2. What type of watch is the NORTH EDGE ET585?
The ET585 is a high-end ECG health management watch — combining an Amoled Retina screen with ECG detection, intelligent micro physical examination, emotional fatigue detection, blood composition testing, body composition testing, scientific sleep monitoring, and HRV heart health index with risk assessment of arrhythmia.
3. What about the display and the crown?
The ET585 features a 2.04-inch AMOLED Retina full touch screen with a 368×448 resolution, ultra narrow black edges and a screen-to-body ratio of over 93%, a 60Hz refresh rate, 98% Adobe RGB ultra wide color gamut, 178°(H)/178°(V) viewing angle, and accurate color restoration (ΔE<5). The focal rotating crown supports application icon scaling, quick target locking, menu swiping, volume adjustment, and multi-task switching — between squares and circles, see the crown immediately.
4. What about the ECG and HRV functions?
Using high-performance ECG sensors combined with pulse wave atrial fibrillation and premature heartbeat prompts, the ET585 performs ECG collection to achieve early awareness and reminders of risks such as atrial fibrillation through the APP. The APP report shows heart rate, QT interval, HRV, and risk assessment of 16 cardiac conditions (e.g., atrial fibrillation, myocardial ischemia, ventricular hypertrophy, bundle branch blocks, etc.). HRV (heart rate variability) is an important indicator for assessing the impact of neural activity on the cardiovascular system, with Lorenz scatter plot analysis and a heart health index.
*This product is not a medical device, and the measurement data and results are for reference only and not used as a basis for diagnosis and treatment. The ECG function is not applicable to users under the age of 18 and those with known arrhythmias.
5. What about the one-touch micro physical examination?
The 30-second micro physical examination function allows users to detect health indicators based on the watch and obtain physiological parameters such as heart rate, blood pressure, blood oxygen, stress, and body temperature within 30 seconds — with no abnormalities found / 1 abnormality / 4 abnormalities report results.
*This product is not a medical device, and the measurement data and results are for reference only and not used as a basis for diagnosis and treatment.
6. What about blood composition monitoring?
The ET585 measures and analyzes five major items of blood composition: uric acid, total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein, helping you constantly understand the health status of blood components. A personal mode can be set to obtain accurate health data.

7. What about body composition measurement?
The ET585 achieves high-precision body fat BMI measurement — one measurement and results are obtained, with data analysis viewable through the APP. Body fat percentage is the standard for judging obesity and thinness. The report includes basal metabolic rate, bone mass, moisture, fat, protein, muscle, subcutaneous fat, and skeletal muscle.
*This product is not a medical device, and the measurement data and results are for reference only and not used as a basis for diagnosis and treatment.
8. What about blood oxygen monitoring?
Blood oxygen saturation is related to brain and heart health. Real-time blood oxygen monitoring, combined with the analysis and research of sleep apnea syndrome (OSAHS) on the APP, provides a nocturnal hypoxia awakening function to constantly protect your health condition. Key indicators include apnea frequency, blood oxygen concentration, respiratory rate, hypoxia time, and cardiac load.
*This product is not a medical device, and the measurement data and results are for reference only and not used as a basis for diagnosis and treatment. The OSAHS analysis is not applicable to users under the age of 18 and those with known sleep disorders.
9. What about sleep monitoring?
The ET585 provides scientific sleep monitoring that accurately assesses sleep structure and sleep efficiency, identifies and analyzes sleep quality, and supports 24-hour sleep monitoring — assisting users with snoring and identifying respiratory risks during sleep. Sleep data includes total sleep duration, awake time, insomnia, REM sleep, light sleep, and deep sleep.
*This product is not a medical device, and the measurement data and results are for reference only and not used as a basis for diagnosis and treatment.
10. What about blood pressure monitoring?
Based on high-precision sensors, the ET585 achieves a precise blood pressure measurement function, and provides prompts during high and low pressure. You can view the recent blood pressure situation through the APP.
*This product is not a medical device, and the measurement data and results are for reference only and not used as a basis for diagnosis and treatment.
11. What about blood glucose monitoring?
High blood sugar can easily cause hypertension and vascular disease. The ET585 achieves non-invasive real-time monitoring of blood sugar, and a personal blood sugar mode can be set through the APP to truly achieve personal management.
*This product is not a medical device, and the measurement data and results are for reference only and not used as a basis for diagnosis and treatment.
12. What about emotion and fatigue detection?
The 30-second emotion and fatigue function allows users to detect health indicators based on the watch within 30 seconds and conduct a related evaluation of their emotions and stress levels — effectively viewing the current emotional, stress, and fatigue status (e.g., Fatigue 5 Moderate Fatigue, Emotion 2 Stable).
*This product is not a medical device, and the measurement data and results are for reference only and not used as a basis for diagnosis and treatment.
13. What other health functions does the ET585 have?
MET function — energy metabolism equivalent, a commonly used indicator of relative energy metabolism levels during various activities.
Women's Health — real-time recording of menstrual period with menstrual reminder function; the watch sends a reminder the day before predicting the menstrual period.
Respiratory Training — guided breathing training to help you quickly recover under high pressure.
Long Sitting Reminder — set a sedentary time period via the APP to help you always pay attention to your health.
*This product is not a medical device, and the measurement data and results are for reference only and not used as a basis for diagnosis and treatment.
14. Does the ET585 have an SOS function?
Yes. If an accident occurs, users can press the SOS button to make an emergency call and contact their family members for an alarm function. You can add up to 10 contacts to the device and set up to 5 for emergencies. (Note: the ET585 does not support independent communication. The SOS emergency call is based on the Bluetooth call function — Bluetooth call must be connected, the phone and watch Bluetooth must remain connected, and emergency contacts must be pre-set.)
15. What about the sports modes?
The ET585 supports 11 major categories with over 130 different sports modes, and conducts detailed analysis on some sports modes to help you exercise more effectively. Data monitoring and analysis are conducted on the duration, heart rate, distance, and energy consumption during each exercise, giving you evidence-based support during exercise.
16. What about smart connectivity?
After connecting to the APP through Bluetooth, you can: make and receive Bluetooth calls on the watch (answer, hang up, view communication records and contacts), receive smart notifications, control music (select songs, play, switch, pause), check the weather by raising your wrist (hourly and daily forecasts for the week), and use NFC for access control by lifting the wrist. A massive online watch face library — sporty, minimalist, business, healthy — plus DIY custom dials with your own photos.
17. What about the battery and charging?
The ET585 features a 530mAh large capacity battery with ultra long battery life — intelligent daily use for 7–10 days and standby battery life of 30+ days. Charging is by magnetic suction. (After turning on the AOD always-on display function, battery life is shortened to 3 days. Battery data comes from the company's laboratory and may vary with actual use.)
18. Is the ET585 waterproof?
Yes.
ET585 is IP68 waterproof and can handle wind and rain with ease - suitable for daily contact with water, water sports, and shallow water activities such as swimming in swimming pools or beaches. Note: not suitable for diving, hot water showers, hot springs, saunas, or other wading/deep water activities under high-speed water flow.
