User Review: Casio SGW100B-3V Multifunction Watch
Price Paid: $50
This is a pretty good watch for the price. I got it mostly for the compass. It keeps good time and so far the battery has lasted 6 months.
The compass works well but is by no means accurate enough for map work, but it will at least keep you going in the right direction. I was a little concerned that the two piece band would easily break or come off of the watch but so far it has held up.
