are screwable. to loosen the push pieces, turn them
counter-clockwise
(Figure1). the measurement starts when button a is pressed once. pressing this
button again stops the measurement. the measurement is resumed by pressing
button a once more. this allows you to add up and record the cumulative time.
Button B resets the hands of the chronograph to zero (Figure 2).
Please take care to fasten the push pieces after using the chronograph.
