Dear Tufina Represenative,  My Pionier GM-902-3 has had repeated problems and been returned before - I have included the Email chain in the hopes that you will see how many times I and your organization have been troubled with this watch.  The last time it was returned it was supposed to be completely replaced; however, someone decided to try and fix it again and here I am again returning it.  I hope you replace it completely this time as that is what the latest Email indicates has been decided and I am tired of returning it.  Sincerely, Mark Tomick
