Your safety, always within reach
The Kardena® CARE SOS 3 helps people live independently while keeping families informed in an emergency. Press the SOS button to call up to three trusted contacts and share your live location. Automatic fall detection can trigger help if you don’t respond. With a built-in 4G SIM, the watch works without a smartphone—ideal for seniors.
Why families choose this watch
With age, risks like falls or dizziness can increase. CARE SOS 3 pairs reliable emergency tools with everyday health checks—heart rate, blood oxygen (SpO₂), blood pressure, skin temperature, and a cardiovascular alert system—to flag changes early and bring peace of mind.
Calls up to 3 contacts and shares GPS automatically.
30-second countdown with auto-call if there’s no response.
4G nano-SIM for calls, SOS, and location—no smartphone required.
Real-life examples

EmergencyMr. B (79) feels unusually tired. Regular SpO₂ readings (even more precise with the optional oximeter accessory) show a trend he shares with his doctor early.
