The small bottom dial is seconds counter and there is no option to set or reset it as it is part of the main gear train - it just counts the seconds. Top right dial is 1/10 seconds counter and runs only when the chronograph function is engaged. One full circle indicates 1 second. Top left dial is 30 minutes counter and runs only when the chronograph function is engaged. One full circle indicates 30 minutes, two circles = 1 hour. The big centre seconds hand is actually Chronograph hand and runs only when the chrono function is engaged. So, the chronograph hand and two top dials works all together when chrono function is engaged. To start chrono: push upper button once. To stop chrono: push upper button again (once). To return all hands to zero: push lower button once. There is another option: if you already stopped chrono by pushing upper button, but want to continue counting without returning hands to zero, push the upper button once more and the counting will start from the point where it stopped. You can repeat this as many as you wish - it will count on and on, till you will stop it and reset to zero. Fine tuning of chrono hands can be made by pulling the crown half way out and while leaving in this position pushing and holding one of the push buttons (which one - depends on movement caliber). Watch has an tachymeter function as well (big inner ring). Learn how to use it by browsing through my Tips and Tricks- it is explained there. Rate me, please.

Pull out the stem to the second position then push the chronograph start/stop button a few times to move the minute hand to the zero position. Then pull the stem out to the 3rd position and adjust the second hand again by pushing the start/stop (top) button to move it to the zero position. Once you get them both to top zero push the stem back all the way and screw it in tight. Tim

Hi, I had the same problem and was able to fix it by reading the manual:

Basic Settings for the chronograph hand -
After changing the battery, or in exceptional circumstances, following incorrect operation, it is necessary to reset the Chrono indicator to zero (starting time).
- Leave the winder in Position 1 (pushed all the way in)
- Press button H (top) and button I (bottom) at the same time
- Now set the 30 minute (small hand) counter to zero by pressing/holding button I (bottom button)
- You can now set the 60 second counter to zero by pressing/holding button H (top button).

This worked for me... it took me a while to figure it out, but that

go to the citizen web site (citizen.com) and select "technical support" and then "setting instructions".

Enter the number off the back of your watch snd the click on "get setting instructions"

The instructions include the steps you need to take to zero the hands.

Do as follows:
1) pull out crown and set the hour and minute hands at 6 o'clock (they must be lined perfectly in opposite directions)
2) push the crown in half way back (not completely)
3) push and hold the button at 2 o'clock (set the big seconds hand to zero) and release it when done
4) when big seconds hand is zeroed push the crown back in
5) pull the crown out again and set desired time
6) push the crown back in.
If all actions described do not work, you will have to visit your nearest watch repair shop and ask to refit chronograph hand as in this case it is out of balance (not pointed at exact mark).

When you reset the big seconds hand to zero, the hour and the minute hand are not engaged in this function, so, there is no fault with the watch movement.

Try setting the crown to position 2 - i.e. the position normally used to adjust the date.  Then use the top and bottom stopwatch buttons to adjust the minute hand and 1/10th hand respectively.

for my victorinox, the crown out one position and the reset button (lower chronograph button) changes the minute hand and the top (start/stop button) does the 10th's of a second...crown all the way out and top (start/stop button) does 30 second intervals for the minute counter.
