What is it that shows true masculinity? Is it the way one walks? Perhaps it’s the way a man talks? Or is it the way he talks? Well, I believe it’s a combination of a lot of things, but the top of my list is what a man wears.

His clothes and accessories speak volumes about his lifestyle. And Casio discovered this little secret long ago and started making the G-Shock series of watches. These watches are an icon of strength, of durability, of persistence, of resilience.

It’s clothed in black resin and, just like its Casio Siblings, it doesn’t disappoint. Ladies and Gentlemen, here’s the Casio G Shock GA 100 1A1 Watch Review.

Features of Casio G Shock GA 100 1A1 Watch

G-Shock Protection

Casio G SHOCK GA 100 1A1 Watch ReviewIt’s only natural that I start with this world-class feature. The G-Shock protection is Casio’s trademark creation that’s endowed to watches and make them the epitome of toughness.

With the G-Shock mark, you know the watch can resist high impact, mechanical shock and any other hardships that life might throw at it.

G-Shocks are resilient, and the Casio G Shock GA 100 1A1 carries that badge with honor. Wherever you go, the watch remains snugly wrapped around your wrist and doesn’t flinch no matter the conditions.

You have no need to disturb about its state at the end of an outdoor expedition.

Water Resistance

The G-Shock wasn’t enough for Casio. They also added water resistance to the GA 100 military watch. And it isn’t just your normal water resistance; this one allows the watch to go as deep as 200 meters.

So if you are caught out in the storm, that’s nothing for this watch, it loves rain. If you decide to take a dunk in the water, just keep the watch on your wrist. It will survive the swim.

Analog and Digital Watch

So you’re one of those who can’t decide which is better between analog and digital. And this influences your decision on buying a watch.

Now, instead of buying more than one watch why not just buy the Casio G Shock GA 100 1A1 Watch? Why do you ask? Because it has both analog and digital.

This watch has white analog hands that accurately move by the second and a digital watch as well. If you can’t decide, then have both in one watch and never fail to know the correct time.

World Time

Casio gave this watch a capability to tell the time in 29 different time zones. What you get is the time in 48 cities around the world right on your wrist.

The display can be swapped between the time in your home city and the world time.

Auto Led Light

Moving around in the dark? Not to worry because the Casio G Shock GA 100 1A1 Watch also comes equipped with a handy auto LED light.

This light brightly illuminates the face of the watch, revealing what time it is. You don’t need a separate light source with this one.

The auto light allows you to specify the duration you want the illumination to remain on when you press it.
