简介
Our iPhone 7 Plus is still on the chopping block, but we just can't help ourselves—it's time to look at Apple Watch Series 2. The Series 2 looks all-but-identical to the newly rechristened "Series 1"—but is it the same on the inside? With added features such as built-in GPS, waterproofing, and a variety of new bands and cases, Apple's new wearable was destined for the teardown table. It's time to see if this "ultimate device for a healthy life" has what it takes to go the distance in terms of repairability.

随着Apple Watch Series 2的发布，初代的Apple Watch被“Series 1”取代——一个带有极速双核处理器的新型号。
-
Series 2的背部是由熟悉的光学树脂镜片覆盖，保护着一组发光二极管和光电二极管。
Actually, Apple Watch Series 1 has a dual core processor which the original Apple Watch didn’t have. So Series 1 is not the name for the old Apple Watch, but a new model.
This. Please pay attention to this, everyone. We need to remain aware of all attempts at companies and people trying to rewrite history.
In the Original Apple Watch only the Stainless Steel model and the Edition (gold) model had a Ceramic back with sapphire lenses and the Sport edition had a composite back. Now all Series 2 models have a Ceramic back except the Series 1 model.
This. Coming to see this. Please pay attention to this, everyone. All series 2 models is equipped with ceramic back. Even with aluminum case. That's the difference between series 0(composite back on aluminum), series 1(composite back), and series 2(all ceramic back).
Carry the same screen the series 1 and the series 2 42mm?

-
有了从初代Apple Watch收集到的和我们运用iOpener的专业知识，我们准备好破除粘合剂拆开屏幕。
-
一个小刀，一个撬片和一个富有进取心的勺子让我们进入内部。
-
-
-
从外面看， Series 2有着和上一代非常相似的外观。但当看向内部时，我们发现一套ZIF（零插入力）连接器取代了去年使用的奇怪的按压式连接器。
-
在显示屏的背面，我们找到了隐藏着完整主控硬件。
-
Apple 343S00092
-
20211CP TD1628A
-
NXP 67V04 NFC Controller (also found in the iPhone 7 Plus)
Please update this to show how to disconnect the ZIF connectors. I had to resort to just yanking them out and then shoving them back in, which seemed to not affect the display at first but after a day the screen is no longer working at all, so I’m guessing I destroyed the connectors and therefore the watch, permanently.
Hi Bryan, thanks for repairing your Apple Watch Series 2. Unfortunately this (and any other) teardown is not meant to be used as a guide. But stay tuned, we’re in the process of preparing Series 2 guides (including the display). If you’re unsure about a connector in the future, you can look them up here: 认识和断开线缆连接头

我们从手表主体上滑动取下剩下的表带并开始探究电池。
-
和具备蜂窝通信能力设备的电池支架一样，这一块被不友好的三角螺丝固定。幸运的是，我们的64合一螺丝刀套装足以胜任这项任务！
-
利用我们的撬棒熟练地撬动，切断手表供电。
So indeed according to the image the wifi antenna has moved to the right near the Digital Crown rather than the more familiar one we saw on the first generation on the top row just above the Taptic Engine and the speaker module
-

-
哇哦，就像我们说的，如果它看起来像真的，那么它有可能真的是。
-
相比去年的Apple Watch，第二系列的电池下表面的使用的粘合剂足够粘住一个iPad的屏幕了。
-
我们从来对一个棘手的情况让步，这次也不例外。我们反复从电池上剔、捅、拨、拉粘胶，清理干净然后揭示它的秘密。
-
-
-
-
把胶水从电池背面剥离后，我们可以更近地看到它清楚规格。电池额定4.35V，273mAh，电量高达1.03Whr。
-
Apple宣称Series 2将拥有和第一代相同的18小时的电池续航，所以GPS一定消耗了大量的电量。
I am glad the battery is bigger than the original Apple Watch. As a Pebble watch owner, I have been leery of the low battery life of the original Apple Watch. I would like to see a teardown of the new Apple Watch Series 1. I would like to see if the new battery in the Apple Watch Series 1 really is the same size as the new Apple Watch Series 2. (I know that the “published” battery life shows them with similar battery life's, but I take that published data with a grain of salt…) The GPS and water proofing of the Apple Watch Series 2 are not features that are particularly important to me, but battery life is. If the new Apple Watch Series 2 has a bigger battery than the new Apple Watch Series 1, that might make me look into the Apple Watch Series 2 (I’d keep GPS off), but if they both have the same battery, then I would lean toward the new Apple Watch series 1.
Can you measure the dimensions of the battery and post them?
Alex how old is your battery?
Mine is over 2 years, reports say battery still fine but it doesn’t take charge well and having issues updating.

