USING THE CHRONOGRAPH FUNCTION
1. The chronograph can be started and stopped each time Button A is pressed.

This procedure should be performed when the chronograph second hand does not return to the zero position after the chronograph has been reset, and including after the battery has been replaced.
1. Pull the crown out to the 2nd position.
2. Press Button A to set the chronograph second hand to the zero position. The chronograph hand can be advanced rapidly by continuously pressing Button A.
3. Once the hands have been zeroed, return the crown to normal position.
*Do not push the crown to normal position while the chronograph second hand returns to zero position. It stops on the way when the crown is returned to normal position and its position is recognized as zero position.
