CASIO G-SHOCK Explosive Crash Test

    The Japanese company CASIO does not need to be introduced, as well as its line of shock-resistant and waterproof watches G-SHOCK. But few people know how the history of the unit began, the product of which was in my crash test.


    4:44, make a wish.

    Background


    Before (and now too), a wristwatch was considered a fragile item. And once, one young man, Kikuo Ibe (CASIO's leading watch developer) decided to fix this situation - he wanted to make a watch that would not break even if it fell. To solve this problem, in 1981 a working group of three people was created within the company, who took the Triple 10 concept as the basis of their work: the watches they created had to withstand a drop from a height of 10 meters, a water pressure of 10 bar, and a service life The battery should be 10 years old.

    At that time, it was an incredibly difficult task (hello to all wearable gadgets of our time that cannot work on one charge and a couple of days) - after months of hard work, the group members were spiritually and physically exhausted, there was a danger that the project would come to a standstill and closed. However, a solution was found. According to the official version, Kikuo Ibe himself found him when he accidentally saw children playing in one of the parks. “ While pushing the ball from the ground, everything inside the ball is completely protected from the blow, ” he suddenly thought. This observation led him to create a watch with a hollow design, the module of which moved smoothly in the interior of the case.

    Then there were several years of experiments on more than 200 prototypes. In the end, an impact-resistant product was born that entered the market in April 1983 - the G-SHOCK DW-5000C-1A model . It was they who became the beginning of the unique G-SHOCK path, during which the changes affected everything except the principle of the basic design of 1983.



    I tested a CASIO G-SHOCK GD-120CM-5E electronic watch in woodland camouflage. The device is the most spotty representative of the G-Specials Collection line - there all devices are camouflaged (in other colors), or designed for other similar lifestyles.



    Since the initial discussion was specifically about the crash test, I won’t focus much on the watch’s capabilities. But at the same time, they cannot but be listed, so in a nutshell: they show the time (including world clock, 48 cities from 31 time zones), there is an auto calendar, a stopwatch, a timer and 5 alarms with the Snooze function, LED backlighting. The cost of the watch is almost 10 thousand rubles.













    The watch is quite massive (weight is 72 grams), its presence on the hand will be constantly felt, although soon you get used to the size. Both the watch and the strap are made of a special, especially durable polymer that is resistant to various external irritants.

    Let's go!


    Before the crash tests started, I spent some time on YouTube, watching how other people tormented the watches of the G-SHOCK series. It is a pity that this wasted time cannot be returned - all tests were somehow bland, boring and not indicative. Perhaps because people tormented their own watches and they had no task to break them. My initial conditions were somewhat different - the clock was not mine, but went to the test; in this case, the potential death of the device was agreed upon, so in the tests it was decided not to linger and not to play calf tenderness with the clock. Breaking so breaking. Like in a “diamond hand” - to beat hard, but accurately.

    I did not have a crash test plan as such - there were just a few sophisticated torture options that it was decided to implement on a “from simple to complex” principle. Something suggested on Twitter and Instagram, here are some of the options:

    • Wash with AVD. AVD - High Pressure Apparatus, the most famous representative - Karcher at the sink. There is an AED with a pressure of 120-220 bar, while the manufacturer supplied the watch with waterproof properties at a pressure of up to 20 bar. An interesting option - in theory, the watch should be beautifully cut with a stream of water.

    • Explosion firecrackers. In view of the upcoming Nezavisimaya Gazeta, without further ado, I took this option to work.

    • Wash in a washing machine. At first, this test seemed appropriate to me, but after the first tests it became clear that nothing interesting would have happened with the washing machine. Yes, and camouflage spots would still not be removed;)

    • Play hockey for hours. Sport is life!

    • Tumble in the sand. The easiest way to ruin the display of any gadget, about it just below.

    • Place under the jack. Why not? Every time I do tire fitting with some kind of gadget!

    • Microwave. Instant death for watch electronics and, most likely, for a microwave.

    • To shoot from the gun. In principle, next to the house there is a shooting complex, where it would be possible to agree on a reprisal with the clock. But let's be realistic: it’s clear that not one of the civilian gadgets can withstand firearms, so this option is only suitable for effective parting with the device. On the other hand, back in my school years, I was in the museum of the Ministry of Internal Affairs, and there I remember the police badge that saved the owner from the bullet - what if the clock is also bulletproof?

    In any case, already in the middle of drawing up the plan, it became clear that the clock would not survive, but it was a mystery at which stage it would be removed from the race.

    Test 1. Wear resistance of glass


    The manufacturer reports that the watch uses scratch resistant mineral glass. I don’t know what exactly is meant by mineral glass, just as I don’t know the composition of the gorilla glass, however, I was almost 100% sure that nothing would happen to the glass.

