We have already shown you the insides of the iPhone 7; now it's time to see what has changed in the Apple Watch Series 2 in relation to the first generation clock.
Because of the watch's waterproof capabilities, Apple used a lot more adhesive to build the watch in order to seal the joints more.
Apple chose to use ZIF connectors in this generation (previously they were pressure connectors), something that facilitates possible repairs.
The watch battery is protected by three-point screws in addition to having a lot of adhesive to attach it to the housing.
It is a 3.77V, 273mAh and 1.03Whr battery, a 32% increase over the first generation Apple Watch. This watch, however, the 38mm or 42mm possibly has an even bigger battery. As we had no battery gain in itself, GPS is probably responsible for consuming all of that extra 32%.
Here is the Force Touch sensor in its glory the same used in the 2014 watch.
Under the Taptic Engine (slightly larger than its predecessor), we have the antenna that was redesigned to accommodate the GPS and the second microphone that was implemented.
Above, the loudspeaker that “spits out” the water, preventing it from entering the structure.
The S2 (chip) where practically the whole brain of the CPU, accelerometer, barometer, gyroscope, etc. is located.
The repairability score for the Apple Watch Series 2 was 6/10 (a better score than the first generation of the watch).
To those interested, iFixit also shared a video with the entire disassembly process.
