The Series 6 features a new, brighter display than the Series 5. It's also brighter on the inside!

This year's model not only eschews that pesky Force Touch gasket, it also has fewer display connectors to wrestle. The NFC cable is now routed through a display-side jumper—and there's only one grounding cable. We love streamlined design, especially when it simplifies repairs!

Aside from the aforementioned changes, these displays (Series 5 on the left, 6 on the right) look about the same to the naked eye.

Teardown update: Here's a closer look at the display, X-ray style. This shows the smaller, 40 mm model's screen, which we stripped apart for our YouTube audience.
