There are a number of services that combine wearable devices in the form of keychains or watches or mobile phones with the SOS button, and a “help desk” that can organize help when needed. Most often, this service is provided to pensioners.
But the design of such devices is not always suitable for them. For example, a man in 65 years is unlikely to want to wear a key chain on his chest or a hefty wrist watch with a bunch of buttons. But the
analog clock is in my opinion the best choice for them.

Analog Swiss watches from Limmex are already
available and cost from 449 to 749 euros. As you can see in the image, they call in turn on several phone numbers pre-entered into them, until someone answers and arranges for help.
Pros: they do not need a phone with which they would have to synchronize, and do not need a headset - the speaker and microphone are already built in.
Minus: to call for help you need to click on the button. As I understand it, there are no sensors capable of detecting a drop or change in the pulse that speaks of a heart attack.


There are a number of competitors in this area. For example, equipped with a GPS heart rate monitor
