EKG and blood pressure are only availalbe in some countries, and only if you have a samsung smartphone.
I think they do work in Switzerland but I can't test cause i don't have a samsung phone
Yes, but you need a subscription, usually around 5 chf, to be activated with your operator, if it is not already included; then the watch works completely independently of the phone, the only flaw is that the battery drains faster than the Bluetooth connection
1. warranty in Switzerland is legally 2 years
2. there is usually an EU version and a CH version from Samsung.
3. should theoretically be possible: https://trendblog.euronics.de/mobile-web/blutdruck-messen-auf-der-samsung-galaxy-watch4-so-gehts-107360/
Yes, it is possible to choose from a wide range of different dials, including digital ones. The watch can display Outlook appointment reminders. And calls can also be displayed and answered.
The battery lasts just under a day. But that's not a problem because the Watch is SHIT, LTE version doesn't work properly, notifications are sometimes shown, sometimes not. I sent it back. Greetings
Yes, according to Samsung, it is set up for this: "The LTE versions of the Galaxy Watch4 and Watch4 Classic can be used for making phone calls or surfing without a connection to a smartphone".
It is important to have an appropriate mobile subscription with your provider.
As noted above:
To ensure better availability, we offer the variant imported from the EU. Good to know: When using the EU model in Switzerland, you may have to do without Samsung Pay, Bixby, WiFi calling and other secondary functions.
In addition, certain updates may appear earlier or later than for a non-EU variant.
