Product: CHAO XIAO MAI Life-Alert WatchBrain Fog Monitoring · Stroke Risk Grading · Blood Pressure · Sleep Tracking · SOS Alert
- The first of its kind in ChinaA watch that pioneered applying TCM pulse signals to brain fog risk grading
- Core Capability40-second PPG pulse capture — one session yields both a brain fog grade and a stress load reading
- Long-Term TrendsBlood pressure, heart rate, SpO₂ and sleep recorded daily. A personal baseline forms in 15–28 days — cross it and you get an alert.
- Tech FoundationIn-house CHAO XIAO MAI Brain Fog Model v2.0, trained on clinical data together with the Preventive Health Engineering Sub-center of the National Engineering Research Center for Modernization of Traditional Chinese Medicine
- Hardware FoundationA wrist electronic blood pressure monitor. Cuff oscillometry gives real mmHg — not an optical estimate.
Between Square and Circle — Redefining Watch Tech Aesthetics
An Elegant Dial in Champagne Gold and Samurai Black
A contemporary square watch profile with a 2.01-inch curved HD touchscreen. A wide field of view, a crisp readable interface and smooth touch response put data at a glance.
A Comfort Revolution in Cuff Material
Outside, a fine white leather grain for a premium feel. Inside, skin-friendly cuff-pressure silicone that breathes and wicks. With a tungsten buckle, the clean tone suits both business and casual wear — comfort redefined.
8-Channel Flexible Optical Array
The black circular area houses heart rate, SpO₂ and an 8-channel flexible optical array under sapphire glass for accuracy and efficiency. The square-circle contrast builds its own order — hard tech as a wrist aesthetic.
Magnetic Charging, No More Fumbling with Cables
No alignment needed — it snaps into place, making every charge effortless.
Magnetic
A magnetic charging cable comes standard. Bring the magnetic end near the back of the watch and it aligns and attaches automatically for a quick top-up.
Live Progress
While charging, the screen lights up with an animated icon and shows the battery percentage, so you always know where you stand.
Full in 30 Minutes
An efficient charging design takes you from 0 to 100% in about 30 minutes — a coffee break is enough.
Safe Charging Advice
For safety and battery life, use a standard 5V/1A USB magnetic charger and avoid non-original or high-wattage fast chargers.
Others Estimate Blood Pressure. We Measure It.
Blood pressure is the most heavily weighted modifiable factor for stroke. An estimate cannot support an alert — only real mmHg can.
A micro cuff on the wrist applies physical pressure and reads systolic and diastolic directly by oscillometry. No optical curve fitting, and no weekly calibration against a cuff monitor.Blood pressure is the most heavily weighted and most modifiable factor for stroke. An estimated number cannot support an alert.

One Touch of a Fingertip, 200Hz Captures the Pulse Wave
Connect the watch, open the capture screen, and the live pulse curve runs by itself for 40 seconds. When it finishes you get four numbers on the spot: pulse rate, pulse force, pulse rhythm and qi-blood — first-hand evidence for model grading, not a questionnaire estimate.

Brain Fog Has Four Grades. Which One Are You?
We are not asking you to tough it out — we start by measuring the discomfort you cannot quite describe.
Qi and blood nourish the brain; thinking is clear, focus and memory are steady. Only brief fatigue after overwork, relieved by rest.
Occasional dizziness and slow thinking, with forgetfulness now and then. Worse after late nights, stress or meals, but little impact on daily work.
Persistent fog, mental exhaustion from the slightest effort, declining attention and frequent forgetfulness, often with poor sleep and whole-body fatigue.
Unclear-headed all day, slow reactions, reduced comprehension, sometimes with persistent dizziness and low mood, clearly disrupting daily life.
Stroke Risk, Blood Pressure and Sleep — Managed on Your Wrist Every Day
Four sources of daily data fuse into one continuously visible risk trend line.
Watch the long-term average and the morning surge — the most weighted modifiable factor for stroke.
Arterial stiffening trends read from waveform features — the state of the vessels that mirror the brain's.
Nocturnal hypoxia suggests sleep apnea, an independent risk factor for stroke.
Signals a trend before symptoms appear, when the stress axis is out of balance and blood pressure regulation falters.
Note: The watch outputs risk trend indications, not a medical diagnosis. If abnormalities persist, seek medical attention for TCD / imaging assessment.CHAO XIAO MAI · Life-Alert Watch | Cuff BP + PPG + SpO₂ + Heart Rate Four-Source Trend Model
Four Steps to Use It — and the Report Looks Like This
Connect, measure, and this appears on your phone — readable without the manual.
Connect
Turn on Bluetooth and location on your phone, then search CHAO XIAO MAI in WeChat mini programs or scan the code.
