The watch performs excellently even in demanding conditions. It is resistant to shocks and water up to a depth of 200 metres. The display combining analogue and digital indications looks excellent. It has a modern, solid appearance. The price matches the product quality. I definitely recommend it.

MILITARY is a premium dealer of Casio.
Casio is a Japanese brand founded in 1946, known worldwide as one of the leaders in consumer electronics. A breakthrough moment in the company's history was the launch of the G-Shock series in the 1980s, which gained cult status thanks to its exceptional resistance to shocks, water, and extreme environmental conditions. Casio is constantly developing its technologies, introducing features such as Tough Solar - a solar power system - and Wave Ceptor - time synchronization using radio waves, which ensures precision and reliability. The brand's watches are popular among both professionals and users looking for durable solutions for everyday use and outdoor activities. The first G-Shock model – DW-5000C, designed by engineer Kikuo Ibe in 1983, passed a drop test from the tenth floor and continued to function flawlessly, which became the foundation of the series' legend. Today, Casio is synonymous with innovation, reliability, and timeless design.

The watch is very durable. I have hit it against various things many times and nothing happened to it. To be honest, I mainly use it to check the time and the other functions are unnecessary extras for me. I would buy it again without hesitation. It looks great.

This is a very durable watch. I've accidentally hit it many times and nothing has happened to it. I mainly use it to check the time, as I don't need the other functions. I would buy it again without hesitation. It also looks great.
-
In my opinion, this is a perfect watch for forest trips and various military activities. The case is extremely durable, the watch works flawlessly and everything is displayed very clearly.

Casio is a brand that needs no introduction. This watch has performed well for me even in tough conditions, such as sand and water. I am very satisfied, it looks great and is highly durable. I recommend it to everyone.
-
I bought this watch recently and it pleasantly surprised me. Mainly because it is very clear and everything is easy to read. An additional advantage is its water resistance – I even use it when washing up or taking a shower. The watch is very nice, solid, masculine and light. Despite my slim wrist (16 cm), it fits perfectly. I highly recommend both the watch and the shop.

An unusual solution – the markings only glow on the scale, which makes them useless at night without the backlight. After a year I had to replace a button under warranty. Unfortunately, for some reason Polish service centres do not honour the international Casio warranty.

This is truly a masculine watch with a brilliant look. Water resistance tested – no water gets inside. However, there is one drawback – operating many of the functions is quite complicated, and most of them do not come in handy for me anyway. I bought the watch mainly for its design. For that military, tactical style, I give it the highest rating.

Above all, the watch looks great, it is very nice! A big plus for its solid build and water resistance. It has interesting features such as alarms, a stopwatch and different time zones. The backlight is sufficient to check the time at night. The only inconvenience is the operation – at first you have to get used to the options, but overall it's an excellent watch!

The watch looks good, is solid, resistant to damage and waterproof, but it has some drawbacks: very weak orange LED backlight, which does not illuminate the digital display evenly. To read the final result, for example from the stopwatch, you have to place your finger in the middle of the dial so that the reflected light falls on the display. People with vision problems may have difficulty reading the display, even in strong sunlight, because a so-called negative display is used here. It often happens that during hours like x:35 - x:45, the hand covers the display, making it impossible to read – this can be really inconvenient. Despite these flaws, I consider the product worth recommending.
-
I bought this watch as a retirement gift for my dad. He is very satisfied – the watch is lightweight, solid and easy to read.

Casio is a brand that doesn't need an introduction. Top-quality and very solid workmanship.
