Bought Polar RCX5 Tour De France version in Sept 2012, found a minor scratch on the watch face under normal use ( nothing like a crash or big bang on the wall). The scratch getting bigger and I cannot even see the display during biking. I returned it to the maintenance in Hong Kong and they quoted back that I need to pay US$177 to replace the whole watch unit! Absolutely unacceptable! I now wasted US$450 on this whole package. However, luckily I switched to Garmin 910xt and found it way way WAY better than Polar in terms of ease of use and functionality. So I need to say Thank you to Polar in way that I am no longer stuck with the magnificient separate GPS unit.
