G-Steel GST-B100 G-Shock disassembly video, let's begin. First I'll
remove this screw bar on the side to
remove the watch band and then we'll
move ahead to remove all the parts on
the watch body, if you want to change the
band of your G Shock watch, this is how
you do it. Remove all four screws bar on
the sides and then change the band you
will need a 12.8mm
center cutout watch band that
has a shape like this, but just in case
you bought a third party watch band or just
a regular silicone band, all you have to
do is just cut out the band to a shape
like so with the size of twelve point
eight millimeters and then you could
plug it in there but make sure that the
third party watch band that you are
using could fit a 1.5 millimeter hex
screw like this. By the way guys, the tool that I'm using right now aren't actually a
hex screwdriver like this one, I'm just
using this because this is the only
thing that I have that could fit into
this electronic screwdriver just for
convenience, the watch is already in used
conditions so I don't really mind it at this
point to scratch it even further, besides just by doing all this process
i'm sure I'll damage it even more so
this screws are the least of my concern.
Okay done removing all four screws, next I'll remove
the watch buckle if you want to clean
your G Shock watch properly, this is how
you do it. Remove the screws, remove all the buckles,
or else waters got stuck in there and it
will rust these stainless steel parts so
push the spring bar and take the buckle
out, pull the spring bar out, take this
part out, and pull out this watch band
keeper. Just in case yours break, or if
you want change this to a metal version,
this is how you do it.
To proceed even further, to the movement, we'll need to remove six screws from the front
five screws on the side and four screws
on the back let me spend a minute to
remove all that.
okay and that is a lot of screws, I
could take this back plate out and there
we have our piezoelectric speaker and an
instructions on how to change the
battery yourself. It operates on CTL920 which is surprisingly small for watch
this big, solar rechargeable. You don't
have to change it up for at least at
first 15 to 20 years but just in case it
breaks just replace it following the
instructions but first you have to
remove this back cushion which comes in
gray matching with the o-ring back o
ring which also came in gray look
whitish but it's actually gray and that
is the battery located somewhere in this
4 to 5 o'clock position which is really
incredible the footman is made in Japan
and since it is analog and it has a
crown or crown operated the only trim of
the crown first and then we could take
this movement out.
Just by removing sll 4 screws from
this third layer actually and lift it up
like so and there you go if you want to
remove dust, out of your g-shock watch
because sometimes even if you buy the
watch brand new, there could be dust in
there. This is how you do it remove the
screws from the front and then just blow
the dust out like so, plug it back in and
you are good to go. Okay, since you could
remove the bezel from the front there's
also an o-ring at the front in black
colorway. Okay before we could remove
this side cover it is better to remove
or take the movement out on the crown
out. Just unscrew the crown
like so, but do not pull it out, just
leave it be as it is and then there's an
instructions how to do it there's a push
word over here telling you guys what to
do and all you need is a spring bar
remover tool like this where it has a
needle-end and push the pin or a lever
in there each time you pull the crown
out or you push the crown in you can see
a little tiny bit of lever moving in
there, very similar as you are removing
a crown out of a Swiss style watches.
There we go that is how you do it took
me about 10 to 20 seconds but if you
don't have the experience of doing this
you might end up spending 30 minutes
just to remove that tiny crown alone and
I like to point to you guys few things
here, the difference between a g-shock watch
crown and a regular Swiss watch or Swiss
watch crown is that there's an o-ring in
there well so far, very much similar so
that O-Ring is the things that
prevent water from getting inside your
watch so that's why it is important for
you to screw the crown back down after
you unscrew it okay and next is.. hold on, my
cat just.. I mean.. its like their sleeping time.. So okay if you look closely at this
crown, I could wiggle it and could push
it in like so because there's actually a
spring built in there so that is the
srping that helps with shork absorption
and also to avoid the crown or the shaft
for breaking if you wiggle it up as you
are setting the watch so there's really
neat kind of constructions. You cannot
see it unless you take the crown out.
Okay now we could already take the
movement out what I'm gonna do let's
just push it from the front out from the
back, like so. Should be okay,
and this is the movement, which is not
anti-magnetic at all, you'll see why because well..
spoiler, most of the hands or the gears
are made out of metal, it is metal and
plastic mixed together but they're still
made out of metal which could easily
affected with magnetic field and yeah, I just dropped the movement, that's okay, it is still,
working, the movement size is actually..
okay there you go, 34.3mm..
the movement itself is pretty small actually what makes our G
Shock watch big as I always mentioned is the padding on the sides and next is this
glass, it is mineral glass, just in case
you scratched it, you could take this piece
as it is and polish it up or if you want
to replace it finds a glass it is just a
round shape so it should be pretty easy
find a glass that has a size of around
34.99 or 35 millimeters and this
stamp it in there you're good to go. You
can find sapphire if you wanted to since
this is just mineral glass. Next, I'll
remove this side button guard.
and here it is, this is the side button
guard, if you want to clean it up or just
in case your button got stuck,
this is how you do it. Remove this thing and
then clean the underneath side of this
button or just check around here just in
case this metal plate all five of this
thing was misaligned and then fix it up
make sure it aligned back into place and
then your button should be working again.
