Using the Stopwatch  
The stopwatch lets you measure elapsed time up to 4 hours, 59 minutes,  
59 seconds.  
The illustration shows a time of 2 hours, 20 minutes, 40 seconds.  
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.  
When an elapsed time measurement reaches five hours, the stopwatch hour  
hand will stop but the stopwatch minute and second hands will continue to  
move.  
To measure elapsed time  
1. Press A to start the stopwatch.  
2. Press A to stop the stopwatch.  
You can resume the measurement operation by pressing A again.  
3. Press B to reset the stopwatch.  
Adjusting the Stopwatch Hands Position  
Use of the stopwatch can cause the starting positions of the stopwatch hour  
hand, minute hand and second hand to become misaligned. Use the following  
procedures 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  
1. Press B to reset the stopwatch, and check the alignment of the stopwatch  
hour hand, minute hand and second hand.  
2. Pull out the crown to the second click.  
3. Press A to move the stopwatch second hand forward until it points to  
12 o’clock.  
4. If the stopwatch minute hand is aligned correctly, proceed to step 5. If the  
stopwatch hour hand and stopwatch minute hand are also misaligned, press B  
so the stopwatch hour hand and the stopwatch minute hand jump to 0 (60).  
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.
