Hey Matt,

Have you looked at the FLIX watches from Timex. Just like it sounds, a quick flick of the wrist activates the Indiglo for 3 or 4 seconds. It takes a pretty pronounced "flick," but nothing too extreme. I'm a big fan of the Timex Ironman watches because they hold up well (I have one that I've beat up for probably ten years and it still works) and inexpensive (unless you step up to the ones with the heart-rate monitors or things like that, which I don't bother with.)

This one can be found at Walmart for about $35.

For what it's worth,

Chris.
