Militaria.pl is a premium dealer of Casio.


Casio is a Japanese brand founded in 1946, which has remained one of the most recognizable consumer electronics manufacturers in the world for decades. It gained global fame with its iconic G-Shock series from the 1980s, valued for its high resistance to shocks, water, and extreme conditions. The company consistently develops its technologies, introducing innovations such as Tough Solar - a solar power system - and Wave Ceptor - radio time synchronization. Casio watches are popular among professionals and people looking for reliable models for everyday use and outdoor activities. The first G-Shock (model DW-5000C), designed in 1983 by engineer Kikuo Ibe, was so durable that it was tested by dropping it from the tenth floor, and yet it still worked flawlessly. Today, Casio is a symbol of innovation, durability, and timeless style.

    Hi. I will provide a more detailed opinion that may be helpful for demanding users. It is smaller than other G-Shocks, which for me is actually a plus. On the other hand, the buttons are really small, even for my not-so-large hands. The description posted under the watch is misleading. The first error is: -"This ensures full readability of the display in complete darkness. The system is activated manually or automatically (when raising the wrist)." This watch does not have an automatic backlight function when you raise your wrist. What's more, when it’s dark and you turn on the backlight to change a mode on the digital display, the light goes out immediately after pressing the mode button. So be prepared to press the backlight button several times if you want to find an option like the timer or alarm in the dark. For me, this is a big minus. Another error is: -"measurement of average speed over the traveled route". This watch does not have this option. So, the biggest downside of this watch is the lack of a constant 3-second backlight when changing options. Additionally, the digital display is hard to read without manual backlighting. Unfortunately, the idea of the display switching off immediately after pressing a button is very poorly thought out. + small watch case + nice color - small buttons (might be difficult with tactical gloves) - backlight turns off when pressing buttons - no automatic backlighting when raising the wrist as described - no option for average speed measurement as described

    I wore it on my wrist throughout my entire voluntary basic military service and it went through really tough conditions with me. It was with me on training grounds, during crawling, rolling in mud, at the shooting range, and during many intensive field exercises. Despite such demanding use, the watch never let me down even once. I didn't have to worry about shocks, impacts, or dirt — it just did its job. What surprised me the most is that after such intensive use, there are practically no scratches on it. The case and the glass still look great. This is equipment that truly deserves its reputation for being indestructible. If someone is looking for a watch for tough conditions, this one is perfect. Below I’m attaching photos: how it looked right after the training ground and a bit later after cleaning — as you can see, the watch looks like new.

    A great everyday G-Shock. The "Octagon" looks modern and is less bulky than many other G-Shocks, which makes it comfortable to wear on the wrist and doesn't catch on clothes. The case is lightweight but seems durable, so you don't have to worry about its longevity – it's not afraid of impacts, moisture, or dirt. As for comfort – the dial has both hands and a digital display, but it's not too large, so in the dark or while moving, the smaller indications may be harder to read; this is just a matter of getting used to it. However, the number of functions is impressive: alarm, timer, stopwatch, backlight – everything works intuitively and smoothly. The SU-3 version in green looks practical and stylish – scratches or dust are hardly visible. If you're looking for a solid watch for urban use and physical activity, this will be a great choice.

    I was a bit disappointed with this watch, the buttons are very small for me, very quiet alarm, it can't wake me up. No second hand (I regret that I didn't pay attention to this before buying). It also has its positives: it's nice, comfortable, attractive, and has interesting features. I regret buying it.

    This is already my next G-Shock. Besides being reliable and indestructible, they're just very nice. I like this sporty-military style but without exaggeration. Definitely, this won't be my last Casio watch.

    Thank you for the fast delivery and quality watch! Casio, as always, maintains a high level of quality, easy settings, very light, haven't tried it for diving yet, but I think everything will be as good as always.

    Nice watch, ideal for airsoft or trips to the forest. Comfortable, doesn't pull the skin or hair. Smaller than other G-Shocks, but that's a plus for me because I don't like huge watches. Intuitive operation, buttons are big enough to use with gloves. If you need a cool tactical watch, I recommend buying it on promotion, don't hesitate :)

    The watch is pleasing to the eye. Intuitive in terms of usability. A bit smaller than other G-Shock lines, but that is not a minus; rather, it’s an interesting variation. Tested in the pool, no leaks. The price is reasonable and it’s definitely worth it.

    Very nice watch. Another G-Shock in my collection and this time I decided to go for the octagon series. I think it's worth it. It is smaller than other Casio G-Shock models, but that has its advantages. Stylish with an edge. I'll see how it performs over time, but knowing the durability of G-Shock, I hope I won't be disappointed. The dial is clear and setting it is quite intuitive. I admit, KSK points meant I got it in a mega promotion, which makes me even happier.

    Great watch!!! Comfortable and not too big. The only downside might be that setting the time takes a bit and you need to read the instructions carefully, and the lack of numbers on the dial (if you sometimes need to check the time quickly).
