I bought this clock months ago about two. The main argument for this model for me was that the clock is less / technically styled athletic than the Polar heart rate monitors: you can wear this clock permanently good without to come out as an athlete or as an endurance athlete. For me there are two negatives: The chest strap must be well moistened before use, otherwise there is no contact / signal condition. Because the Polar straps are better with their flat back. The second point is the menu system - which is not, they would like to see as straight as I do. Thus, one should not ignore the Hadnbuch. Rare Settings to you do not get out otherwise.
