About Casio G-Shock Military Watch

GShock is as a brand synonymous with durability and toughness. Known for its resilience, each piece embraces many more additional characteristics.

The other fundamental components of a G-Shock timepiece include resistance to electric shock, gravity, low temperature, vibration, water, and shock. This means that this ruggedized watch can handle hard impacts (thanks to internal components protected with urethane and suspended timekeeping modules in the way that it is structured) and inclement weather without issue.

Additional benefits of this brand can include LED light with afterglow, 4 daily alarms, an hourly time signal, 1/1000 second stopwatch, countdown timer, and 48-city world time with 29 time zones.

The G-Shock Reviews

Men’s GWN-1000E

image of G-Shock Men's GWN-1000EThe G-Shock Men’s GWN-1000E is the type of watch that has been designed to offer a variety of outdoor activities such as deep sea diving. This analog watch is large and is even larger than the Rolex Submariner. Yet it is extremely lightweight and comfortable to wear.

Atomic Time Function

This is one of the top features related to the G-Shock Men’s GWN-1000E. It has been suggested that once you take advantage of this function you will wonder why you didn’t get it before. This is especially true if you are one of those people who are fanatical about the time.

Works Well Under Water

This watch operates well under water, so is a great choice if you take part in outdoor activities involving water, such as diving. The solar-powered feature also lets you turn your watch towards the sun in colder weather. The watch may be prone to condensation underneath the glass, but this will typically clear up as soon as you go inside.

What Are Customers Saying?

Customers who have purchased this watch love the ruggedness and durability of it. The battery life is a major bonus for many users as well.

Many were surprised at the battering this watch can take; whether dropped from a rock face or deep into the water, it always comes out ticking. It is easy to see why G-Shock technology is extensively used by the military, police and other armed forces.

Some customers did have a con or two about this watch. One customer noted that the backlighting isn’t great and that they struggled to read the watch at night. It is important, as with any light, to keep it switched off until needed. By leaving the backlight on during sunlight hours, you will diminish the power of the light rendering it useless when you need it.

Others noted that the watch was a little bulky. This may be true but it is also to be expected when buying a highly durable watch. G-Shock watches are made for action and collisions, meaning they need to be dense and padded to sustain shocks and pressure.

Overall, customers were more than happy with this brilliant watch. The quality of the product ensures that it is a real investment and something that won’t need replacing shortly after you buy it. It’s a quality and very good value. Whether spear fishing or scaling cliff faces, you can be assured that your G-Shock G100-1BV will be functioning with you all the way.

G-Shock Men’s DW9052-1V

image-of-g-shock-dw9052-1v-mens-black-resin-sport-watchThe G-Shock DW9052-1V is a fine watch for anyone who frequents the great outdoors, the deep blue and the highest of peaks. As a watch made for the outdoors, it’s highly durable.

This watch is perfect for long excursions into the wilderness, where you might be scaling rock faces or swimming through rivers. It’s useful for the dark as well, as it comes with a backlight for darkness. Sometimes we need to be rougher and throw our arms about, which would shatter a lesser watch, but the G-Shock series of watches are shock resistant, so you don’t need to worry about it.

Perhaps the standout feature of this watch is that it is 200 meters water resistant, making it ideal for diving or spearfishing. Even if you were to drop it from your boat, you would probably be able to source it and find it still works. It is suited to professional marine diving, as well as serious water sports, such as surfing, sailing and jet skiing.

What Are Customers Saying?

Customers who had purchased this watch were really satisfied with the durability of this watch. Many were surprised at the amount of battering it could sustain. This is primarily down to the expertly designed exterior casing of the watch.

They were also amazed by the water pressure it can sustain. Frequent snorkelers often purchase this watch as it suits the depths at which they might be diving. The shock-resistant shell also allows for divers to knock it off rocks as they dive for exotic sea life.

Some customers had complaints about the water resistance of the watch; scuba divers will reach much greater depths than other divers. Continued pressure through regular scuba diving is bound to add excessive pressure to the watch, damaging it over time. As durable as this watch is, continued pressure of 200 meters and more will shorten the lifespan of this otherwise brilliant watch. To preserve the already lengthy lifespan of this watch, you shouldn’t continually dive to great depths with it.

Overall, this is a really great and durable watch. Customers are generally impressed with the value and quality of this product. The lifespan it offers suggests you won’t need to purchase a new watch for many years to come.

What Are Customers Saying?

Customers who have purchased this watch loved the elegant sizing of it, which makes it ideal for casual use, as well as the durability of such a small watch.

The backlighting of the clock face allows you to easily see the watch face at night, which was also a major plus for many customers. Customers who serve in the army noted how the watch was reliable throughout their training, which would involve crawling through mud, swimming through rivers, and climbing rock faces.

Some customers had complaints about the comfort of the watch, claiming it didn’t sit well on their wrist. For this reason, it’s a good idea to try a watch on before you make any purchases.

All watches are different and some may not sit on your wrist the way you would like. Likewise, all wrists are different, and so this watch simply won’t be right for everybody. All the customers loved the look of this watch, and only a few were disappointed to find it wasn’t comfortable on their wrist.

