The Health Watch That Dresses for Dinner.
Infinity Pro is a round smartwatch built around a bright 1.56-inch 480×480 AMOLED display and a zinc-alloy case.

Infinity Pro pairs a classic circular watch shape with a high-resolution AMOLED display and a broad set of wellness, communication and everyday utility features.
Record a consumer wrist ECG and review the waveform and supported rhythm information in the companion app for personal wellness awareness.
A quick wellness check brings together heart rate, blood-pressure estimates, blood-oxygen information and temperature-related data for trend awareness.
A crisp round display in a zinc-alloy case that reads as a classic watch, not a gadget.
A built-in LED adds practical light, while the SOS feature can contact configured people when the required setup and connection are available.
Dual-mode Bluetooth 5.3 calling with an intelligent voice assistant and music control.
Estimated sleep stages, stress-related wellness trends and cycle tracking in the app.
Infinity Pro can capture a wrist ECG waveform and display supported ECG- and HRV-related information in the companion app. Save the recording for your own reference or use it as background information when discussing concerns with a healthcare professional.
Infinity Pro is not a clinical 12-lead ECG and does not diagnose heart conditions.
The Health Glance feature can bring several wrist-based wellness readings together in about a minute, including heart rate, blood-pressure estimates, blood-oxygen information and temperature-related data, so you can compare your own trends over time.
For general wellness awareness only. Use validated medical devices when clinical measurements are needed.
The optical sensor can collect heart-rate information through the day when background tracking is enabled, giving you a personal trend line across rest, activity and everyday routines.
Designed for awareness and conversation with your physician — not for diagnosis.
Automatic sleep tracking estimates sleep and wake periods and shows light, deep and wake-stage patterns in the app, helping you compare your own nightly routine over time.
Infinity Pro takes blood-oxygen readings from the wrist and charts them in the companion app beside your heart rate, sleep and activity — wellness trend information for spotting change across weeks, not a clinical measurement.
For general wellness and fitness awareness — not a medical device.
Use supported stress-related wellness readings for personal trend awareness, while cycle tracking keeps period and cycle information alongside other everyday health-and-fitness data in the companion app.
The high-brightness LED gives you practical light for dark paths, car parks and power cuts. The SOS feature is designed to contact configured people when the required watch, phone, network and battery conditions are available.
Infinity Pro is not a medical-alert service and should not be your only emergency-contact method.
The zinc-alloy case and circular bezel give Infinity Pro the look of a traditional round watch, while the 1.56-inch AMOLED, Bluetooth calling and voice-assistant support add modern smartwatch convenience.

Infinity Pro is designed for people who want smartwatch features without giving up the appearance of a traditional round watch.
The round case and AMOLED display give Infinity Pro a dress-watch appearance while keeping calls, notifications and wellness trends on the wrist.
The built-in LED gives you a small light source directly on the watch for practical everyday situations.
Use the ECG, heart-rate, HRV, sleep and other supported features to compare your own trends over time rather than relying on a single wrist reading.
Classic analog for the office, data-dense for training, minimal for dinner — swap round dials from the app and the AMOLED makes each one glow.
Infinity Pro targets the round AMOLED smartwatch shopper, while its ECG, flashlight and wellness features connect naturally to our specialist guides and categories.

The shape decision is mostly about what you want the watch to look like on a wrist, but a few practical things do follow from it.
A square screen shows more lines of text; a round one looks like something you would have worn anyway. If the watch has to work with a shirt cuff and a dinner table as well as a workout, round is usually the answer — and a watch you are happy to wear everywhere collects far more complete data than one you take off at 6pm.
Pixel density is what decides whether small text is crisp or fuzzy, and a round display wastes none of its area on corners you never look at. It is the difference between glancing at a reading and squinting at one.
Infinity Pro takes a single-lead trace from your wrist and a fingertip. That is one view of the heart’s electrical activity, not the twelve-lead recording a clinician uses, and it does not interpret anything. Save the traces and show them to someone qualified — our ECG smartwatch guide and what a watch can say about AFib cover the limits, and the American Heart Association on arrhythmia has the background.
It runs the sensors in sequence and gives you several readings at once. Useful for building a habit and a baseline; not a substitute for a check-up, and every number in it carries the usual optical-sensor caveats about fit, movement and circulation.
The LED beam is genuinely handy for close work in the dark. SOS alerts contacts you set up in advance through your phone — it is not an emergency service and does not dispatch help. Set the contacts up before you need them. The CDC activity guidelines are the daily target the tracking works towards.

Neither is better — they fail differently. A square screen fits more lines of text and suits list-heavy interfaces; a round one looks like a conventional watch, which matters if you want to wear it with a suit or to dinner. The practical argument for round is that people keep wearing it in situations where a square sports watch comes off, and a watch on your wrist collects data that a watch in a drawer does not.
Less than you would think. A round panel uses all of its visible area, whereas a square screen has corners that most watch faces leave empty anyway. Where round genuinely costs you is long lines of text, such as reading a full message — you get fewer words per line. For glanceable readings, which is what most people use a watch for, it makes no practical difference.
Infinity Pro uses a circular 1.56-inch AMOLED display with a 480×480 resolution inside a zinc-alloy round case, giving it a traditional watch shape with modern smartwatch features.
The product information lists Android 5 and newer and iOS 10 and newer through the H Band app over Bluetooth 5.3. Compatibility can vary with phone, operating-system and app updates.
No. Infinity Pro records a consumer wrist ECG for personal wellness awareness. It is not a clinical 12-lead ECG and does not diagnose arrhythmia or other heart conditions.
No. Treat the wrist-based blood-pressure feature as a wellness estimate. Use a validated upper-arm cuff and professional medical advice when accurate clinical measurement matters.
A high-brightness LED is built into the watch case for practical light and a flashing visibility mode.
The SOS feature is designed to contact configured people when the required setup and connection are available. It depends on device settings, compatible phone or network conditions, signal and battery, and it is not a medical-alert service.
The watch is listed as IP67 rated for everyday exposure such as rain and sweat. Keep it out of the pool and shower unless current product documentation specifically states otherwise.
There is no required monthly REXQU subscription for the advertised watch features. Companion-app requirements can change over time.
