The biggest change coming to the Series 7 (right) is its larger display, which should offer about 20% more screen real estate than the Series 6 (left).
The Apple Watch Series 7 has a new Contour watch face that makes better use of its larger screen.
The Apple Watch Series 7 is also slightly larger than the Series 6. It comes in 41mm and 45mm sizes instead of 40mm and 44mm sizes.
You'll notice that the borders framing the display on the Series 7 are smaller than the ones on the Series 6.
The Apple Watch Series 7 is also the first Apple Watch to get a QWERTY keyboard, making it easier to respond to texts from your wrist.
The Apple Watch Series 7 can also charge 33% faster than the Series 6 when used with its new included charging cable.
The faster charging makes it easier to top off your watch if you don't charge it overnight, especially if you're able to leave it on the charger for at least 30 minutes.
The Apple Watch Series 7's screen is also slightly brighter in always-on mode when your wrist is down.
Buttons on the Apple Watch Series 7 (right) are also slightly larger than on the Series 6 (left).
Apple's new watch lineup includes the Apple Watch SE (left), the Apple Watch Series 7 (middle) and the Apple Watch Series 3 (right).