Overall, it has all the aesthetics of a retro Casio but the durability of a bigger shock-resistant watch. It’s a reliable watch that will stand the test of time, so you won’t need to purchase another for many years to come. The quality of this watch is outstanding, which is just one reason that customers come back to it time and time again.

What Are Customers Saying?

Customers have purchased this watch loved the simplicity or the design. Many watches of this caliber will be overloaded with features, many of which are useless to most users.

Some customers, naturally, did have their grievances. Some customers found it difficult to read the time, claiming the numbers were too small. This is a common problem with all watches, and so customers should be advised to check for these sorts of things before purchasing.

Anyone with diminishing eyesight will struggle to make sense of a digital watch. Others claimed that the backlight was ineffective after a number of months. These same customers left the backlight on throughout the day, and so naturally it began to lose a lot of its strength. So make sure to use backlights only when necessary, such as the nighttime.

Overall, customers love the Casio G-Shock DW6900-1V for its minimalist, classic style, complemented excellently by the quality construction of this watch.

Some also noted that it is a chunky watch, and so it may not be suitable for all customers. This is something that everyone should acknowledge when buying a watch.

Overall, customers had almost exclusively good things to say about this watch. The design and durability make it one of Casio’s finest offering, and the reviews from customers really back that up.

Casio G-Shock Buyer’s Guide

History and Origin

The Casio G-Shock watch was first created in 1983. The main goals were to achieve a 10-year battery life, withstand a 10-meter drop onto a hard surface, and be water resistant to 100 meters (10 bar).

The watch was a revolutionary idea at a time when watches were considered delicate and fragile. The G-Shock essentially created a new category, the rugged sports watch. The name G-Shock is short for Gravitational Shock, and Casio is very serious about the shock protection of the watches. The company created a series of 10 layers for maximum shock absorption to protect the inner workings of the watch.

The designers went through more than 200 prototypes while developing the watch. The watches were tested for toughness by dropping them from rooftops and high windows. The G-Shock line is still going strong 30 plus years later, with a wide variety of models designed to meet the demanding needs of many different intended uses. Later in this article, I will discuss the best G-Shock watches for various purposes.

Design & Structure

Casio G-Shock watches are some of the best-protected watches on the market. The protection starts with the unique case design. The bezel is designed to protect the case and buttons from hitting a flat surface when the watch is dropped from any angle.

Urethane resin in the G-Shock’s band turns it into a shock absorber. The hardness of the resin is carefully designed to resist shocks while keeping the band comfortable to wear. Some G-Shock models have metal bands that are designed to be scratch resistant. The bands are structured to protect against shocks while maintaining their flexibility, with a range of movement of 150 degrees.

The G-Shock is designed with a hollow structure to further protect it from shocks. The watch mechanism essentially floats in the air within the case as a result. The hollow design keeps the size of the case from getting too large. The watches are crafted with shock-resistant features throughout the design. The bezel encloses the watch in all directions to protect the face and buttons.

The cushioning material protects the inner workings of the G-Shock, such as the crystal oscillator. This reduces the effects of impacts that could otherwise cause distortions and contact failures.

High-Tech Features

The G-Shock has a rechargeable solar battery, which stores energy from light absorbed by the watch, even fluorescent lighting. No matter where you are, indoors or out, the watch is always charging unless the environment is completely dark.

I love not having to worry about batteries. If the built-in battery ever runs out of juice, I can quickly get the watch going with a few minutes of light exposure. Tired of having to reset your watch? The G-Shock has a built-in radio receiver which picks up signals from the atomic clock in Colorado. It uses that data to adjust the time automatically for you, even as you move around the country.

If you’re traveling overseas, the G-Shock’s Multiband 6 technology can access time signals from stations in Europe and Asia, so you’re covered almost anywhere you go. When the colony on the moon opens, the G-Shock will probably be able to adjust itself for lunar time, too.

Triple Sensor Technology

The G-Shock is much more than a timepiece. Its Triple Sensor feature gives you a temperature sensor and a barometer, which displays your elevation or altitude and lets you play amateur weatherperson.

The third sensor is a digital compass, which can come in handy when you’re hiking, boating, or otherwise exploring the great outdoors. Even if you have a GPS device with you, it’s reassuring to have a compass on your wrist.

Triple G Resistance

The Casio G-Shock is famous for its Triple G Resistance. The first element of that is the shock resistance that gives the watch its name. The case and bezel are specially shaped to protect the watch if it is dropped from any direction. The band works as a shock absorber.

Vibration resistance is the second aspect of Triple G. This feature protects the watch movement and helps keep your hand stable when you are experiencing strong vibrations.

The third piece of Triple G is gravity resistance. The watch can withstand 15 Gs of force, more than the human body can. This means the G-Shock is very rugged and will still work fine in extreme situations such as air racing.

Tough Movement and GPS

The Casio G-Shock is known for its Tough Movement technology, which includes the Multiband 6 and solar power technologies I mentioned above, plus auto hand home position correction and hybrid mount. The first of those helps correct the placement of watch hands in the presence of impact or strong magnetic fields. The hybrid mount is Casio’s term for the shock resistant design.
Some G-Shock models offer GPS technology. This detects your current location and figures out which time zone you’re in.

The G-Shock can even determine whether Daylight Saving Time is in effect where you are and adjust the watch accordingly. I love a watch that updates itself as I travel.
