1. HUAWEI GT 5 Pro: (Powerful Health Companion with Premium Feel)
Last month, I started feeling like I needed a break — not from work, but from not paying attention to my sleep, heart, and overall health.
I’ve used fitness trackers before, but nothing that gave me real, useful health data in one place.
That’s when I tried the Huawei Watch GT 5 Pro, and honestly, it felt like leveling up.
WHAT DO WE GET FROM THESE?
Durable Construction:
Huawei knows how to build things that last.
The GT 5 Pro is built with a redesigned module that feels solid on the wrist but never heavy.
The titanium case and sapphire glass make it feel premium and handle rough use without a scratch.
The strap fits comfortably and doesn’t irritate the skin during workouts or sleep.
The crown and buttons are responsive, and the watch looks sleek — something you’d actually want to wear every day, not just to the gym.
Monitoring of the Watch:
This is where the GT 5 Pro shines.
The multi-region optical path and glass-darkening tech help reduce signal noise, making heart rate accuracy surprisingly solid — even during HIIT or runs.
And it’s not just about the basics.
This watch provides sleep analysis, sleep breathing awareness, and sleep stages, helping me identify breathing disturbances and clearly see my fall-asleep and wake-up times.
What really impressed me was how fast it gathers health metrics.
Within 15 seconds, I could get a snapshot of my blood oxygen, respiratory rate, arterial stiffness, and ECG — it’s like having a mini-lab on your wrist.
The Huawei Health app shows historical graphs in an Apple Health-style layout, and though some of the cards feel a bit “meh,” the actual body biomarkers and averages give helpful context and baselines.
It also lets you track stress, and it uses HRV data through a proper calibration process with 12 questions.
The whole algorithm feels smarter than your typical smartwatches.
Conclusion:
The Huawei GT 5 Pro feels like it’s not trying to be flashy — it’s just quietly excellent.
If you’re serious about understanding your sleep, heart, or even arterial stiffness, this is the kind of watch that delivers solid insights without overwhelming you.

Built to Last (and Look Good Too):
The Galaxy Watch 8 keeps the durable design Samsung is known for, with a slim aluminum case and that sapphire crystal glass face.
It feels premium but isn’t too flashy.
The display is stunning — seriously, 3,000 nits of brightness makes it readable even under harsh sunlight.
What really impressed me was how smart the watch actually feels.
It goes beyond tracking — it guides.
With AI-powered coaching, detailed sleep reports, and advanced wellness tracking, it’s more like having a health assistant on your wrist.
Oh, and it still supports the Dexcom CGM device, so blood sugar monitoring remains part of the package, especially helpful for anyone managing diabetes.
New Sensors & Smarter Insights:
Beyond the usual fitness stuff, Samsung went further with bioelectrical impedance analysis (BIA), heart rate monitoring, SpO2, and even skin temperature sensing.
I ran a 12-minute test, and the watch built a custom fitness plan just for me.
The Running Coach gave me real-time suggestions during my jog, which felt weirdly helpful — almost like someone whispering coaching tips in my ear.
I also tested the new antioxidant level checker.
All I had to do was take the watch off and hold my thumb on the sensor for five seconds.
My first score? “Low.” Time to eat more persimmons, I guess.

4. Apple Watch Series 11: (Best Smartwatch as a Blood Sugar Companion)
The Apple Watch Series 11 does not measure blood sugar by itself.
What makes it one of the best choices for people who want on-wrist glucose info is how well it works with real Continuous Glucose Monitors (CGMs).
With direct CGM connections (where supported) and fast alerts on the wrist, the Series 11 becomes a very useful companion display—fast to glance at during workouts, driving, or sleep—while the actual glucose sensing is still done by an approved CGM device.
How it works: Companion display vs sensor
Smartwatches fall into two categories for glucose:
- True glucose devices (FDA-cleared CGMs) that use an under-skin sensor and report real glucose numbers.
- Watch displays that show data sent from those CGMs or from the phone app.
The Apple Watch Series 11 is in the second group.
It shows CGM values, trends, and alarms from supported CGMs (for example, Dexcom G7’s direct-to-watch feature), so you can glance at numbers and trend arrows without opening your phone.
That convenience matters a lot in daily life, but remember: the watch is displaying CGM data — it is not sensing glucose itself.
Why Series 11 stands out for glucose monitoring:
Direct CGM integrations are real now. Dexcom announced direct-to-Apple-Watch support for G7, which removes the need to keep your phone physically close for basic alerts and readings. That lowers friction and makes wrist checks genuinely convenient
Stable platform and fast alerts. watchOS and Apple’s hardware keep notifications and haptics reliable, so low/high warnings reach your wrist with minimal delay. Reliable haptics are essential for safety when you can’t look at the screen.
