When I bought my first Casio G-Shock in 1987, little did I know that I would still be wearing them twenty years later. This G-Shock is #4, and I can still remember the pride on my face when I got it. That watch was the biggest, toughest-looking one yet, and I ended up  arguing with the owner of a competing brand over who had the best. Experience had taught me that this was the one I wanted for hard, outdoors work, play, or just show. A G-Shock means it can keep up with you, giving reliable time and useful  functions. The most useful is a countdown timer. In fact, I've retired this watch to my kitchen, where it tracks several cooking times at once. And it is still running after ten years--no new battery. It's a great watch and will go with you everywhere.
