$100 isn't going to get that level of quality, /k/omrade. For $50-100 you can invest in a Pathfinder series watch/ by Casio. The nicer ones are also solar recharging which helps juicing the compass/altimeter/barometer/thermometer/atomic updater.
I personally wear a PAG240B-2CR Pathfinder I bought it for ~$170 and I couldn't be happier. Lots of features yet wears weightless.