Ecosystem and data export. Apple Health makes it straightforward to export or share CGM charts with clinicians if you need them for diagnosis or adjustments. Apple’s seamless backups and privacy controls are useful when you manage medical data.
Safety & regulatory reality:
The U.S. FDA has made a clear and important statement: no smartwatch or smart ring is authorized to measure blood glucose by itself.
That means any device claiming needle-free glucose readings should be treated with caution.
Use only FDA-cleared CGMs (or your glucose meter) for medical decisions.
The Apple Watch + CGM route is safe only because the CGM is the sensor and the watch is a display/alert device.
Where Apple leads, and where others catch up:
Apple Watch (Series 11): strong direct CGM support (Dexcom), best iPhone/Health integration, reliable haptics, and UI. Great for iPhone users who want a tidy on-wrist view and quick alarms.
Google / Wear OS watches (Pixel Watch 4, Pixel Watch 3/5): good third-party app support (Gluroo, others) and improving battery life, but CGM direct support varies by vendor and often still relies on phone bridging. On Android, they’re useful, but experience depends on the CGM app ecosystem.
Samsung watches: can show CGM notifications via phone apps; hardware and ecosystem tie-ins vary by region and vendor. Some CGM companies prioritize Apple first.
What to expect:
Night checks and alarms: When a CGM is paired directly, the Series 11 can vibrate and show trend arrows while you sleep. That gives fast cues for potential hypos overnight. In real tests from multiple sources, direct watch alerts reduced the friction of waking and checking the phone.
During exercise: glanceable glucose numbers on the wrist help you decide whether to eat carbs mid-session. Trend arrows add context beyond a single number.
Accuracy: accuracy depends entirely on the CGM sensor and its calibration. The watch does not change the sensor’s precision; it only displays what the CGM reports.
Set up tips: Get the most from Series 11 + CGM
- Use an approved CGM (Dexcom G7, Abbott Libre, etc.) and install its latest app on your iPhone first. Confirm the app supports direct watch display or reliable notifications.
- Enable direct watch pairing if your CGM supports it (Dexcom G7 has direct-to-watch capability). This avoids relying on phone proximity for basic readings.
- Set strong haptics and loud alerts for overnight lows. Test alerts while awake to make sure you’ll feel them during sleep.
- Verify numbers first. Cross-check watch values against your CGM phone app (and a fingerstick when needed) in the first few days to ensure everything is routed correctly.
- Save and share suspicious patterns with your clinician; export CGM/Health data for meaningful discussion.
Conclusion:
If you or someone you care for uses glucose-lowering medication, never act on a non-approved device or unconfirmed reading.
Use the CGM/phone as the source of truth for dosing.
Treat the Apple Watch Series 11 as an excellent, convenient display and alert system that reduces friction and speeds awareness, but not as a replacement for approved medical devices.

9. Google Pixel Watch 4: (Best Smartwatch with Advanced Health Monitoring Using a CGM Device)
BODY:
The Pixel Watch 4 is a great Wear OS smartwatch for people who want a modern watch that can show continuous glucose data from a proper CGM system.
Important point first: the Pixel Watch 4 does not measure blood sugar itself.
There is no non-invasive glucose sensor built into the watch.
Instead, the Pixel Watch 4 works as a companion display for FDA-cleared CGM systems (Dexcom, FreeStyle Libre, and others) through phone apps and third-party Wear OS apps/watchfaces.
That makes it very useful for quick checks on the wrist, but you must rely on an approved CGM or meter for dosing and medical decisions.
BATTERY:
Google improved battery life, and the new Pixel Watch 4 can last a full day with normal use.
If you enable continuous CGM readouts on a watch face or run background apps that poll the phone, expect the battery to fall faster than a basic watch face.
In practice, a full day plus some spare hours is realistic; heavy always-on displays and active CGM complications shorten that window.
Check your settings if you want multi-day CGM visibility.
How glucose data reaches the watch:
There are two common ways glucose shows up on the Pixel Watch 4:
Official CGM app + phone notifications. Many CGM systems send alerts and summary notifications from the phone to your watch. That gives quick warnings for highs and lows, but often needs the phone nearby. Dexcom and FreeStyle Libre both provide mobile apps that route alerts to smartwatches via the phone.
Wear OS companion apps and watchfaces. Third-party tools like Gluroo or watchfaces designed for CGM (for example, Gluroo’s Wear OS ecosystem) let you show real-time glucose values and trends directly on a Pixel Watch face, provided the phone app is connected to the CGM. These tools expand what you can see on the wrist but rely on the phone and the CGM backend to feed accurate numbers. Expect occasional compatibility quirks depending on the CGM model and OS versions.
HEALTH: (what this setup actually gives you)
- Real-time glucose values and trend arrows on the watch face for fast checks while you are working, exercising, or driving.
- Alerts for high and low glucose are delivered as haptics and on-screen notifications when your CGM sends an alarm.
