Query: simple but good

I had a watch just like this in a different color that I use to time my runs. I don't need anything very complicated, and so I didn't want to pay a lot for bells and whistles that I wouldn't really use. This year, my sister wanted a watch for when she goes running, and so I got her the same model as mine for Christmas -- it's very simple, but works well.
