The Polar watches are not designed to be taken apart. It is a common misconception to think of them as watches and not mini computers.

The best case scenario is too send your watch and clip into a Polar Authorized Service center. Polar headquarters are in Finland and their should be a close center for you in Oslo.

Visit www.polar.fi to find your local service center.

Another thing, when you change the battery yourself the watch loses it's seal and is not watertight anymore. Polar uses a special vaccum chamber to repressurize the seal to maintain watertightness.

You have to sync your watch. Browse through my tips and you will find link for manual for your POLAR watch.

Make sure you don't have the battery in upside down. The large outside case of a button cell is the +positive side.

The only solution here can be: You have to completely reset your watch and then try to synchronize it again. In case if you've lost instructions, download them here:
