How do I use Pioneer chronograph?

How to Use the Chronograph (Measuring Accumulated Time)

Start by pressing the push-button A. Notice that the chronograph has begun measuring time, as the red-tipped hand in the dial begins to move clockwise. To stop the chronograph from measuring, press the push-button A. Read the recorded minutes in the left subdial. The Pioneer’s second-hand records the seconds. 

Let’s say you want to resume measuring the time where you left off. Just press the push-button A, and the time will resume. To stop measuring time, press the push-button A, and the final time is displayed in your dial and subdials. 

Once you’re done with measuring the accumulated time, reset your chronograph by pressing the push-button B. The Pioneer’s hands will be reset to their zero position. 

At last, you can finally use all of the functions of your new Pioneer! There’s just one more thing. Often when our watches arrive at their new home, the chronos second-hand, indicated by its red tip, isn’t positioned on the natural zero position, 12. Repositioning the chronos second-hand is simple to remedy and is due to a functions test during your watch’s production to ensure that your Pioneer watch properly functions.  

To align the zero position of the chronos second-hand, pull the crown to the second position. Press button A until the chronos second-hand has aligned to the natural zero position, which is at 12 on your dial. Push in the crown, and the watch resumes functioning.
