It's a temperature compensated quartz watch, accurate to around 10 seconds per year. This puts it right up there with the highest end quartz watches. Even if you don't care about any extra features, it's worth it just for this.

It's also the only watch I've ever seen with a fully customizable and calibratable pulsometer. I know because I added that feature myself after shopping for watches and not finding a single one that had it. Use it every day at work too.
