That is all, my 610 was over prices and had features like 3 sport excerices but i never used that feature.
I had a Polar 610i but cracked it and water is getting in (at some lights i fell over)
Ohh i so i want the cheapest watch that will do these features. This may be a good xmas present for myself from my Mom :)