- At-a-glance history with simple trend lines or small charts on some watchfaces so you can decide whether to pause exercise, take carbs, or check with your phone.
Remember: these are visual and notification tools only. The watch is a viewer and alert device. For insulin dosing or clinical choices, use your CGM’s official reader or phone app and follow medical advice. The FDA explicitly warns people not to trust watches or rings that claim to measure glucose noninvasively.
How to use Pixel Watch 4 as a glucose companion:
- Pick a supported CGM. Dexcom and FreeStyle Libre have established mobile apps and follow-up systems that can send wrist alerts. Confirm the CGM model and app compatibility for Android and Wear OS.
- Install the phone app first. Get the official CGM mobile app running and sharing notifications. Many watch solutions need the phone app as the primary data source.
- Try a dedicated watchface or third-party app (Gluroo, SugarPixel, etc.). These can place glucose values and trend arrows directly on your watchface for instant visibility. Expect occasional setup fiddles; read the developer help pages.
- Set strong alarms and haptics. Wrist vibration is helpful when you can’t look at your phone. Test alarm loudness and vibration placement.
- Verify accuracy on your first days. Cross-check watch values with the CGM phone app and occasional fingerstick meters if you use them, especially when using third-party integrations.
WHY PIXEL WATCH 4 IS USEFUL:
Apple Watch has tighter, sometimes more direct support for some CGMs (Apple Watch can receive direct Dexcom G7 readings in some setups).
On Wear OS, the situation has historically been more fragmented, but it is improving.
Pixel Watch 4 benefits from Wear OS apps like Gluroo and from Google’s updates that improve watch performance and battery life.
If you want a modern Wear OS watch that can display CGM data cleanly and you use Android, the Pixel Watch 4 is one of the best wrist options today — as long as you accept the companion role and pair it with an approved CGM.
SAFETY & REGULATORY REMINDERS:
The FDA warns consumers not to buy or use smartwatches or rings that claim to measure blood glucose without approved sensors. Never rely on a watch alone for medical dosing.
If a gadget promises needle-free glucose readings, treat it skeptically and check FDA approvals.
Use CGM readings and watch alerts as decision support, not as the sole source for critical insulin or treatment decisions. Confirm with your official CGM app and follow clinical guidance.
SPECS:
| Feature | Pixel Watch 4 (high level) |
| OS | Wear OS 6/5+ with Pixel optimizations and Gemini features. |
| Display | Domed Actua 360, larger and brighter than previous Pixel watches. |
| Battery | Up to multiple tens of hours depending on use; active CGM watchfaces reduce runtime. |

| CGM support | Works as companion display for Dexcom, FreeStyle Libre, and others via phone apps and third-party Wear OS apps like Gluroo. Compatibility varies by CGM model and app. |
10. Garmin Venu 2 Plus: (Best GPS Smartwatch with Blood Sugar Monitor Using Dexcom G6)
I was looking for a watch with my friend before going on a trip to the Maldives, so I came across this watch.
After reading its specifications, I knew I had to buy it.
It offers all the features I was hoping for.
The best watch with blood sugar monitors and other important functions is, without a doubt, this one.
Features:
Design And Performance:
Although similar in appearance to the classic Venu 2, the Garmin Venu 2 Plus has a 43mm casing, compared with the original watch’s 40mm and 45mm cases.
It strikes an excellent balance between size and comfort for smaller wrists, being spacious enough to accommodate the modern watch’s additional components.
Like the Venu 2, the Venu 2 Plus has a high durability of water rating of 5ATM, which qualifies it for bathing and swimming but does not make it suitable for diving or fast-paced watersports.
The Venu 2 Plus’s touchscreen AMOLED screen is vibrant, high-resolution, and responsive.
Although there is an always-on mode, the battery life is shorter.
Battery Life:
The battery life will vary depending on how you use the watch’s different features, especially SpO2 and Global Positioning.
The watch can operate in smartwatch settings for up to nine days, power-saving mode for up to ten days, Navigation and music for up to eight hours, or GPS-only for 24 hours.
I recorded one workout routine while using the Venu 2 Plus, and I discovered that the charge depleted at a pace of about 10% each day, which is higher than the claimed figures and admirable for a potent AMOLED smartwatch.
What Makes It Best:
The main distinction between Venu 2 and Venu 2 Plus is the inclusion of a mic.
As long as your smartphone is within Bluetooth range, you can use your phone’s voice assistant to place and receive calls.
During my tests using the watch linked to an Android smartphone, Google Assistant could interpret my queries without issue, thanks to the superb sound clarity of the mic.
In addition, even when I wasn’t exercising, I found myself using Google Assistant far more frequently than I would normally because it was convenient to have it practically on my wrist.
Conclusion:
With its inbuilt voice assistance and fitness functions, the Garmin Venu 2 Plus is among the best smartwatches and beats its competitors in the market.
FAQs:
