This is the first clock has survived the multiple Ironman and supplies the heart rate data from the chest strap in the water. Of the functions ago prima, the division pulse, time and race time on a display is great. Analysis function on the PC is also ok. Always quite interesting then to analyze its telemetry data. Actually, my dream watch if the designers had not drunk, the clock is not worn on the wrist but next to it. This is the time trial quite cool, with everything else complete rubbish. Who can handle it and who gets the thing on sale I can present this clock only to heart.