用一个塑料开启工具揭开手表边缘与原先的型号相似的中发现的Force Touch传感器和垫片。
-
和2015款的相似，Series 2使用Force Touch来感应屏幕上的向下压力。我们最早在13英寸Retina显示屏的Macbook上遇到苹果使用这项技术。
-
和去年的型号不同的是在Force Touch垫片上隐藏着一个单独的芯片
-
Analog Devices A07149 电容传感控制器
-
-
-
取出线性马达后，我们检查发现，天线模块藏在手表的顶部。
-
发呆够了吧——是时候把我们的镊子用在这块手表剩余的部分了。
Any suggestion of whether the new antenna will give better wifi connectivity than the original had?

在外环上，我们找到了一个复杂的电缆组件，连接到一个麦克风。
-
Apple Watch Series 2试图在水的飞溅的同时保持干燥。这就需要垫片和O形圈必不可少。
-
这些垫片和O形圈有什么用呢？它们让Apple Watch Series 2满足ISO标准 22810:2010 50米防水要求。这意味着它在水池里会完好无损，但是在特定情况下可能会失效。
There's no barometer on the S2 though is there?
-
-
-
阻止我们到达这个“野兽”腹部的最后一片就是这个带状电缆组件了，也就是Home键和数码表冠编码器所在之处。
-
幸运的是，没有什么拆解是可以轻易挫败我们。我们很快的移去这个瘦长的组件来得到这个小小的神奇可穿戴设备的核心。
-
并且，保持最后一刻的修改工具的传统，我们充分利用我们的全新苹果手表开启片从后部外壳内取出系统级封装芯片。
-
-
-
我们最终到达了期待已久的被树脂外壳包裹着的Apple S2 SiP.
-
在SiP的背面，夹在左上角，我们发现一对微小的组件：
-
博世BMP 280气压传感器
-
可能是上一代Apple Watch中迭代的意法半导体C451陀螺仪+加速度计
Any reason why you guys did not open that shiny module? Would be interesting to see what kind of memory is in there as well as the application processor to memory interface.
From the first Apple Watch Teardown: "Unfortunately, our first look is obstructed—that S1-emblazoned silver cap isn't a cap at all. It's a solid block of plasticky resin, hiding treasures deep within."
This is what they were referring to as the "dreaded resin enclosure"
That is not a second microphone, it is obviously a barometric pressure sensor from Bosch Sensortec
Apple don't claim the watch has a barometer. Does the tear down indicate it has one? Did the first watch have this component in it?
Hi Dan, No the 1st Apple Watch doesn't have a barometer, but they learned that it is very important to get accurate calorie measurement, Additionally you get the absolute height and a weather station.
Any thoughts on why the watch does not count stairs climbed despite the presence of a barometer?
It looks certain part like left side of middle area thinner than the other area. Is that any reason ?
-
-
-
完成我们最后光荣的拆解，就剩装在手表后盖里传感器阵列了。
-
这个四传感器阵列包括红外传感器，可见光发光二极管和光学传感器来追踪你一整天的心率。
-
随着传感器组件的 移出，我们看到了在盖子里我们所猜测的感应充电线圈。
No adhesive this time? Is this snap-in like some manufacturers do with their traditional watches?
How to get that sensor any idea guys!!

