Huawei is reportedly on the verge of launching its second blood pressure watch, and it's likely to be the most advanced and useful of its kind to date.

According to Huawei Central, the Huawei Watch D2 will be released this September, with the most likely release date being September 24th.

This comes after one of Huawei's wearable devices passed medical certification in China in early August.
At the moment, there are no specific details on what features the Huawei Watch D2 will offer over the original (the Huawei Watch D, which launched in 2022).

That's not to say there aren't clear avenues for improvement.

Some reviews noted the Watch D’s blood pressure accuracy is good rather than great, and it is a fairly bulky watch.

It’s 13.6mm thick and has a fairly large front-on footprint despite having a mid-size 1.64-inch screen.

Huawei has a good excuse, though. Watches like the Samsung Galaxy Watch 7 use fairly standard fitness watch hardware to reap the stats required to estimate changes in blood pressure, from a baseline measured using a blood pressure cuff.

Huawei’s Watch D has a miniature version of a blood pressure cuff, with an inflating strap, using multiple air sacs. It provides standalone readings.

The impressive part here is a feat of miniaturization, not the technique used to gather stats, which is effectively the industry standard approach.

Of course, ths Huawei Watch D2 is of limited usefulness to the average U.S. buyer as the watch will not go on sale in the States.

There is usually a gap of several months between the Chinese version and the release or announcement of the version elsewhere. Western buyers are likely to wait at least as long for versions made for audiences outside of China.

For now, however, the Huawei Watch D is fairly common in the UK and EU, which bodes well for those interested in the Huawei Watch D2.
