Introduction
Notre iPhone 7 est encore sur la table d'opération, mais nous ne pouvons pas nous en empêcher - il est temps de se pencher sur l'Apple Watch Series 2. La Serie 2 est tout à fait identique à la fraîchement rebaptisée "Series 1". Mais qu'en est-il de l'intérieur ? Avec de nouvelles fonctionnalités telles que le GPS intégré, l'étanchéité, et toute une palette de nouveaux bracelets et boîtiers, le nouvel accessoire d'Apple était prédestiné à passer sur notre table de démontage. Il est temps de voir si cet "appareil idéal pour mener une vie saine" a ce qu'il faut pour tenir la distance en termes de réparabilité.

Ce dont vous avez besoin
-
-
Nos montres sont de plus en plus intelligentes. Voyons un peu ce que la dernière génération d'accessoires pour poignet Apple a à nous offrir :
-
Écran Retina OLED de deuxième génération avec Force Touch
-
SiP (System in Package) sur mesure Apple S2
-
GPS intégré + NFC + Wifi 802.11b/g/n 2.4 GHz + Bluetooth 4.0
-
Accéléromètre + gyroscope + cardiofréquencemètre + microphone + haut-parleur + capteur de luminosité ambiante
-
Étanchéité (jusqu’à 50 mètres)
-
WatchOS 3
-
-
-
Avec la sortie de l'Apple Watch Series 2, l'Apple Watch "Series 1" a été remplacée - un nouveau modèle avec un processeur double-cœur plus performant.
-
L'arrière de la Series 2 est orné d'un quatuor familier de lentilles optiques polymer qui protègent une série de LEDs et de photodiodes.
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?
-
-
-
Armé du savoir-faire récolté auprès de la première Apple Watch et de notre expertise à manier le iOpener, nous sommes prêts à dissoudre l'adhésif et à faire sortir l'écran.
-
Un couteau, un médiator, et une bonne dose de courage, et nous voilà à l'intérieur !
-
-
-
En apparence, la Series 2 ressemble de très près à son aînée, mais une fois à l'intérieur, nous trouvons toute une série de connecteurs ZIF au lieu des connecteurs à pression embêtants de l'année dernière.
-
Et derrière l'écran, nous découvrons une multitude de matériels de contrôle :
-
Apple 343S00092
-
20211CP TD1628A
-
Contrôleur NFC NXP 67V04 (le même que dans l'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: Reconnaître et débrancher les connecteurs

