The Apple Watch Series 4 has made a giant leap forward in terms of design as well as functionality. This year, a lot has changed for Apple’s wearable. It boasts a bigger display in the same form factor, powerful internals, and an EKG sensor which looks quite promising. We have to wonder what changes the company made on the inside to achieve the new design. Well, following the teardown of the iPhone XS and iPhone XS Max, iFixit has taken the liberty to open up the Apple Watch Series 4 44mm with LTE. There are a series of changes which we will talk about later on.

According to iFixit, the Apple Watch Series 4 reveal a major design shift on the inside. The experts’ coin that while the original Apple Watch used too much glue and was awkwardly layered together, the Series 4 seems to be more thoughtfully laid out.