    Not a mistake. From the usual knife and other sharp objects, the watch screen does not experience any emotions - you can safely drive with a blade, there will be no traces and scratches. But the same thing can be done with many smartphones, for example, my old video with a crash test of the screen of my HTC HD2:



    However, you can scratch the screen. Like a CASIO G-SHOCK watch, or any smartphone with Gorilla Glass. According to the Mohs scale (mineralogical hardness scale), Gorilla Glass is approximately 5.5-6 points, which means that it can be damaged by any harder mineral. And there are plenty of these: for example, quartz (7 points), which can easily be in your pocket in the form of grains of sand. Easily and naturally, these grains of sand will scratch you everything in the world and the screen including - you don’t even notice. Well, or topaz / corundum / diamond - if you (or your girlfriend) wear tsatski with these stones, use diamond-coated drills, then the screens of your devices are in danger.

    There are other materials that can be used to make scratches on the screen - for example, my beloved titanium, extremely hard metal. You can easily draw something on a titanium ring on any glass, including on the glass of a CASIO watch. Sometimes I regret that the ring is titanium - all the dishes are scratched.



    It is felt that the glass is thick and very durable - even nuts can be chopped on it, nothing will happen (it’s a pity that the photo / video didn’t take pictures), although the back of the watch is much better for this.

    Test 2. Water


    The manufacturer claims not only moisture resistance and water resistance, but direct protection-protection against water (the fifth protection class, the highest at the company - up to 20 bar pressure, that is, with such a watch it is theoretically possible to dive to a depth of 200 meters).

    Unfortunately, deep-sea diving was not carried out, however, water was the first element encountered by the watch. First, just under the tap, then in the kettle of water.



    Electronics walks, and the bubbles, despite the cavities in the structure, do not exit. Boring.

    Test 3. Boiling Water


    It is especially important that the clock works in boiling water - this is useful, for example, if you cook shrimp. Because if you do not cook, they will be solid, and if you digest, they will be like porridge. Well, or with what else to stir sugar in tea when there is no spoon - not with your finger?





    I did not exclude that the plastic of the device may melt from a long stay in boiling water, or something will happen to the paint. But then I thought - these same watches were designed specifically to break off people like me during crash tests! Therefore, the clock went on and on.

    Test 4. Ice


    I have never found a working temperature range for this watch model, but this does not mean that they should not work in cold weather. On the contrary, they are simply obliged to work in cold weather.



    I had to use a refrigerator freezer in the office where the minimum temperature was set - minus 32 degrees. Just freezing the clock is not interesting, so they went to the freezer in the original stylish case in which they are sold. The case itself was filled with water.



    After a while, we got a hexagonal ice weights with a protruding strap covered with hoarfrost. We barely pulled it out, because the side of the case was in the way - we washed the clock in boiling water and decided to freeze it again in a container that was more convenient (for subsequent experiments).



    Knocked ice with a knife to the dial - go!

    Test 5. Blows and falls


    Do you need to use a watch as a brass knuckle, and on them an uncomfortable block of ice? Not a problem. No need to wait for the watch to thaw - the fastest way to free them from ice captivity is to hit the floor.



    I want to note that all previous experiments were repeated several times. From cold to boiling water, from there - again to the freezer, and so on. So with the falls. The first test was successful - the ice shattered into small pieces, and at least henna for hours. Despite the fact that they fell on one of the most “dangerous” gadget surfaces - tiles.



    Each of us sometimes nerves junk. Someone at this moment smokes cigarettes, someone swears, and someone kicks the cat or throws the phone into the wall. Therefore, it was necessary to test the CASIO G-SHOCK for this case too, so the watch again flew to the floor, but with already greater force (and without a protective layer of ice). And again they had nothing - they just bounced to the side, not a single detail fell off, not a single scratch on the watch.

    But on the third throw, unfortunately, the integrity of the watch went astray - the sentence “ Just throw from all the dope! "Was taken by my colleague too much to heart. Pay attention to the force with which the watch is thrown, as well as the fact that they first withstood the first such fall (without ice):



    The clock was broken - the blow was so strong (and, apparently, at an unfortunate angle) that the bottom metal cover was literally torn off: it was mounted on 4 screws - their legs (with threads) stuck in the watch, but the caps were torn off and the cover fell off, and with it all the contents flew out.





    But you should pay tribute to the fact that there was still no scratch on the watch! And the installed glass was safe and sound! That is, if more reliable cogs were used, then something would hardly have happened with the clock. The detached strap does not count - he just knocked out the sleeve, which after 5 minutes was put in place (the sleeve itself was looked for longer - it rolled under the aquarium).



    On the one hand, the clock fell apart and failed the test. On the other hand, I was just starting to get a taste :) The case is like new, and if you spend time assembling scattered parts, that is, there are non-zero chances that the clock would work again. Therefore, I decided to stick the lid on the superglue and consider the watch conditionally alive in order to check the mechanical strength of the case itself.

