GA 100-1A1

G-Shock GA 100-1A1

This watch is packed with features, which is as to be expected from this kind of watch.

The watch has 29 different timezones, switching timezones at the press of the button, 200-meter water resistance, and military-grade shock-resistance, and that’s just scratching the surface.

The GA 100-1A1 is perfect for those who like a lot of features in a simple package.

While the functions of the watch are seemingly endless, the design is the complete opposite, with just a simple black case, and a black resin strap to keep you stylish and prepared for whatever activity.

Indoor or outdoor.


  • World time in 29 times zones, 48 cities + UTC, daylight saving on/off mode
  • 10-year battery life
  • Perfect for military and outdoor activities


  • The watch dial might be a bit dark to see


GD100-1BCR G-Shock

It should come as no surprise that this G-shock watch is packed with features, as they have never failed to impress with their incredibly utilitarian watches.

This watch can have five independent alarms for those who have a lot on their plates, four independent timezones, and a fully automatic calendar.

With this watch, staying on schedule is a breeze, especially with its LED backlight that makes it super convenient to read time, even in the darkest of places.

All of this is given to us in the classic black G-Shock case, that has been tried and tested all over the world.


  • Large and clear digital display
  • Super Illuminator LED backlight
  • Full auto-calendar


  • Might not be that big for people with big wrists

If you’re looking for durability and style, there isn’t much competition against this watch.

With the big, tough and bulky case that we’re all used to seeing from G-Shock, and the slightly underappreciated green strap that really adds great detail to the watch, there’s no way you won’t look tough and strong.

Here, we have a watch that would be great for the outdoors, be it a hike, a bike ride, or a camping trip.

And this is because of the great features such as multiple timezones, electroluminescence, 200m water resistance, shock resistance, and accurate timekeeping, just to name a few.


  • Shock resistant, mud resistant, 200m water resistant
  • Super accurate Quartz movement
  • Hardened mineral crystal


  • Only 2 years in battery life


GW9400 Rangeman G-Shock

cta button

This watch has been nicknamed the “Rangeman” and one look at the large, green case and its easy to see why.

It hosts a matte-green tone, which would go great with camo gear.

Today, the Army Rangers are usually the direct action raid force of the country filled with agile and tough military personnel ready to spring to action at any time.

That’s why this watch was designed with top-of-the-line durability.

Military-grade shock resistance, 200m water resistance, and even temperature resistance.

A lot of watches can’t perform in colder climates as sub-zero temperatures can affect the movement.

However, military personnel can’t predict the circumstances in which they might find themselves in.

And that is why having a watch that is able to withstand just about any climate and conditions on the planet is a huge plus.


  • Military Grade shock resistance
  • Low-temperature resistance (up to -10C or 14­F)
  • World time in 31 timezones
  • Green-toned case blends well with uniform


  • Only has a mineral crystal


Casio GA-700UC-3ACR

This watch comes from the “XL” series, so expect a large and tough-looking timepiece.

The case measures a whopping 53mm, so this is best suited for those with larger wrists.

The case comes in a dark green color and shares the same shock resistance as any other G-Shock model, and it hosts a very neatly designed analog-digital dial.

Combinations tend to look very cluttered and messy in my eyes, but because of the large case, the dial actually looks very cohesive.

That makes navigating the watch very easy, which is great thing since you can’t really afford to waste time trying to work your watch in the military.

The simple color choices also give the watch a very simple look, so you don’t have to worry about accidentally breaking the dress code rules.


  • Simple yet great looking design
  • Military-grade shock resistance
  • 200m water resistance
  • Large 53mm case is easy to read


  • The watch may look too large on smaller wrists


G-Shock Solar MultiBand Atomic Watch

cta button

For those of you who need the durability of a G-Shock but don’t really like the analog/digital design, then this piece could be the one you need.

It features a pure black case, so there’s no need to worry about whether or not it would match with your uniform.

The simple colorway even makes it suitable for casual and athletic wear.

This is utilitarian piece at heart, having a slightly smaller case than most G-Shock models, which also makes it less imposing.

A great design for those who want a more laid back look.

The large purely digital dial lays out all your time needs very neatly.

With the time reading, date and day display, and the Casio logo all having their own spot on the dial.

All in all a great tactical watch.


  • Durable case
  • 200m of water resistance
  • Simple, black tactical design
  • Stopwatch and alarm functions


  • The negative display can be difficult to read


G-Shock GA-100 Military Series Watches

This is yet another one of those extra-large men’s watches.

