day setting.
• If the starting positions of the stopwatch second hand and 1/20 second hand
become misaligned, use the following procedures to adjust the position of the
stopwatch second hand so it points to 12 o’clock and the 1/20 second hand so it
points to .0 when the stopwatch is reset.
To adjust the positions of the stopwatch hands
1. Press B to reset the stopwatch, and check the alignment of the stopwatch second
hand and 1/20 second hand.
2. Pull out the crown to the second click.
3. Press A to move the stopwatch second hand.
4. If the stopwatch 1/20 second hand is aligned correctly, proceed to step 5. If the
stopwatch 1/20 second hand is also misaligned, press B to move the stopwatch
1/20 second hand.
5. After making the adjustments you want, push the crown back in to its normal
position.
• Note that pulling the crown out also stops the timekeeping second hand. After
performing the above procedure, you should also adjust the timekeeping setting.