-
Nous défaisons l'autre côté du bracelet pour nous attaquer à la batterie.
-
Tout comme pour la batterie de son homologue cellulaire, cette vis est tenue en place par une vis tri-point pas très sympathique. Mais avec notre 64 Bit Driver Kit, nous sommes prêts à l'affronter !
-
Un petit coup de spudger bien placé, et cette montre est désarmée.
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
-
-
-
Il ne faut pas trop y croire. C'est peut-être le calme avant la tempête.
-
Comparé à la version de l'année dernière, nous trouvons en dessous de la batterie de la Series 2 assez d'adhésif pour coller un iPad.
-
Nous n'avons jamais reculé devant une situation poisseuse, et ce n'est pas maintenant que nous allons commencer. Nous piquons, poussons, soulevons et retirons l'adhésif de ce petit paquet d'énergie. Si nous la cajolons suffisamment, elle finira bien par nous révéler ses secrets.
-
-
-
-
Une fois la colle retirée de l'envers de la batterie, nous pouvons en admirer de plus près les spécifications impressionnantes. Cette batterie a une capacité nominale de 3,77 V et 273 mAh pour pas moins de 1,03 W/h.
-
Apple avance que la batterie de la Series 2 aura la même autonomie de 18 heures que celle installée dans la montre de première génération. Le GPS doit vraiment consommer beaucoup.
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.
-
-
-
En utilisant un outil d'ouverture en plastique sur le bord de la montre, nous trouvons un capteur Force Touch et un joint similaire à celui trouvé dans le premier modèle.
-
Contrairement au modèle de l'an passé, il y a un circuit imprimé solitaire qui se cache sur le joint du Force Touch :
-
Contrôleur de capteur de capacité Analog Devices AD7149
-
-
-
Une fois le Taptic Engine retiré, nous inspectons le module d'antenne que nous trouvons reclus en haut de la montre.
-
Bon, fini la contemplation ! Il est temps de s'emparer de nos pincettes et d'en finir avec ce qu'il reste dans la montre.
Any suggestion of whether the new antenna will give better wifi connectivity than the original had?
hi where can i buy this part?
-
-
-
Nous trouvons une nappe complexe nichée dans le rebord extérieur. Elle abrite le microphone et le haut-parleur.
-
L'Apple Watch Series 2 essaie de faire des éclaboussures tout en restant sèche. Il ne faut pas être avare sur les joints.
-
À quel point ces joints assurent-ils l'étanchéité de la montre ? L' Apple Watch Series 2 résiste à l'eau jusqu'à une profondeur de 50 mètres sous ISO standard 22810:2010. Elle pourra donc être utilisée à la piscine, mais posera problème durant certaines activités.
There's no barometer on the S2 though is there?
-
-
-
Quelqu'un a parlé d'étanchéité ? Ce haut-parleur très vanté semble être fait pour travailler avec l'eau plutôt que pour y résister.
-
Contrairement au haut-parleur de la première Apple Watch, qui se noierait sous l'eau, ce module est fait pour être rempli d'eau. Il vibre et pompe l'excès d'eau qui se trouve dans le haut-parleur.
-
-
-
Il n'y a plus qu'une pièce qui nous empêche d'atteindre le ventre de la bête : cette nappe où résident the bouton home et l'encodeur Digital Crown.
-
Mais heureusement, nous ne nous laissons pas abattre si facilement. Nous passons rapidement outre cette nappe dégingandée pour arriver au cœur informatique de ce petit gadget miracle.
-
Et pour rester fidèle à la tradition de la modification d'outils dernière minute, nous utilisons un médiator d'Apple Watch tout neuf pour sortir le System in Package du boîtier arrière.
-
-
-
Et finalement, nous arrivons au SiP Apple S2 tant attendu. Il est complet, avec sa couche de résine tant redoutée.
-
En haut du SiP, confiné dans le coin gauche supérieur, nous repérons deux petits composants :
-
Capteur de pression barométrique Bosch Sensortec BMP280
-
Ce qui semble être une itération du gyroscope + accéléromètre STMicroelectronics C451 déjà présent dans la première Apple Watch
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 ?
-
-
-
Il n'y a plus qu'une gamme de capteurs confinés dans le boîtier arrière qui nous séparent de la gloire totale du démontage.
-
La série de 4 diodes inclut des diodes infrarouges, des diodes blanches et des photodiodes pour mesurer vos pulsations tout au long de la journée.
-
Derrière le lot de capteurs, nous trouvons ce que nous supposons être une bobine de chargement inductive.
No adhesive this time? Is this snap-in like some manufacturers do with their traditional watches?
How to get that sensor any idea guys!!
-
-
-
Et tout est à découvert ! Une fois l'Apple Watch ainsi démantelée, il ne nous reste plus qu'à ramasser les pièces - et à espérer que la montre sera encore étanche une fois remontée.
-
- Sans être un standard industriel, le bracelet de l'Apple Watch est facile à retirer et à échanger.
- L'écran n'est pas facile à retirer, mais ça n'est pas impossible. C'est le premier composant démonté, et il est branché avec des connecteurs ZIF faciles à utiliser.
- Une fois à l'intérieur, la batterie se laisse démonter sans problème - à condition d'avoir un tournevis tri-point Y000 approprié.
- Même si elles ne sont pas propriétaires, les toutes petites vis tri-point sont un obstacle à la réparation.
- La microsoudure est nécessaire pour remplacer chacun des câbles ruban, même si cette opération ne nécessite pas de retirer le SiP comme dans la génération précédente de l'Apple Watch.
- Le système S2 entièrement encastré rend les réparations de la carte mère impossibles.

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.
Does it still have the little external service port? I don't see it in this teardown.
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.
"The fully encased S2 system makes board-level repairs impossible."
you cannot be serious.
The improved reliability afforded by the resin encasement is vastly more important that the tiny probability that anyone would ever successfully perform a board level repair, even without the resin.
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?
My apple watch display broken so I replaced my watch display but now watch can’t pair to my phone what is the reason why my watch not pair to my phone
Someone tell me about where can i buy back aluminium cover (sideral grey/nike edition) replica of apple iwatch series 2 (42mm)?
What's between the sapphire crystal and OLED display?
