ifixit took the Apple Watch 4 apart for us and see there: the change of the display and the internal battery are relatively easy.
Once you’ve opened the watch, of course. But it is possible and although Apple relies on the funny Tri-Wing screws, it is relatively easy to disassemble and replace defective parts.
What ifixit noticed: the battery has grown by 4% and the Taptic Engine is quite large for the overall installation space of the Smart Watch. As usual, the Apple Watch is stuffed with technology. And if you see it from the inside, it’s perhaps Apple’s technologically underestimated product.
