9 Best Smartwatches with Blood Sugar Monitor: (2025 Guide & Reviews)

Last Updated on August 7, 2025 by Luis Cooper

Individuals with diabetes can greatly benefit from using smartwatches to support a healthy lifestyle.

You can use these tools to control your eating plan, heart rate, caloric intake, or even oxygen levels.

Knowing these strategies can help diabetic individuals control their blood sugar levels.

Dexcom analyses the patient’s blood glucose level and sends the information to their watches or even smartphones. 

Smartwatches can greatly benefit people with diabetes; however, there are many options on the market.

Due to this, determining which smartwatches are best suited for treating diabetes can be challenging.

The top smartwatches for diabetes management are listed below to help you make an informed decision.

We’ve conducted an extensive study to shorten our list.

Which are the Best Smartwatches with Blood Sugar Monitor?

Here are my recommended top 10 Best Smartwatches with Blood Sugar Monitors:-

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 cut down signal noise, making the 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.

I recommend this for anyone who wants real health tracking with technical improvements that make a difference.

2. SAMSUNG Watch 8: (Best Watch for Measuring Blood Sugar + More Health Insights)

On my friend’s recommendation, I upgraded to the new Samsung Galaxy Watch 8  mainly to track my sugar levels and keep better tabs on my overall health.

After years of painful finger-pricks and lab visits, I was looking for something smarter and less invasive.

This watch still pairs with tools like Dexcom for blood glucose monitoring, but the added health metrics took me by surprise, especially things like antioxidant level tracking and vascular load analysis, which I never thought I’d care about until I started using it.

And yep, the built-in GPS tracking is solid.

I’ve used it on runs, hikes, and even casual walks, and it’s extremely accurate.

WHAT DO WE GET FROM THESE?

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.

Conclusion:

If you’re dealing with diabetes or just want a powerful wellness companion, this is hands down the best Samsung smartwatch right now.

It’s painless, personalized, and packed with features that actually matter.

You still get accurate Dexcom CGM pairing — but with way more health insights on top.

Honestly, it feels like the smartest watch Samsung’s ever built.

My doctor recommended that I monitor my glucose levels.

I decided to get myself a smartwatch rather than a blood test every day.

After extensive research, I discovered the Apple Ultra Watch 2, which enabled me to monitor my blood sugar using a Dexcom CGM.

Without any needles, it allowed me to test my sugar level.

One of my friends is a diabetic patient who needs to check his glucose levels every week.

Getting checked by the test is quite expensive and painful.

Monitoring of the Watch: 

The Huawei Watch 4 pro has hardware to monitor blood pressure, blood oxygen, and body temperature, which are crucial in detecting high glucose warnings.

Instead, they track other health metrics, such as heart rate, sleep, and activity levels, that can be used to infer blood sugar levels.

High blood sugar levels can lead to a decrease in heart rate variability.

6. Google Pixel Watch: (Best Heart Rate Tracking Smartwatch)

I was looking for an inexpensive smartwatch with a blood sugar monitor.

As a fitness trainer, I need to keep checking my sugar intake.

And this is the best way to monitor sugar levels.

One day, while scrolling through my feed, I came across the Google Pixel Android smartwatch, and after reading such remarkable reviews, I decided to order it.

I tried and tested it for a month; this was the best device with a blood sugar monitor.

The monitor functions well and provides accurate results.

It does not require physical blood tests.

Instead, you can download a dedicated pixel watch app to pair the watch.

You can swipe up from home to see your notifications and down to access quick settings.

The customizable apps are now available on both the left and right of the Home Screen, looping back to your watch face when you reach the end in either direction.

Furthermore, each watch face has customizable elements, letting you choose between Arabic numerals or unlabeled dashes and pick your favorite.

You can also customize every watch face according to your preferences. 

Advanced Health Sensors:

The Pixel Watch can track your activity, workouts, and sleep, which can be easily imported into the Fitbit app.

However, there aren’t any standout features that are exclusive to the Pixel Watch.

The experience is similar to what you would find on other devices, for better or worse.

