Inside Apple Watch Series 2: Display

The new Series 2 watch features a display that is two times brighter than the previous generation watch.

Thanks to a teardown by iFixit of the Apple Watch Series 2, we are able to see that its display features a "second-generation OLED Retina display with Force Touch". This is what differentiates it from the original Apple Watch. There are no aesthetic differences between the two, but its internal connector layout is different.

The new display comes in two sizes and resolutions, with the 38mm featuring a resolution of 272×340 pixels at 290ppi, where the 42mm version has a resolution of 312×390 pixels at 302ppi. Read next: watchOS 3 release date.

 

Inside Apple Watch Series 2: Water resistance

The new Series 2 is water resistant and not waterproof - as described by Apple, rather with a IPX7 rating.

Within the chassis of the Series 2 there is a lot more adhesive around the watch's display and its internal components. This is to protect the internal parts from being damaged from water.

It does mean dissasembly is harder - but we wouldn't suggest you do that, as once you've opened your Series 2 watch, it will no longer be water resistant, due to all the seals being broken.

Inside Apple Watch Series 2: Speaker

Due to the Series 2 featuring water resistance, naturally most would assume it doesn't have a speaker.

Thankfully this isn't the case, where the Series 2 does have a speaker and it's thanks to its clever mechanism that permits it.

The speaker works by filling itself up with water and once you're out in the dry will vibrate to pump the water out of its drivers.

Due to this mechanism and the automatic shutoff from the display, the Apple Watch Series 2 can be taken on swims.

Inside Apple Watch Series 2: Battery

The Series 2 watch features a bigger battery, with a 273mAh size that is rated at 3.77V and offers an impressive 1.03Wh.

In comparison to the original Apple Watch, it's 32 percent bigger, where the old one featured a 205mAh battery that was rated at 308V, offering 0.78Wh.

The new battery might seem a lot more impressive, but Apple still quotes the same 18-hour battery life. This comes down to the GPS module found within the Series 2 chassis - the power hog.

If you were brave enough to replace your battery on your original Apple Watch (after your warranty had expired of course), then you'll be glad to know that you can also replace the battery on the Series 2. However, by doing this you will no longer benefit from its water resistance. Also see: Apple Watch vs Apple Watch 2Image credits to iFixit.

 

Inside Apple Watch Series 2: GPS, Taptic Engine & S2 SiP

The new watch features a built-in GPS, a larger Taptic Engine and the S2 SiP module (featuring a dual-core processor and better graphics).

Through iFixit's teardown we can see that the antenna is a lot larger, where we suspect that this is due to the inclusion of GPS.

Its Taptic Engine is also larger, where it uses a different way of method of feedback. By using a "linear rsonant actuator", the Series 2 watch provides Apple with greater freedom for customising the feel of the vibrations, while for users like us, it changes the way it feels and is perceived as being more responsive.

The Apple S2 SiP, the module that houses the dual-core processor and is the brains within the chassis is actually flipped versus the original watch. Unlike the original Apple Watch, the Series 2's SiP is flipped, making the connector wires face the right way.

This internal design change most likely shaved a few millimetres of space within the watch, thus allowing for a larger battery and larger Taptic Engine. Read next: Apple Watch buying guide 2016.
