hey guys i'm Gwendolyn with iFixit and i'm here with Alex our in-house expert
for Apple watches who didn't get to go to japan i know it's a bummer for me but
I mean it's exciting that I get to do my own tear down here so I'm very excited
to be up here doing a video. Awesome, Great, I can't wait to see what's inside
first off can you tell us what you brought us today what is this
so this is a my station for removing the displays from the Apple watch
I've done about a hundred hundred twenty Apple watches for the series 1 and I'm
trying to preserve the LCD so this is a reflow station that's usually used for
laptop motherboards and logic logic boards and i'm using it as a heat
controlled heat gun, that can melt the adhesive without damaging the LCD.
smart so what kind of things do you think we're going to see inside so I'm i
already cheated and I looked our tear down from the Japan team so I i get to
know what's inside so I already know that the connectors are a little bit
different for the display and they're going to be on the bottom here so i'm
going to be coming at it in here i'm also going to be looking at the antenna
because there's a couple different versions in the series 1 i'm excited to
see which 1 they have in the series 2 and if it's consistent and i'm also looking
for the display port to see if that's still there i think i caught a glimpse of it
under the lower band but i want to see from the inside great alright let's
let's get started
alright so let's remove these bands
yeah
there we are
oh my gosh wow that is the fastest I've ever seen one of these taken apart
I mean this setup does its job and that's all we needed for so let's get it
off the table
okay great so now we can begin yeah so let's start by taking this display off
open this up
and there are the ZIF connectors. I haven't seen these before so let's try to get them
yeah
now this display should come right off
1, 2, and3
so we got the smaller one this is the thirty eight millimeter with a
resolution of 272 by 340 and it has a pixel density of 290 pixels per inch so
now that we have the display off and then try to take the battery out to
remove power from the system so i know there's a lot of heat up in here so i'm
going to dig into it and try to get it out as best I can
perfect now let's get that connector disconnected
yeah
so this battery is a 273 milliamp hour that yields a whopping 1.03 watt hour of
power
it offers thirty-two percent increase power over the previous generation so
that's kinda cool but it had a lot of adhesive compared to last time
yes at the bottom of the adhesive features a adhesive pad making a small
"L" which hold in place a lot it doesn't seem really necessary but i understand
that they don't want that rocking around in their next thing i want to take out
is this taptic engine before you can do that there's a screw in the way in this
corners i'm going to remove these connectors the microphone touch gasket
just that simple
yeah
this cable here that is connected to the back of the s2 motherboard i can get
my taptic engine out
so here's Apple's tiny taptic engine for the Apple watch super cute compared to
what I just took apart in the current iphone it's a apples linear resonant actuator it
creates a motion in a straight line as opposed to a circular motion of an
electric motor which provides that haptic feedback that you know when you
press the screen
ok so attached to this tactic engine we have the little unassuming speaker right
here which does a really cool thing and i'm super excited about it it expels
water right yeah I'm totally geeking out about this speaker it's definitely an
interesting take on how to waterproof something I mean they have gaskets and
o-rings everywhere this little speaker doesn't care about being in the water it
lets the water in and then uses the vibration of the speaker to just push
the water out and keep on truckin so cool love it
so next we're gonna start having to tackle the octopus of cables but before
we do we're going to take out the force touch gasket in the antennas that we
have a little bit clearer view of what's going on now that i started i can just
take my tweezers and gently pry it up without tearing it of course working my
way around the second set of adhesive it's about time
we should have this out in no time
Now that we have the force touch sensor gasket off we're going to be working on this antenna
three small screws but shouldn't be too much of a problem now they are the
screws out can take out this little connector holding it in
there it is so this is the antenna and it's got the cool new gps right yeah the
old one only did that Wi-Fi and Bluetooth this one incorporates a gps
location in the one and only antenna
so here I have the microphone bracket and i'm going to remove and this shows
another example of how they try to make sure this watch was going to be
waterproof with the o-ring here designed to protect it from all the water ingress
making sure that this will be water resistant up to 50 meters next I'm going
to take out the two screws that hold in the side button internal side button
bracket
this exposes the side button
besides just fall out showing the same oring they had a series one
so I've gone and remove the rest of the screws around the edge nothing new or
innovative compared to the last Apple watch but before i can get to the S2 i'm going
to try to get this mess of cables a little bit of the way. There's a little
connector down here that's trying to give me a hard time now that we have all
the bits and bobs out of the way and got all those cables away going to take a
note from my teardown team, I have a cut six pic to get underneath this s2 that
we can get it out without damaging it and hopefully perfect we get
beautiful new S2 with the connectors on the correct side. So last but not least we
have the charging coils and led for the heart rate monitor
I've taken the black sticker that they had on top of this off so you can get a
better look at it before I take it out and just magnetic so i can just take it
and peel it right off the back like that
and that shows us straight through to the back of this
fine piece of technology
and we're done and that was that was fun
These are tiny tiny pieces it's it's an amazing piece of tiny technology but
what did you kind of how do you feel about the s2 as compared to the first
version so it's really very similar
I it ends up being a lot of the same technology everything is more or less in
the same place there is only 17 screws in this one image the 18 in the series 1
it's surprising but there's a lot of complexity here again we see like as
soon as you go beyond battery or display I it's really going to be next to
impossible to repair anything I it's not that bad to open once you know the
tricks on but i think that it's going to be heavily unrepairable for a lot of
issues that you might run into
that's a bummer but thank you so much for coming on and showing us how to do
it like a pro if you're interested in seeing the entire pull teardown go ahead
