Core Health
The 4 Pillars of Precision Health Monitoring
Features that separate the CXS10 from every other smartwatch at this price
Not an estimate. A Measurement.
Most smartwatches use optical PPG sensors that guess your blood pressure — with ±15mmHg error, they're unreliable for health management.
The CXS10 houses a genuine Japanese Murata piezoelectric micro air pump: the strap's internal airbag inflates, the pressure sensor reads systolic/diastolic pressure directly, then the valve releases.
This is the exact same principle as the arm cuff at your doctor's office — miniaturized to fit on your wrist.
🟢 Murata Japan — Global Piezoelectric Leader Since 1944.
Your heart, In 6 dimensions.
Powered by a Texas Instruments AFE4950 wearable analog front-end (0.7 µVrms noise, 109 dB PPG SNR), it captures a 30-second single-lead ECG and simultaneous photoplethysmogram.
The onboard AI analyzes heart rate, heart rhythm regularity, HRV-derived stress and fatigue levels, and calculates a comprehensive cardiovascular wellness score across multiple dimensions — including cardiac load, vascular elasticity trend, and arrhythmia alert.
Swipe through 6 health indicators on your watch, then view the full ECG report and export PDF in the app — ready to share with your doctor.
🟢 This device is a wellness tracker, not a medical device. It does not diagnose, treat, or prevent any disease. Always consult a qualified physician for medical advice.
6 health metrics.1 tap.
The CXS10 activates multiple sensors simultaneously — air pump BP, ECG electrodes, SpO2, heart rate, fatigue algorithm, and EDA emotional sensor — all in one coordinated session.
It completes in as fast as 30 seconds. No mode switching. No waiting between measurements. No rebooting sensors.
It’s the closest thing to a personal health hub you can wear on your wrist. Perfect for daily check-ins before your morning coffee or after your evening walk.
Your stress has a number.Now you can see it.
The built-in EDA (electrodermal activity) sensor measures micro-changes in your skin's electrical conductivity — a direct window into your sympathetic nervous system.
Track your stress index throughout the day, identify trigger patterns, and monitor long-term emotional well-being trends based on longitudinal EDA data.
Paired with Nighttime HRV monitoring, you get a complete picture of your mental and emotional wellness — not just your physical numbers.
Metabolic & Body
Beyond the Heart — Full Metabolic Intelligence
Non-invasive trend tracking for glucose, uric acid, lipids, and body composition
Trend monitoring tool
The CXS10 uses advanced multi-wavelength optical sensor arrays combined with AI-powered metabolic modeling to provide non-invasive trend assessment for three key metabolic indicators.
Track how your meals, exercise, and lifestyle affect your glucose trends.
Monitor uric acid fluctuations — especially useful for understanding your body's response to diet and hydration.
Keep an eye on blood lipid trends for general cardiovascular wellness.
🟢 This device is a wellness tracker, not a medical device. It does not diagnose, treat, or prevent any disease. Always consult a qualified physician for medical advice.
Know what you're made of.
Bioelectrical Impedance Analysis (BIA) sends an imperceptible, safe signal through your body to measure four key composition metrics: body fat percentage, skeletal muscle mass, body water percentage, and BMI.
Unlike a bathroom scale that only shows weight, the CXS10 reveals what's actually changing — are you losing fat or muscle? Staying hydrated?
Track your progress week over week and see the real results of your fitness journey.
24/7 Monitoring
Round-the-Clock Health Surveillance
Automatic tracking that works while you live your life
Your heart never sleeps.Neither does our monitoring.

Nighttime Heart Rate Variability (HRV) analysis continuously monitors your autonomic nervous system balance while you sleep — a key indicator of recovery quality, stress resilience, and cardiovascular fitness.
Set personalized thresholds and receive instant alerts when your heart rate goes outside your normal range. Track resting heart rate trends to spot meaningful changes early.
The 8 hours that define. your 16 waking hours.
Automatic sleep stage detection tracks deep sleep, light sleep, REM, and awake periods — no manual logging required.
