Your watch is battery powered or a 'quartz' watch. It is commonly refered to as a 'chronograph'. That is another word for stop watch.As well as telling time and the date, your watch can time how long an event lasts. For example, a horse race. You start the chronograph or stop watch when the horse starts and stop it when it crosses the finish line. When the next horse starts you need set it back to zero to time the next race.Operation is simple. The upper push button starts and stops the chronograph. Try it. Now with the chronograph stopped, push the bottom button. The hand return to the 12 o'clock position or the 'zero' position. Also notice the small dials on the dial or face of the watch. They record minutes and other increments of time. The large hand going around when you push the upper button is recording seconds. Hope this helps, Michael

It could be that it needs cleaning. (When a watch is described as "automatic", it means that it is a mechanical spring driven type which needs to be worn constantly to keep it wound up; I assume that yours is one of these.)

Most makers recommend regular servicing at intervals of 2-3 years and as your is older than this, then perhaps it is time for a trip to their nearest service center.

Go to bulova.com to find your local service center.

Don't know what battery but a watchmaker will be able to help you for a very reasonable cost. He will also inspect the rest of your watch, case and band. Your watch will likely need the chronograph reset also.

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.

According to the instructions for similar models in the same range, these watches should be serviced ever 3-5 years.

Perhaps yours has now reached that point.

If you wish to find the nearest service center, go to Boluva.com and after selecting your region, click on "service center".

No need to go to the shop as you can reset chrono hand yourself. Read manual and follow instructions. If you don't have manual, try this: Pull out crown and then push the button and hold it. If this does not work, try push and hold the button whilst other one is held pushed. In short terms - try to use as many different combinations as you can and you will find which way is right.

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

This is to adjust the seconds hand or minutes hand for the chronograph. Pull the crown out either one click or two ... depending on the models. Squeeze and hold the top and bottom buttons at the same time (timer stop and reset buttons). Hold down together for 2+ seconds. The chronograph hands should reset by spinning around and stopping at 0. If the don't stop right at zero, you can now adjust where they stop. Leave the crown where it is in that same position out. Press the top chronograph button and hold it down for fast movement or short presses for fine movement to adjust til it stops at the top. This will adjust where the seconds hand stops. Then click the bottom chrono button once. Repeat what you did with the top chrono button and it should allow you to fine tune the position for the next dial, and so on. When you are done, press the crown back in all the way to the normal position.

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.
