The AetherX pairs a sculpted, flagship-style case with serious health tools — on-demand ECG, built-in GPS, heart rate, blood pressure, blood oxygen, HRV and body temperature — with no subscription, ever.
✓ Free shipping ✓ 30-day money-back guarantee ✓ Works with iPhone & Android
Six everyday health tools, one glance — wrapped in a case that turns heads.
Continuous tracking that taps you on the wrist when your numbers step out of line.
Record an electrocardiogram in moments and keep every trace filed for your doctor.
Check your oxygen saturation any time — one tap, a few seconds, full clarity.
A discreet skin-temperature sensor flags changes before you reach for the thermometer.
Light, deep and REM stages tracked automatically while you rest.
Track routes and share your exact location — straight from the wrist.
That afternoon slump, the racing pulse on a hill, the restless nights — they all leave fingerprints in your data. The AetherX gathers them quietly and shows you the pattern, so you can spot trends and build healthier habits.
No cuff on the shelf, no appointment, no rolling up your sleeve. Glance at your wrist over breakfast and your reading is there — logged, charted and ready to show your doctor at the next visit.
For wellness tracking and awareness — not a replacement for a medical blood pressure monitor.
Feel something odd? Press the sensor and the AetherX records an electrocardiogram in about half a minute, using the same electrical principle as clinic machines. The moment passes — the trace stays.
Designed for awareness and conversation with your physician — not for diagnosis.
Wear it to bed and wake to a full report: light, deep and REM sleep, overnight heart rate, and how tonight compared to last week. Once you can see your sleep, you can fix it.
Blood oxygen and body temperature quietly complete the picture of how you are really doing. A dip in SpO₂ after a bad night or a creeping temperature before a cold — the AetherX spots both from your wrist.
A sculpted case, rotating crown and a big, bright display give the AetherX the presence of watches three times its price — in a clean Black or a cool Gray that goes with everything.