    Nevertheless, I want to note that I am surprised at the mechanical resistance of the watch. They were thrown very strongly, not at all like they were thrown in many other crash tests. And they did not break down the first time - this means that under normal conditions you can not worry about them. If someone hits them, they are pinched by the metro doors or they just fall to the floor - nothing will happen to them.

    Test 6. Firecracker Explosion


    Before the New Year holidays, there are especially many shops of various pyrotechnics on the streets. And if in childhood I had to behave myself for a few months for a pack of "corsairs", now I can afford to buy it with pocket money, without good behavior.

    It would be possible to start the clock on some kind of rocket, but the jokes are bad with these things, so I just bought three packs of Korsar-5 firecrackers and one pack of Korsar-8 - the largest that was.



    The watch strap was enough for 12 "small" corsairs - a little more space was left for Bengal lights. After all, it was necessary to somehow set fire to and detonate all the firecrackers so that the arms and legs remained in place, and all the ugliness was filmed on video. In this regard, sparklers came in handy.



    An explosion thundered (rather loud), a club of smoke appeared - there were no hours on the spot. As it was not around them. After 5 minutes of searching, at 5 meters in the grass was found a watch strap (safe and sound), and after another 5 minutes - the watch itself. And, surprisingly, also safe and sound! But again the sleeve of the strap flew out, and it was pointless to look for it in the grass. And without it, the strap could not be attached to continue testing with corsairs.



    And I thought - if from 12 firecrackers (even if they didn’t explode all at once) nothing happened, why should everything suddenly turn inside out from a slightly larger firecracker? “No,” I answered myself, and carried the watch to the next test.

    Test 7. Jack


    It is difficult to come up with a more ridiculous test for watches than hitting them with a car wheel. The weight of my car is about 1200 kg, that is, 300 kg is distributed on each wheel, roughly. And given the contact area of ​​the wheel and the size of the watch, it turns out that with the same success you can just sit on the watch - the result will be the same.



    But to use a watch as a jack (more precisely, as a gasket between a car and a jack) is already a more indicative strength test.

    I take out the jack, put the watch on it and place the structure directly under the side member of the car. For quite a long time, the car got up ... but then a distinctive clap rang out - the glass burst. Tasty and crunchy. Unfortunately, the climb would not be enough for mounting, but if you lower the wheel, then it could well be removed.



    I get the "terminator" from the press, inspect. The screen really cracked, crumbled into small fragments. Although in some pieces it was visible how thick the glass is used - about 2 mm.





    The device case also bent, some buttons fell out. According to the geometry of the damage, we can conclude that the watch was not lucky again with the tester (that is, with me) and the instrument of torture: the platform of the jack has a small depression under the protrusion on the side member, so the clock literally pushed this protrusion.



    And if the jack and the support were flat (unsafe from the automobile point of view), then the watch would have a much better chance of surviving: it would not be pressed through, but flattened. And in this case, there would be more chances to survive - even after the second "death" it can be seen how mechanically strong the material is.



    It was decided to stop further experiments on the watch, since this would not be a crash test, but a mockery of two people who died twice in peacetime.

    What's inside


    Even after the clock flew into the stairwell, I looked inside. Powered by a CR2025 battery, which, incidentally, was torn off during a throw to the floor. The manufacturer claims that the watch can work from it for 7 years, provided that the backlight will turn on only once per day, and the alarm will work for no longer than 20 seconds.









    Only one scarf, one display, one battery and several rubber seals - that’s the whole filling. Each of their layers was securely fixed in a white plastic clip on the latches.

    Total


    The Internet is full of videos with crash tests of these (or similar) watches, but almost everywhere all tests pass in a rather sparing mode. Watching them may give the false impression that the watch is generally unkillable - unfortunately, this is not so, and I have proved it clearly. If you want, you can break anything, even a cast-iron ball - therefore, having entered into a rage, do not forget that we are talking about watches. Even with reinforced armor, it’s a watch, and it won’t work if a freight train passes through it. In my opinion, it is quite logical.



    What is the scariest sound a gadget with a screen can make? That's right, the sound of a crashing screen. And if you do not do stupid things like me, then from G-SHOCK you most likely will not hear this sound. Over 7 trials, the clock twice came to an end: in the first case, electronics died (by stupidity), in the second - the shell itself. But in both cases, the circumstances were far from reality and were chosen only for reasons of effectiveness; in real life, you are unlikely to stick your hand with the clock under the jack or hammer it against the wall with all the dope. Therefore, the conclusion suggests itself - if you use the watch in normal mode, then hardly anything can happen to them at all.

    Oh yes. The watch died as part of a special project with CASIO - on its page you can win the same, only new ones!

    C upcoming!