Okay let me show you guys a few things
here about G-Steel g-shock watch, that
you cannot see anywhere else. Okay, this
is your first layer underneath this is
the second resin layer then you'll have
yourself a third protective layer, and
this is your hard-case and then you'll
have this fourth layer I would say but
basically you have this one first then
this one depending on how you view it,
and then you have your back cover, the
casing as it is feels really cheap
really weak, like I mean it is resin, not
glass fibre whatsoever, this is just
resin what makes the watch feels tough
and robust is the combination of this
this and this. That's it, now next thing is is the
movement as you can see there's this
white should I say.. movement holder or a piece of
plastic that holds about movement into place and make sure that it didn't misaligned
with the button shaft, really neat
constructions. All you have to do is just
pull it out, it was just being double sided
tape with this black tape on this side
over here, which is very visible. Take 
this one out and now we have our self the
movement as it is, before we continue
on further I'm going to remove the
battery and then remove all the hands,
all the components from the front and
then we'll move to the components on the
back, but first CTL920 battery
just use a needle like this and un-clip the
clip it down here at the front.
Every g-shock has similar type of
construction, so it shouldn't be as hard
and just pull the battery out. It is
really small, I don't have to replace the
battery because it would still
working just fine but just in case
you're already damaged just find one
which I'm pretty sure are just gonna cost
around 10 to 15 bucks which incredible
cheap, plug it back in and just follow
the instructions shown on the back.. of
the back plate or the cover and in my case it is
still working fine and I have to point
out you could hold the battery using a
metal tweezers like this you won't get
electrocuted whatsoever it could drain
the battery but since this is a
rechargeable battery you could just plug
it back in charge it up and you are good
to go. Now the watch is already stopped
working it's early and I'm gonna remove
all the hands using a simple tools like
this, you could use a proper tool, you
could spend a lot of money
doing the whole process if you wanted to,
but what I'm doing over here just to
prove to you guys that you could work
this watch out without needing to pay a
lot of money. The point here is to save
cost if you end up spending tons
purchasing a special tools and such you
just better off send it away to Casio
and get it fixed instead, you know I
rather do is on my own. I bought the watch in
used condition, it's already in used
condition, there's a lot of scratch
already on it and to be honest this is
not the first time I'm doing this, this is
the third time already, so you'll see a
lot of scratch already on it, because I'm
using this tools and also I won't be
wearing any finger glove whatsoever
just to show to you guys that you could
work your watch without your fingers
glove. If I were to disassembling a mechanical or an automatic movement then sure. We're
looking at a quartz movement here guys,
you could use all the glove, all the
protection & precautions whatsoever but
I'm not gonna do it. You could do it on
your own watch.
Okay done just remove the first second
hand this is I look like and front and
also from the back and I guess that will
be a better angle for you guys and for a
better close-ups so this is the second
hand just now that I just remove and
next I'll remove the minute hand using
similar method and similar tools.
Now removing all of the hands now I'm
gonna show you guys all the close up
just in case I haven't showed them yet
and I have to say the battery indicator
level over here and also the hour-hand
are the two hardest things to remove but
keep in mind the rest are also really hard
to remove as well but those two are the
hardest so be very careful when you're
doing the process or else you break the
hands or even worse you might break this
shaft that move them be very very
careful when you're doing this. If you
don't have experience, try not to do it
okay just as precautions there next I'll
remove this index marker which came in
silver like mostly G-Shock watch. it is only
being double-sided tape underneath it,
and also there's an LED lights over here
which is will be removed at the same
time as you lift this silver indices or
index marker. It looks like it is made
out of metal right, but if you look at it
from the back it is actually made out of
plastic. It is just um.. silver chrome
painted on top and make it looked like
matter plus can see also I had all this
texture on it so that helps with the
fake appearance as well but still if you
want to change this to black out color
way, just paint it into metallic black
and I think it will look much better,
this is the LED light for the watch
which is exactly similar like most
g-shock watch, in fact if.. yours
broken, you could actually take
an LED light out of any g-shock watch
they usually use the same component and
swapped it up or if you want to change
the LED light to a different color LED
use the same method takes one hour and
just plug it back in and then you have
yourself a different colored LED lights.
Next I'll remove the faceplate,
there we go. It is also just being
double-sided tape and the tape was
placed around here underneath this G-Shock word, so there's the hardest part
to remove once you get it out you could
just leave this plastic place out. Let me
show you guys where the location is,
there you go, there's your double sided
tape, one over here and one over here. All
you have to do is just remove this and
this, and then you could remove the
entire thing, so this is where all the
lettering all this battery indicator,
all the details that be very careful not
to scratch this but in my case already
scratched it, but that's okay. This watch was
already in used condition, I don't really mind it at this point, I don't think scratching
it even further will add more damage to
this.. this watch is already in bad
condition, and now this is this solar
panel, it looks very much similar like
any solar panel out there and I have to
say everything the watch looks to me
like it is in house made by Casio
themselves so try not to break anything.