Here we go ....! The best part of staying up late is to be the first to get hands on teardown these little monsters packed with loads some of the most intricate and advanced pieces in tech manufactured to date
Hmmm... does this mean the Apple Watch might actually be repairable by repair shops? The display looks a lot easier to take apart. Minus the likelihood that repairing it may render it not "swim proof" anymore.
True I've had loads of issues before while repairing the Apple Watch specially with the glue that becomes almost useless the minute you pop the screen off and not to forget the tiny metal bracket holding the display and digitiser flex in !! This indeed looks repairable
I've never repaired it, but I was warned not to. Perhaps now this will change with a few ZIF connectors.
It isn't as easy as it looks ! I was warned by many too ....I infact ripped one of my first motherboard flex cables off in the past ...by curiosity didn't stop me ! You always get it right the next time ! I'd suggest on picking up one of the demo units from eBay to try your stunts right as they are as low as $100 to see your first teardown come off and then you can repair your customers watches easily after you tear one down for yourself
Great idea! I definitely need to pick one up first to test it myself.
I'll have to wait for a month atleast before I can get my hands on ! Moreover the 2nd gen ones will be out late on eBay ...! And the shipping could take ages if your not in the states but it's worth it still
Does it have the same diagnostic port Apple Watch Beta had?
According to settings it can store up to 2gb of songs
Jesus! The capacitor in step 4 picture 3 on the right is nearly falling off! Quality control is minimal here!
the question is how was the metal shielding removed. If you see earlier photos, those areas were protected. Those protection needs to be removed before 3rd photo could be taken. If excessive heat was applied, of course the solders holding those components would melt, causing them to look like that.
Yes, we had to desolder the metal shield. That damaged some components underneath. If you've got a better technique for removing these shields, we're all ears!
Kyle Wiens I'd love to see you guys teardown the S2 from the metal housing if that's a possible ! I know it's a destructive process at times but if you could I'd be greatful
See Step10, there is an amazing multi-pin connector!
Does anyone know who is the supplier of this connector?
Maybe the connector is from murata！
And where's the "service port"? no word about it...
What about the second mic hole> Not found on the original Apple Watch!

I wonder, they mentioned the series 1 will get the dual core CPU, but not if the GPU and the rest of it were the same. Are they?
That's probably a question that' down to Chipworks. And how about RAM?
Zone of Tech says it has 1GB of system ram up from 512MB in the original models.
I want to buy one.
I've been trying to get that info, and nobody from iFixit or anywhere else for the matter is able to reply...
My series 2 has some little doors in the same place as the first generation, however it looks smaller this time - it is smaller in length than the button for band release...
Afew weeks ago I bought on flea-bay a "Smart Watch" for all of 16 GBP - this has a removable battery and provision for a SIM card and extra memory micro-SD, so is a true "Wrist Communicator" - (and if you don't know what that means look up Dick Barton !).
So this cheap Chinese watch goes further than Apple - and does a variety of things; above all is the ability to dispense with a paired phone. It is called "APLUS" and I have no connection with the seller other than being a satisfied user.
How do the Chinese do this so cheaply; how long before Apple will offer an internal SIM ?
Last time the prototype Gyro was published as InvenSense. That was a good guess based on the fact InvenSense is Apple's go to company for motion technologies. But it ended up being STM. That was because STM was first there in the original design.
Now the guess is "Likely an iteration of STMicroelectronics C451 gyroscope + accelerometer". Based on the fact STM was in on iWatch1. But the iWatch2 has diiferent requirements. This gyro must provide a navigation solution and turn off the power hungry GPS 80% of the time. InvenSense excells in this capability.
I would be highly surprised if InvenSense does not have the best 6 axpoThe real question in my mind is did Apple use InvenSense Software? If so better margins should be coming.
How much storage does it have??
According to the info in Settings -> About in the watch Series 2, 38mm, it has 5.7 GB internal capacity.
Apple 343S00092 is a dialog semi PMIC

Can you comment on this additional seam that can be found on this Reddit thread? https://www.reddit.com/r/AppleWatch/comm...
Anyone knows how the antennae RF connections are done?
Is there an improvement in the heart rate sensor? I know I'm my Apple Watch Series 1 (sports version) it seems a little slow to pick up my heart rate and also refresh when I begin exercise. Anyone know how often it 'refreshes' also?
hey, do you have any ideea is the sapphire led display from series 1 compatible with series 2 ? somehow I broke mine and i can't seem to be able to find one to buy and I'm still trying to avoid the apple store since it was a gift and haven't got applecare+ for it ...
Hello, I have an Apple watch 42 mm the first model q was released. It was working normal and suddenly started to restart and stay in that infinite lopp. Is there anything that can be done to reverse this situation?
Wonder what happened with the barometer. Maybe they disabled it last minute to save on battery.

In regards of how to remove the shielding without suffering component damage, you could physically cut it off. I did that with an iPhone 5 logic board, although it damaged some coils. There must be a more precise way to machine it off.
Hi guys. Excelent tear apart guide. Just wanted to ask if by replacing the screen on the watch series 2, is there any way to get the watch sealed again so one can swin with it with no problems?
I would love to see some detailed photos of the chips on the motherboard - to get an understanding of the specs of the components - GPS, Motion detectors, memory, CPU etc.

That’s a little beyond iFixit’s abilities in a case like this, but our friends over at TechInsights have taken it a lot further.
Although board level repairs aren’t viable, is it possible to replace the board of an apple watch? When putting the watch back together, did it still seem waterproof?
