While the Apple Watch series 6 and series 7 share a similar design, the Apple Watch series 7’s case features a new design – it is more rounded and has softer corners. The speakers are hidden in the grille on the left side of the device. The overall look has been slightly refined.

So the casings of the Apple Watch series 7 are also bigger, offering models that are 41mm and 45mm in size. This is an increase of 1 mm from the series 6’s 40mm and 44mm casing sizes. All of the series 7 models are heavier than their Series 6 predecessors, and that could make the weight difference between models made from aluminum and models made from stainless steel even more apparent.
In the Apple Watch Series 6 we were able to choose between space gray, silver, gold, blue, and product-red aluminum color options. In the Apple Watch Series 7 we were able to choose between midnight, starlight, green, blue, and (product) red aluminum color options.
Apple Watch series 7 is more durable than the previous series and features a more durable front crystal. This new crystal component has a more robust geometry and is almost 50 percent thicker than the parts that are used on the Apple Watch Series 6.
The difference between the Apple Watch series 6 and Apple Watch series 7 is as obvious as the difference in the size of the display. The Series 6 featured 3 mm thick borders around the screen, but the Series 7 slims down the border to just 1.7mm. It is possible to make the Series 7 Series bigger. There are almost 20 percent more displays on the Series 7 Series than on the Series 6.
Apple Watch Series 6 and 7 both have a LTPO OLED display that is retina-ready. The maximum brightness of both screens is the same, 1000 nits. But the Series 7’s display is brighter indoors when the wrist is lowered than the Apple Watch series 6. As a result, people can see the face of the watch without having to raise the wrist or wake the display.
There is a better screen on the Series 6 to allow users to enjoy the Apple Watch experience, but the Series 7 makes it more interesting with more space for UI elements and the likes of a full-size keyboard. If you have been wishing for a bigger Apple Watch display, the series 7 might be a much better option than the series 6, but for most users, the increase in size is unlikely to be too small to justify upgrading.
With the Apple Watch Series 7, you are able to charge your watch 33 percent faster than you can charge the Series 6 due to a new charging architecture. So far, the Series 6 iPhone Watch is able to charge up to 100 percent in just over an hour and a half. But the Series 7 is able to charge up to 80 percent in only 45 minutes.
