Do you ride the waves? Do you live for the surf? Do you just enjoy swimming and being on a board? If you answered yes to any of these, then the G-7900-2 is for you!

One of Three different styles Casio has on offer* this is a blue watch with a large screen and strap.
If you like swimming but don't want to damage this watch, well you should have no fears as it's 200m water resistant! As long as you don't press buttons in the water, it shouldn't be affected, but I would also advise against taking it to the pool (the chlorine doesn't mix well with the waterproof seal).
Taking some ideas from previous outdoor watches, this model can also withstand low temperatures of up to -20oC). This way, if you're more into mountain climbing and exploring, especially in colder temperatures, you can rest assured knowing the watch will still work fine.
For all you surfers, this watch features a tide graph on the top LCD Window, as well an option to see the moon data (which is a must for Surfing experts, but can also be useful for a lot of other professions).
At the bottom of the watch, you can see a large G Button under the words Shock Resist. This activates your backlight for when it's dark. Hold it for a few seconds and it'll turn on the Automatic Light (all you have to do is have your watch at a 45o angle and it'll light up by itself).
For other fitness junkies, or just those who like to run and time themselves, there's a stopwatch just for you.
With all of these features, and more outlined below, there's never been a better time to get a Casio Watch.
