Favorite. Watch. Ever. Seems a bit larger than what I was expecting though it compliments my wrist nicely.

Besides the looks of this watch, which is an important part when deciding whether to make the purchase or not, remember that this is a G-Shock which comes with those features that every G-Shock fan can’t live without.

Saying that this is a shock-resistant watch is redundant. The name says it all. The G-Shock line changed the way we look at watches by coming with incredibly tough timepieces on a market dominated by fragility. The G-Shock GA-400 Hyper Colors is yet another implementation of Casio’s philosophy.

On the side, you can see the rotary bezel or screw down crown (the classic term), which is very bulky. At first, this may be an inconvenience for anyone who did not own a big watch before because it may often block complete twists of the wrist but after one or two weeks the watch will feel natural and you will forget that it is there.

Other design aspects that are worth mentioning are the analog digital display which features two index hands for hours and minutes, one subdial and two digital displays for the rest of the functions like the stopwatch, alarms, countdown timer. The backlight has an orange tone that gives it a very futuristic look although it doesn’t make the dial as visible as I would expect. In very dark situations the digital displays are barely visible.

But besides the design aspects what are the features that make this watch stand out? It’s hard to begin with only one feature, but I would say that one feature that most watches lack and is vital for the active person is the magnetic and shock resistance. Basically, due to this added protection, you will be confident playing life hard with the watch on your wrist. Other than that, the countdown timer the stopwatch or the alarms are indeed standard features but indispensable in today’s times where you must always be precise in everything you do. From activities like boiling an egg to keeping track of your run or getting up for work, these features will assure you make things right and precise.

Do you travel a lot? Then the world time feature will save you from the hassle of keeping track of the time zone. Simply choose from the time zones already implemented, represented by one major city. No need to ask for the local time or wonder if you have the right time on your watch.

Other aspects like changing the batteries, is not going to be a thing to consider for 3 years from the moment you bought the watch. It would have been nice if Casio equipped this watch with their well-known solar charging system, however, 3 years of battery life is more than decent.
