What HRM is on your wrist?

[e.e.cummings]

Even I can see four fields on my Garmin 310XT, which has the same screen size as the 305 in a smaller case (also it's waterproof). And as I said in the other thread, I need reading glasses to see my food when I eat....

I was reading about the Garmin 310XT - sounds like you are happy with it? Is it large - does it feel big on your wrist when you are swimming (or do you swim with it on?) I have a small wrist...
