Tachometer-style Heart Rate Monitor?

Yeah, I've been looking at all the heart rate monitors and I really want one that is like a watch, and has a needle and a backing I can easily paint (for a 'redline' around 170-220 BPM). Even just one with a needle would be awesome, and I'd like to know if these even exist, and if they do, where to get them.
It'd be really nifty if I could somehow make my own, that would be really good.
I don't really need one, but I am a runner, so that kind of information is a bit useful sometimes. I like to monitor what's going on.
I've looked around and all I can find is digital displays, which I hate.
