Chronex brings compatible heart-rate records, cuffless blood-pressure estimates, estimated sleep patterns and activity data into its companion app. Use the outputs to compare general wellness routines rather than diagnose symptoms or guide treatment.
Chronex can display cuffless blood-pressure estimates for general wellness awareness. These wrist outputs are not a substitute for a validated upper-arm cuff and must not guide diagnosis, medication changes or urgent-care decisions.
Follow the companion-app instructions, touch the sensor and remain still to record the listed ECG wellness waveform. It is not a diagnostic electrocardiogram and cannot detect or rule out a heart attack or another condition. Compare related models in our ECG smartwatch collection.
Wear Chronex overnight to compare estimated sleep duration and stages alongside wrist-based heart-rate trends. Use these outputs for general routine awareness, not to diagnose a sleep or medical condition.
Use compatible steps, estimated calories, distance and activity records to compare everyday routines in the app. These are general fitness and wellness tools rather than medical measurements.
Chronex displays wrist-based SpO₂ and skin-temperature estimates alongside optional menstrual-cycle information in the compatible app. Fit, movement, environment and skin contact can affect sensor outputs.
Do not use these outputs to diagnose illness, determine fever, guide treatment or make urgent decisions.
With a compatible phone paired and within Bluetooth range, Chronex can provide supported call controls through its built-in speaker and microphone. Calling, contacts and voice-assistant features vary by phone, operating system and permissions.
Set up a saved contact in the compatible app, pair Chronex with the phone and test the shortcut in advance. The side button is intended to start a contact call through the paired phone while it remains within Bluetooth range. Compare related options in our smartwatches for seniors collection.

A smartwatch with SOS can make saved-contact access more convenient, but setup and connection limits matter. Chronex is not a substitute for a monitored medical-alert or emergency-response service.
The compatible paired phone must remain within Bluetooth range with the necessary permissions enabled.
Configure the saved contact and test the feature before considering it part of an everyday routine.
The shortcut does not guarantee a connection and does not transmit GPS location.
Chronex includes free tracked shipping and a 30-day return window, subject to the REXQU Returns and Refunds Policy.
Use compatible analogue-style or data-focused watch faces to change how information appears on the 1.43-inch AMOLED. Available designs and customization options can vary by app version and phone compatibility.

This is the most important section on the page, because an SOS button is bought on trust. Here is exactly what happens when it is pressed.
Pressing SOS on Chronex sends an alert and location to the people you added in advance, through the paired phone. There is no monitoring centre, no operator and no dispatcher. If what you need is a professional who answers 24/7 and can send help, that is a monitored medical-alert service and it is a different product. Buy one of those instead, and do not let a watch stand in for it.
The alert travels over your phone’s connection. A flat phone, a phone left upstairs, or no coverage all mean the alert does not arrive. This is true of every consumer smartwatch SOS feature, and it is the single most important limitation to understand before relying on one.
Add the contacts, confirm they actually receive the alert, and have the wearer press the button deliberately once so the first real press is not the first ever. Then keep the watch charged — a flat watch helps nobody. See how SOS buttons work in practice.
The CDC falls prevention guidance and the National Institute on Aging both point to the same things: strength and balance work, a medication review, an eye test, and clearing the rugs and cables people trip over. A button is the last line of defence, not the first.
The ECG waveform is a single-lead trace to save and show a clinician, not a diagnosis — see our ECG guide. Heart rate is the reliable everyday figure; the American Heart Association has the ranges, and battery life for seniors matters because a watch only helps while it is charged and worn.

No. Chronex sends an alert with location to the contacts you have set up in advance, through your paired phone. There is no monitoring centre behind it and it does not dial emergency services. That means it depends on your phone having battery and signal, and on someone seeing the alert and acting. If you need a service where a professional answers around the clock and can dispatch help, buy a monitored medical-alert system — a smartwatch is not a substitute for one.
They solve different problems. A monitored pendant connects to an operator who can send help, which a watch cannot. A watch gets worn far more consistently — including outdoors, at night and in the bathroom, where a pendant often gets left on the side — and it does not announce itself as a medical device. For many families the honest answer is both: the watch for everyday wear and reassurance, a monitored service for genuine emergencies.
Set up a saved contact in the compatible app, pair Chronex with your phone and test the shortcut in advance. The button is intended to start contact calling through the paired phone while it remains within Bluetooth range.
No. Chronex is not a standalone cellular watch. SOS contact calling and ordinary Bluetooth calls require a compatible paired phone within range, an available connection and the necessary permissions.
No. The SOS shortcut is not a monitored emergency-response service, does not guarantee that a call will connect and does not transmit GPS location. Use appropriate local emergency services and a purpose-built device when dependable emergency support is required.
Follow the app instructions, touch the sensor and remain still to record the listed on-demand ECG wellness waveform. It is not a diagnostic electrocardiogram and cannot detect or rule out a heart attack or another condition.
No. Any cuffless blood-pressure output is a general wellness estimate and should not replace a validated upper-arm cuff or medical assessment. Never change medication or delay care because of a watch reading.
Use wrist-based SpO2 and skin-temperature outputs as general wellness trends. Fit, movement, environment and skin contact can affect estimates, which should not be used for diagnosis, treatment or urgent decisions.
Chronex lists 7–10 days of normal use, up to 15 days of standby and about two hours for magnetic charging. Actual results vary with calls, display use, settings and enabled features.
No. The listed IP67 rating is intended for limited splash and dust resistance, not swimming, showering, diving or deliberate submersion. Water resistance can reduce over time.
Chronex is listed for iPhone with iOS 8.0 or later and Android 4.4 or later over Bluetooth 5.1. Compatibility varies by phone, operating-system version and permissions. No subscription is listed as required for the advertised features.