Overnight blood oxygen (SpO₂) monitoring continuously tracks your oxygen saturation levels, helping you understand your respiratory patterns during sleep.
Wake up to a comprehensive sleep score with personalized, actionable tips to improve your rest quality night after night.
Your body talks in degrees.
Continuous skin temperature monitoring establishes your personal baseline over the first few days of wear.
Once calibrated, the CXS10 detects even subtle deviations that may reflect early signs of temperature-related changes — such as possible fever onset or natural physiological shifts — often before you notice anything unusual.
View 24-hour temperature curves, weekly trends, and receive early-warning alerts when your temperature deviates significantly from your established normal range.

Frequently Asked Questions
Note:
This device is a wellness tracker, not a medical device. It does not diagnose, treat, or prevent any disease. Always consult a qualified physician for medical advice.
Is this a medical device? Can I rely on the blood pressure readings for health management?
The CXS10 uses Japanese Murata piezoelectric air-pump technology — the same mechanism as clinical arm cuffs — delivering ±3mmHg accuracy. It is CE (EU) and FCC (US) certified for safety and electromagnetic compatibility. However, the CXS10 is not FDA-approved as a diagnostic medical device. Use it for daily health tracking and trend monitoring. Always consult your doctor for medical decisions, diagnosis, or treatment. Many of our customers share their CXS10 data with their physicians as a supplementary tracking tool.
How is air-pump blood pressure different from the optical sensors in other smartwatches?
Optical PPG sensors estimate blood pressure indirectly from light reflection patterns on your skin — typical error ranges from ±10 to ±30mmHg, making them unreliable for health management. The CXS10 physically inflates an internal airbag inside the strap, directly compressing the radial artery and measuring systolic/diastolic pressure via an air pressure sensor, then releases via a micro-valve. This is the exact same oscillometric principle used in arm cuffs at your doctor's office — miniaturized to fit on your wrist.
Does the CXS10 require a monthly subscription?
No.The G band app is 100% free with no monthly fee, no paywalled health data, and no hidden costs. All health metrics, trend charts, ECG PDF reports, sleep analysis, family sharing, and watch face customization are included. No subscription. No in-app purchases. Completely free, forever.
Is the ECG function accurate? Can I share it with my doctor?
The CXS10 captures a Lead I ECG using a Texas Instruments AFE4950 analog front-end chip with high sampling rate technology.A higher sampling rate means the device captures more data points per second from your heartbeat, resulting in a smoother, more detailed ECG waveform. This allows the AI analysis to detect subtle variations in your heart's electrical activity with greater clarity — supporting more accurate rhythm classification and heart rate variability (HRV) assessment.
The result is a clearer single-lead ECG trace that helps you observe your heart's patterns over time. Export the full waveform as a PDF report from the G band app for your personal records or to share with your healthcare provider.
Can I use it with my Phone? What about language support?
Yes — the G band app supports iOS 13.0+(iPhone) and Android 8.0+. Download free from the App Store or Google Play. The watch display supports 13 languagesand the app supports 36 languages, including English, Spanish, French, German, Italian, Japanese, Chinese, Korean, Portuguese, Arabic, and more.
How long does the battery last?
3–7 days of typical use (with daily BP checks, continuous heart rate, sleep tracking, and notifications) on a single charge. Up to 15+ days in standby mode. Full recharge takes approximately 90 minutes via the included magnetic charging cable. Battery life varies based on usage patterns and settings.
Is it waterproof? Can I swim or shower with it?
The CXS10 is rated IP68— safe for rain, sweat, and hand washing. However, it is not designed for swimming, showering with hot water, or submersion.
IP68 protects against powerful water jets but not prolonged immersion. Remove the watch before swimming, bathing, or sauna use.
How does family remote sharing work? Is my data private?
Family sharing is opt-in and permission-based — the watch wearer must explicitly approve who can view their data.
Once approved, family members can see selected health metrics (BP, HR, sleep, activity) through their own G band app.
Data is end-to-end encrypted in transit and at rest. We are GDPR compliant and never sell or share your health data with third parties.
You can revoke sharing permissions at any time.