But this time, it has a tan case.

That makes the watch a great pairing for camo, especially for those who are stationed near the desert, and the large case makes reading the time really easy.

It has a combination dial that displays the day, the date, and the time.

The watch has a fair amount of functions, too.

First of these being the radio-controlled world time feature.

This can be especially useful to check the time back at home when you’re stationed overseas.

It also has the standard Casio functions such as a stopwatch and a backlit dial.

This would be a great piece for anyone but would have extra benefits for anyone stationed out in the desert.


  • Tan colored case looks good with uniforms
  • Durable case
  • World time features
  • Day, date and month display


  • Might not be the best watch for those with smaller wrists


Casio GA-100L-1A

The G-Shock line always delivers when it comes to rugged and tough watches, and this piece is no exception.

The black watch with green details has a very simple, yet rugged and great looking design.

This can easily be done because of the large 51mm case which allows Casio to be able to fit all the functions they want into the watch.

The design is military-inspired, without a doubt so there’s no need to worry about the watch not looking good when paired with a uniform.

The watch is also anti-magnetic, so there’s almost nothing that can harm this watch.

Especially when you add the shock resistance and water resistance associated with the line.


  • Simple military design
  • Durable case
  • Chronograph and calendar functions
  • Analog-Digital dial is easy to read and navigate around


  • Only has a mineral crystal


GD-120 Military Black Sports Stylish Watch

cta button

If you’re looking for a sleeker design in your G-Shock, then this is one you should definitely give some attention to.

It has a really sport design, with a rounded dial with fewer corners.

It isn’t too different from a standard G-Shock that it won’t look like a tough timepiece, however, it is different enough to give the watch its own unique flavor.

With this piece, you can keep track of the time in 4 different timezones.

Which is a great way of staying connected with friends and family when on a long deployment period.

And it also gives help with scheduling calls and conversations with people in different timezones.

It also has an LED backlight which allows you to read the time very easily, even in the dark.


  • Keeps time in multiple timezones
  • Military-grade shock resistance
  • 200m of water resistance
  • LED backlight


  • A bit smaller than most models


GD-120CM Camo Sport Watch

cta button

There’s no doubt that this watch’s design inspiration comes from the military.

It has a camo themed case, so not only will it look good with uniform, in some cases, it will actually blend with it.

This watch has a large 51mm case, so it can help you give out a tougher look, or just compliment the already tough look you have.

This watch also has radio-controlled time, which makes sure you always have the most accurate time displayed in your watch.

And when time is of the essence, this becomes a very important feature.

Aside from that, the watch has all the standard G-Shock functions such as a calendar and chronograph. A great tool for any military man.


  • Camo design
  • 200m of water resistance
  • Multiple timezones
  • Easy to read dial


  • Only has a mineral crystal

What To Look For When Buying G-Shock Watches for Military Personnel

best g shock watches for military


Military watches need to be sturdy in their design.

These watches are supposed to be worn throughout the most stressful situations.

Be it at base camp, the battlefield, or even just a hike or a camping trip, this watch will be bumped and scratched all over the place, which means that you need to look for a watch that can handle all of these and more.


Look for watches with easily read dials, as these timepieces tend to have a lot going on in the face, with multiple dials and screen placed throughout.

While this may work for some wearers, too many things on the face may make reading the watch counter-intuitive.

So to counteract this, look for watches that have an ergonomic dial which can be read no matter what time of the day it is.

Water Resistance

When looking for fashion watches, water resistance can be negligible, but that’s the complete opposite of these utility watches.

With these watches, you shouldn’t just settle for the standard water resistance, so look for watches that have at least 200 meters of water resistance, so that you can use the watch for strenuous water activities, water sports, and with some watches even for diving.


Watches such as these need to have multiple functions.

Now, finding the watch with the right complications will all have to depend on your preference.

Some watches will have 12 and 24-hour time, some will have multiple time zones, some may have multiple alarms and chronograph.

But the choice is up to you and your needs, but a watch is not a military watch if it doesn’t have multiple functions.


Lastly, you need to make sure that the watch that you’re buying is accurate.

In military accuracy is key.

A second or two off schedule can be detrimental, so research on what movement the watch uses and the accuracy of the movement.

Most watches will use a Japanese Quartz movement, due to its renowned accuracy, and frankly, it’s one of the most accurate movements a watch can use.

So make sure to pay attention to the movement of your next military watch!
