Notes

 The stopwatch second hand wil  continue moving until you stop it. Be sure 

 

to stop and reset the stopwatch after you are finished using it. Leaving the 

stopwatch running will run down the watch’s battery.

Adjusting the Stopwatch Second Position
Use of the stopwatch can cause the starting positions of the stopwatch minute 

hand and second hand to become misaligned. Use the following procedure to 

check hand alignment and to adjust the positions of the hands so they point to 

12 o’clock when the stopwatch is reset.
To adjust the positions of the stopwatch hands

 Press 

1. 

B

 to reset the stopwatch, and check the alignment of the stopwatch 

minute hand and second hand.

 Pull out the crown to the second click.

2. 

 Press 

3. 

A

 to move the stopwatch second hand forward until it points to 

12 o’clock.

 If the stopwatch minute hand is aligned correctly, proceed to step 5. If the 

4. 

stopwatch minute hand is also misaligned, press B so the stopwatch minute 

hand jumps to

position

 Note that pulling the crown out also stops hour and minute hands. After 

 

performing the above procedure, you should also adjust the timekeeping setting.

For a watch with an elapsed time bezel

 

Rotate the elapsed time bezel to align the 

 mark with the 

minute hand.

After that, you wil  be able to determine how much time has 

elapsed since you adjusted the bezel position by checking the 

bezel value that the minute hand is currently pointing to.

Elapsed time bezel

 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.

 Note that a screw lock crown watch is not water resistant 

 

while its crown is loose. Be sure to screw the crown back in 

as far as it will go after configuring settings.
