In the next model 'Apple Watch Series 7' that will appear in 2021, the bezel of the display will be even smaller and UWB support will be improved. It has also been pointed out that the new lamination technology may reduce the distance between the cover glass and the display.

UWB has been supported since Apple Watch Series 6, but it looks like the Series 7 UWB will be even better. With the improvement of UWB, the 'feature that allows Apple Pay to manage rental car membership cards, hotel room card keys, etc.' announced in watchOS 8 will be available on the new Apple Watch.

As mentioned above, the new features that will appear in the 2021 Series 7 may not be so impactful. However, it has been pointed out that new features that will appear in the coming years may be more powerful.

Of particular note is the blood glucose monitoring function. People with diabetes need to puncture their skin on a regular basis to collect blood and measure their blood glucose levels. However, with the blood glucose monitoring function installed in Apple Watch, it will be possible to measure without puncture. However, the blood glucose monitoring function is expected to be implemented in the next few years.

In addition, it has been reported from around 2017 that the blood glucose monitoring function may be implemented in Apple Watch.

In addition, there is a possibility that a 'body temperature measurement function', which is rapidly increasing in demand due to the pandemic of the new coronavirus, will be implemented. It is reported that this temperature measurement function will appear in 2022.

In addition, Apple is reportedly considering developing a more rugged Apple Watch for extreme sports enthusiasts. The Apple Watch for extreme sports is called the 'explorer' or 'adventure' edition, and it is unlikely that it will be released in 2021, and it is likely that it will be released in 2022.
