Six reasons the SereneIQ feels less like a gadget and more like a companion.

Answer and make calls over Bluetooth 5.3 without reaching for your phone.

Zinc alloy, Gorilla Glass and IP68 water resistance — at just 23.5 grams you’ll forget it’s on.
The SereneIQ’s optical sensor keeps quiet track of your pulse from first coffee to lights out. Open the DaFit app to see clear trends across days and weeks — insight without the noise.
Built-in women’s health monitoring lets you log and predict your monthly cycle right from your wrist, with a private calendar and discreet reminders in the app.
For wellness tracking and awareness — not a replacement for professional medical advice.
With Bluetooth 5.3 calling, the SereneIQ lets you answer while cooking, gardening or carrying groceries. Speaker and microphone are built right into that slim case.
For wellness awareness and conversations with your physician — not a replacement for a medical device.
Choose from multiple sport modes and the SereneIQ records your effort while you focus on moving. From morning walks to studio classes, it all lands in the app automatically.
Dynamic watch faces and a 3D stereoscopic menu make the SereneIQ feel alive. Keep the elegant analog dial for the office, switch to something playful for the weekend — the always-on display keeps it classy around the clock.
The 180mAh battery runs 5–7 days of regular use and up to 20 days on standby. When it finally asks for power, the magnetic charger tops it up without fuss.
