I ordered this based on the review that proceeded me. I had done a search for a heart rate chronograph and this was one of many choices. I had ordered it for the HRM and the chronography. There was no HRM as believed and the ability to program the watch was very difficult to a "beginner" like me. The buttons were very small and it almost took a hammer to get them to move. Although the band was water-resistant, to me it felt flimsy and like it could break at any time. Perhaps others have better figured this watch out, though for me, it was not. I have decided to look for something more practical and not so "up-to-date".
