Getting the stop watch to work or are the buttons just for show?

As your watch has 3 buttons I am assuming that it has the main dial and 2 sub dials maybee to show the date. The centre button should pull out (DO IT GENTLY) and either will stop or click ,you should then rotate it to set the time, when done push it back in to start the watch running.
The 2 outer buttons probably work by pushing them in a click at a time to set there respective dials.

Hopefully, this will help...

It seems that most 4 button electronic watches have similar directions. There should be four buttons. Clockwise from top left is the Light button, followed by S2 (Stop), S1 (Reset) and finally on the lower left S3 (Mode). Who knows why they are numbered this way. To set hourly chime Hold down S1 and press S3. When all 7 day flags show the chime is on. When they are off the chime is off. To set the alarm hold down S1 and press S2. Alarm icon will display or go off. Release S1 button and display will return to normal time. Hope this works for your watch

After 10 years it will be likely that the Kinetic capacitor will need upgrading. Your watch is designed to tick in two second intervals to tell you the power is very low. The power button will work again when it has some power to show. Yorkshire Watches www,yorkshirewatches.co.uk can do the upgrade for you if your in the UK. Give them a ring.

To make it beep every hour you must first put it on the alarm mode. Then, press the START-STOP button until a little bell shows up at the left. Hope it helps!

You will have to go to Polar for this problem. Sorry.<br /> <a href="http://www.polarusa.com/us-en/">http://www.polarusa.com/us-en/</a>
