How do I reset the chronograph? Once I start it I can't find a way to reset it.

This watch appears to be a battery operated model from the details I can find. Self Winding watches tend to be a LOT more expensive and usually a Big brand name! Assuming the Chronograph is designed to work the two buttons are usually 'Start/Stop', (top button) and 'Reset', (bottom button). Try this.

-Press the top button once. The smaller dials should start moving.
-Press the top button again. The smaller dials should stop moving.
-Press the bottom button once. The dials should reset to zero. There is another function of the Reset button. You can 'Freeze' the chronograph display for things like lap times.

-Start the chronograph, (Top button once).
-Press the Reset button once, (Bottom button). The dials should stop. The chronograph is still running you have simply paused the display.
-Press the Reset button again. The dials should 'Jump' to the current position the timer is at.
-Press the Top button once to stop the chronograph. *Note* Some of the cheaper watches simply have the dials and buttons for the look of it and don't actually work.

This is a chronograph watch. The top button starts the second hand (the chronograph) the bottom button resets the chronograph to zero. You need to first press the top button to start and the press the top button again to stop. then press the bottom button to reset. The hands will not reset if you have not stopped by the top button.

Pull out the crown, push the chronograph start button. You will see that the hand moves one second. once it is back to zero push back the crown. Depending on your model you might need to pull out the crown with one click for the chronograph timers and another click for the second hand.

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.

Easy, go to youtube.com and watch the video on How to.

Two push buttons is for chronograph function. When you push the upper button - chronograph starts, second push on same button - stops the chronograph. Push on lower button - chronograph resets to zero. Rate me, plz.

Pull out the crown and use either a combination or one of the cronograph buttons, this will allow you to adjust the hand positions

On Casio digital watches you need to cycle through the modes till you get to the chronograph (stop watch). Once there you can use the start stop button to start and stop the chronograph then use the reset button to set back to 00:00:00 when you need to start over.

The top button is for chronograph function and puts the chronograph seconds hand in motion. The bottom button is for resetting chronograph seconds hand to zero.
Do as follows:
1) push the top button once- seconds hand starts moving,
2) push the top button once more- seconds hand stops,
3) push the bottom button once- seconds hand returns to zero.
You can repeat as many times as you like- seconds hand will allways start the countdown from zero.
Depending on what movement your watch has(mechanical or quartz), there can be more variations, but the basics are as described.

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.
