I have a few watches, but my favorite is an Ironman Triathlon. I actually think it's the womens' model, but I love it anyway. It's like this, but neon green, not blue. (see Fig. 1)
Anyway, I got it because it has a COUNTDOWN TIMER, which I desperately needed for my experiments, and unlike 99% of men's watches today, it's not the size of a Buffalo. Plus, it's green. Who doesn't like green?
Also, the interface is very intuitive, and it doesn't have any weird features that I'll never use (like an altimeter... who the fuck needs an altimeter?). Overall, I think it's pretty much the best watch ever designed.
* Multiple time zones.
* Syncs up every night with NOA observatory so my watch is always on official time.
* 5 alarms. I use 2.
* Tilt-activated backlight.
* Solar powered. Though this can be annoying if you need to charge it for some reason. I usually leave mine on the dashboard of my car every once in a while.
