I believe I read the primary reasons they (Polar) do this is to insure your watch is "safe for use" under water (if yours can be used swimming like mine) and to guarantee your warantee. If you take it to an outside jewelry store to replace the battery Polar will null and void your warantee....the jewelry store is not an authorized Polar dealer and "may not" have replaced the back properly etc. My model is a more expensive model (S610i) and I reluctantly choose to send it out to have the battery replaced after 3 years (even though I never swim with it)...they were prompt, efficient and they even checked my transmitter which, incidently, didn't need replacing (for free). It only took about 2 weeks if I remember correctly. I thought it was best to have it done by the company just in case I some day decide to swim with it
I really can't complain about the company at all. So far I've had the watch about 4 years or so with no problems. It was one of the best fitness investments I've ever made