Next is this ring on the side of this
solar panel this is the thing that hold
the solar panel, it is just being clipped
on this side, there are four of the clips
so all you have to do is just force it
up a little bit and you will comes out
pretty easily and like that, lift this
thing up and now this part also made out
of plastic is pretty flexible but do not
break this thing and now you have
yourself an access to the solar panel
and I want you guys to be very careful a
special in this area of here because
there are two springs that connect from
the circuit board underneath to the solar
panel on top, so be very careful when you
lift this thing up there's also
double-sided tape down here so just run
a screwdriver like this all around and
when you find it there will be a bit of
resistance so that's why you know
there's the double-sided tape you force
it up a little bit and now you could
lift this solar panel up so I'll show
you guys how it looks like from the back
and also from the front as well and
there's the location of the double sided tape okay, and me show you guys the
springs where is it you down here. Two gold spring I'm going to need to use my
screwdriver to lift it up be careful not
to lose this and this one as well, okay
even if you loose them, that's okay you
can find any copper wire at the same
size. Plug it in back in there and just
hope that this solar panel could detect
that and charge your watch. Okay now this is the date hands or date
marker out of your G-Steel model and
very sure they are similar like any
watch on the market, forgive me for the
nails guys. Anyway these are the two
gears that move in it and just a quick
example let me show you guys how I work
and there are three screws on top these
are the screws that hold this plate, this
plastic plate that holds these date
markers. All you have to do is remove these
threo screws and we will have access to
all the gears and how it looks like but
before we get to that, I think I'm gonna
remove this screws on the back, let see now
there are two of them, one over here and
one over here.
After you're done removing all the two
screws and then only need is a needle
like so and unclip the clips on the side
where the year the button is connected
to. Once you're done that, you could lift
this battery connector out and thats your
battery holder down there in black
and now you have access to researcher
board which is locked with seven screws
one two three four five somewhere here
six and seven. Remove all the seven
screws and then you have access to all
of the coil motors down there and also
then you could remove this battery
connector on this side but I have to
comment a little bit on here because it
looks incredible simple just a few micro
capacitors probably Bluetooth units over
here in there and surprisingly the
construction of this model is really
really clean.
Okay now done and next is just lift
this circuit board up like so and that
is your coil motors down there but be
very careful there's a small spring..
there, in between these two screws there
it is do not lose this thing or else
your coil motors or your hands-on work.
If you're gonna take the coil motor out
just take it out as it is but regardless
have to comment a little bit on here
notice the placement, single, single,
single, singl,e and double coil motors,
battery placement and how the whole
thing affect the size of our G steel G
Shock watch so there is why this G still
cannot go any smaller unless they're you
know make the call more even smaller or
just stack them up on top that again it
will make a watch thicker and that is
why the GST-B200 is smaller because
instead of using coil it uses digital
display that way they could reduce some
of the space and you know make the watch
smaller so there's the trick. But regardless,
I really appreciate what they're doing
we here because if you look at the size
of the coil model and if you compared it
to the previous generations there's a
big difference. Anyway lastly, let's remove
this tree screw from the front
And just leave this date holder I would
say and there's a copper connector some
kind down there where all of this should
go for this metal gears, three of them so do not
lose them, this is all the gears and this
is your date hand which is also made out
of plastic look at all the gears and the
front it looks really really neat but
when you look at it from the back
you'll see all the plastics stamp or the
mold marks obviously like so, okay,and I have
to comment a little bit on here.
Look at all these gears, it is made out of
metal which tells us that
casio could make like a automatic or a
mechanical movement watches but they
decided not to in this case I don't know
why but I'm thinking because of cost
reasoning if they were to use metal in
the construction of this part I'm very
sure the watch will be much more
expensive which I'm not willing to pay
and I have to point out one more thing
if you look closely there is some kind
of a milling texture, there we go. Pretty sure this is not intentional but
I love it it looks like one of those a
premium mechanical movement but it is
not a clean but it has this image on it
which is pretty cool in my opinion okay
that is all I have to say on this in G
Shock watch, if you want to know how to
fix it up just comment down below if you
have any problem any issues whatsoever
this is the type of video which I will
be referring to and looking for answers
just in case something happened this is
all the gears how it looks like just in
case they didn't move for the stock or
the brake replace them if you find if we
could find a replacement which is highly
unlikely but regardless perhaps you
could inspect your watch in the future
just in case something bad happen and
finally I hope you guys could learn a
few things in this video purchase link,
down in description box if you want to
buy the watch, it's gonna help this
channel a lot. i've spent a few weeks just
to make this video so a simple like will
be much appreciated. Thank you very much for watching this is GHF and I'm...out
