Advice lapcounter watch, heartrate, perform.-details to pc?

Hello everyone, I´m looking for a waterproof sportwatch, which can do the following things: 1) Can it do an advanced pyramid-diagram with rising and descending distances like below?: 50 meter / 30 sec rest / 100 meter / 30 sec rest / 150 meter / 30 sec rest / 200 meter / 30 sec rest / 150 meter / 30 sec rest / 100 meter / 30 sec rest / 50 meter (*) 2) Counting laps 3) Total time 4) Total distance (*) Interesting for road running, is when I can substitute the metre-distances into time (mm:ss). Also very interesting: 5) Heartrate measuring 6) Get all the performance-details from the watch to my pc. Although I often read that regarding to points 5) and 6) there is need for a cable. And often that´s a problem with water. Btw: I don´t swin in salt water. I´ve read good reviews about the Timex Ironman Sleek 150-Lap. But I wanna be sure. Does it have the features I want? Or do you´ve an hint for an interesting alternative?
