Because of definitional issues.
It's not just China that can't use it, some countries can't use it either.
The main thing is how to define ecg role, now it is generally recognized that this is a medical role, Apple is also working in this direction, then if it is a medical role, the watch is a medical device.
According to our laws, the sale of medical devices, please have a medical device license, and then the manufacturers of the watch (that is, Foxconn this kind of) or to provide testing ecg parts manufacturers, may also need to be a medical device manufacturing license, that this manufacturer is domestic okay, foreign you have to apply for a permit in China, it is indeed very troublesome.
And this two certificates is not a business license, said to apply for the application, after applying for everything is fine. First of all, the application should be qualified to audit, to look at your entire enterprise system, including financial, production data, whether the goods can be traced, etc., the management of a company has a certain cost.
Then every year there is the possibility of the FDA flying inspection, acceptance of the inspection, the FDA is not playing around, before the financial traceability, that is, you can check the accounts, this Apple may not really be acceptable.
If it is not a medical device, it is a reference role, can not be used as a standard, then Apple publicity is in trouble.
So I think it's a matter of what is allowed by law and regulation.
But Apple Watch is still quite good for fitness sports people, and you can buy it if you like.
The Apple Watch has a wide variety of personalized dials that allow you to change and customize the settings as you wish. On the customized dials, you can add useful information such as weather, next activity, etc. It can display information about the user's heartbeat. The Apple Watch can also display the user's heartbeat, and when used in conjunction with iPhone, Apple Watch is less than 50 milliseconds off the world's standard time.
When you get a notification, Taptic Engine alerts you immediately via Tap.
Apple Watch can send Sketches, Taps, heartbeats, and more to other Apple Watch users via Digital Touch.
