How REALLY tough is a G-Shock (torture inside)

[jean-michel]

I have decided to test to the limit a poor G-Shock , the model I have choosen for this test is the DW-9052

http://www.lesmala.net/plongee/gshock1.jpg

Frozen during 48 hours at -18°C

Boilled in hot water (100°C) for 10 minutes

Temperature cycle test : -40°C/+70°C rapid variation and 1 hour to top/min temp : 5 cycles :

Vaccum test : watch in a vaccum chamber (normally used for thin film coatings) for 24 hours and return to ambiant pressure

Gas pressure test : the watch is pressurised at + 2 Bars, then return to ambiant pressure

Cryogenic test : the watch is vaporised with a coolant agent giving peak temperatures at -65°C

Washing machine test : the watch get a full cycle in a waching machine :

Diving test : the watch is regulary test during my dives, max depth -40 meters (picture here taken in a diving pool at -20 meters)

compression test : I drive my range rover over the G-Shock (click to read the video)

and guess what ?

The G-Shock perfectly survive to ALL thoses tests !

Thanks for sharing that Jean-Michel :-!

Now would you do those tests to your other dive watches. :-d

[tribe125]

The G-Shock perfectly survive to ALL thoses tests !And until the last test might also have been the cleanest G-Shock on the planet.

Thanks for sharing. :-!

[thorick]

What I didn't expect it to survive was the boiling water test.
Amazing result !

This far exceeds the old Timex advertising slogan "Takes a licking and keeps on ticking" :-)

[Sjors]

WOW Jean Michel,

You have guts driving over your rare millitary G-Shock. Looks like nothing had happened though.

Thanks for sharing your test.

Cheers,

Sjors

Cheers Jean-Michel!

Thanks for sharing! Makes me proud of having my G-Shocks! :-!

Been thinking of getting a DW9052-1 and those pics have done it for me.
Just bought one from the bay :-)

[JCraw]

While nothing as extreme as your tests I can relate my own "unofficial/unwanted" freeze test. I used to keep some of my watches on top of the refrigerator to keep them out of the way and away from the kids. Well it seems my GW-1500 was a little too close to the edge of the door and I opened the freezer and it fell into the icemaker bin. I looked for that watch for quite some time (everyday listening quietly on the hour for the signal) and finally after 2 months had past I was cleaning out the ice bin and found it. Took it out, rinsed off the ice crystals and put it on. Hadn't missed a beat.:-!

[Jeff_C]

At first I thought... oh wow, yet another hyped test... But you do a few extras thrown in there! I have heard that the freezing isnt really much of a test.. but your Cryo freeze is! I also like the pressure and vaccum tests! not to mention baking it! Thanks for all that!

[BruceS]

That was pretty cool JM. Now go do that to your Doxa :-d:-d

[BrandonZ]

:thanks Great post!

Nope this is NOT my military DW-9000 but a simple DW-9052 ;)

Cheers

[Gordon]

Could anyone tell me when the DW-9052 first come into production?

I've done a bit of searching but haven't managed to find anything.
They still display them on the US and international Casio site but I can see them on the Casio.jp site.

Thanks in advance.

[tribe125]

As I posted recently when I bought mine, indefatigable research by Resinbandit suggests 2000/2001.

That is awesome! Thanks for the pics/test.

Hi Jean,
Thanks for your test.I think unique & fantastic.:gold

[jean-michel]

Thanks for all your replies guys : nice to know you enjoy it
cheers
JM

[stockae92]

thanks for posting the test |>

i never doubted the G-Shock while reading it :-)

question about the Cryogenic test, so the extreme cold didn't damage/harden the bezel and the paint? as well as the LCD?

and after you drove a SUV over it, not even a crack anywhere?

[tribe125]

and after you drove a SUV over it, not even a crack anywhere?SUV? SUV!? A Range Rover... ;-)

Whatever next - a Bentley limo? :-)

[raydin]

SUV? SUV!? A Range Rover... ;-)

took the words right out of my mouth Tribe :-d:-!b-)
cheers

:-! :-! :-! Thanks !

and yes I do confirm that no scratches or anything happend after the roll over test

Hi diver!

Glad to see you here too ;-)

I was just searching this forum to find extra info on the DW-9052 that I just received this morning!

The oustside quality of that polymeric plastic looks very nice. The windows of the dial look metalic inside. Is there a metalic case underneath?

When will you pursue the series of tests? What is the next one?

Cheers,

Marc

[KVD90]

Its good to see how my G-Shock would suvive :-!

[overdriver]

wow.. nice test! thanks for posting! :-!

btw, is it ok to post your pic to other watch forum? It's foreign language forum and I will give you credit of course.

Please, let me know

[G-SAR]

A very interesting test indeed!:-!

I use this watch at work and it was quite cheap when I bought it too:-)

So after seeing this test this watch is great value for money I think!|> |> |> |>

Thanks for posting!

[Watchez]

Seeing tests like this make me love G-Shocks more and more :-!

[jean-michel]

you can use my pics without any problem on another forum, I simply ask you to give credit of the pics and make a link to my websites : http://www.lesmala.net/jean-michel/

Hi Marc, my friend !

nice to see a French diving buddy on the WUS forum !

I have not opened the DW-9052 yet so I really do not know if there is an inside metallic shell under the plastic case

I have many ideas to continue the "torture tests" of the Casio, one of the test I have done is not that spectacular but quiet tough : during my last diving trip I have carried the Casio in a pocket of my BC all the week, the watch was not rinced between dives, have stayed in the pocket all week enduring both diving and temperature cycling (I was diving in the indian ocean with an air temp over 40°C), as you can expect the G-Shock do not suffer at all of the treatment, not a single dot of corrosion can be spotted on metallic parts

I will renew this experience in my next diving trip, but this time the week will be focussed on deep dives over 40 meters

cheers

Jean-Michel,
Impressive test! I'm most amazed buy the vacuum test, that is something I'm sure they don't test when designing them. I think it would blow the glass off most lesser watches (the water proof ones at least).

What you want to do is get access to a gas "Temperature Forcer", we use them for testing silicon chips at extreme temperatures. You could take the watch from -40 upto 150 C in about 10 seconds.

Gas is blown through a small nozzle at upto 9 litres per second, the forcer can change the gas temperature rapidly, it changes the temperature of the surface you point it at very quickly indeed. Since the watch is quite thick one side will probably be above boiling point when the other is still bellow freezing point!

I'd do it myself, but I don't have a spare watch!
This is the kind of thing:

for all 4 screws case back, the case (under the bezel) is plastic. only screwdown case back has metal case.

Hello jean-michel
A superb effort:gold :gold

Loved the photos too, they just about pushing me over the edge. To think, I swore I'd only ever buy one G-shock and not get carried away (like some of you other "nutters":-x :-x .....:-d ). Especially since you chose this model, which of late is kinda getting a new lease on life (in terms of popularity). To me, this only emphasis why I like G-shocks so much. Great value for money.



Thanks for sharing!:-!






p.s. A chemical test. Perhaps with other brands of digitals too. There, that's my idea that I'd thought I'd float.;-)

[kpatt]

I was curious about what was underneath the bezel so here are some quick shots with the bezel removed.
It feels very solid and I suspect there is a thin layer of metal which this inner plastic casing is glued to. I wasn't game enough to try and pull it off.
ps It's a bugger to get the bezel back on because the buttons are freely rotating ;-)