You can choose from about 40 different exercise types to manually track workouts; if you don’t choose one before your workout starts, Fitbit will broadly classify it with labels like walking or general “activity” once you’re finished.

This stunning smartwatch helps you monitor your sugar intake without the need for needles or blood samples.

WHAT DO WE GET FROM THESE? 

Design:

I love the design of the Forerunner 245.

It’s incredibly user-friendly and comfortable, and it weighs only 38.5g.

With the standard five-button setup, navigating menus and controlling the device while on the move is a breeze.

The watch’s 240 x 240 full-color transflective screen offers clarity in all lighting conditions.

It’s the same high-quality display found on Garmin’s other high-end watches, giving the impression that the Forerunner 245 is a premium device.

Activity and Sports Tracking:

The Forerunner 245 features several new sports modes compared to its predecessor, with the most notable additions being pool swimming and strength training.

However, the watch is waterproof to 50m and provides a range of swim-specific stats.

Although it is a sports watch, the Forerunner 245’s everyday activity tracking is also solid, first and foremost.

9. SAMSUNG Galaxy 3: (Best Smartwatch with Advanced Health Monitoring Using a CGM Device)

I enjoy wearing watches and like to switch them out occasionally, so at the start of this year, I wanted to do the same because the watch I was wearing was getting old since I had worn it for 1.5 years.

I intended to get a well-known watch that is among the best smartwatches with blood sugar monitors, easy to use, and stylish.

Features:

Design:

The tactile bezel was both useful and enjoyable during my initial evaluation of the Samsung Galaxy Watch mechanism.

Swiping or attempting to push at the round display using the finger was not as effective as spinning the dial, which worked nicely with all side buttons.

The bezel stands up the second or third time around and feels considerably better as Samsung makes the Galaxy Watch 3 thinner.

The new Galaxy Watch is 15% lighter, 14% slimmer, and 8% tinier compared to the original.

However, compared to my Apple Watches, the 41mm, 1.7-ounce Mystic Bronze version I examined seems bulky.

It looks less similar to a high-tech watch and more like a conventional one.

The Samsung Galaxy Watch 3 stands as a fashionable piece, although I might forgo my Apple Watch for a fancy meal or a date night.

Even better, the Samsung Galaxy Watch 3 features authentic leather bands that complement the case’s color and lend it a more upscale appearance.

Performance And Display:

The Samsung Galaxy Watch 3’s 360 x 360-pixel display is clear and sharp enough to be visible in bright sunshine, and it is constantly on.

I’ll be honest: Apple Watch issues make me anxious.

The Galaxy Watch 3 has 40 complications and 80,000 distinct watch faces, which makes things much easier for me. 

The numerous menus on the Galaxy Watch 3 are highly customizable and feature practical applications.

The bezel makes navigation simple, and I used the two keys to reach the desired location.

What Makes It Best:

The Samsung Galaxy Watch 3 can monitor 40 different activities, including workouts, etc.

Seven of these can be recorded automatically, so you won’t necessarily need to choose the type of activity you’re doing in advance.

The Galaxy Watch 3’s built-in GPS precisely determined my regular course.

With an ECG monitor that has received FDA approval, the Galaxy Watch 3 can detect atrial fibrillation symptoms.

In a congested smartwatch industry, the Samsung Galaxy Watch 3 distinguishes out.

Samsung was able to build an equilibrium between fashion and fitness tracking.

Although there are many fashionable smartwatches and great fitness trackers available today, this watch stands out the most.

Conclusion:

The Samsung Galaxy Watch 3 features a rotatable bezel, ECG tracking, and fall warning capabilities.

It is currently the best, most versatile Android smartwatch available.

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 almost similar in appearance to the classic Venu 2, the Garmin Venu 2 Plus has a 43mm casing, as opposed to 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 additional components of the modern watch.

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 constantly vary according to how you utilize the watch’s different functionalities, 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 a maximum of 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:

Including a mic is the main distinction between Venu 2 and Venu 2 Plus.

As long as your smartphone is within Bluetooth range, you can use voice assistance on your phone to place and receive calls.

During my tests using the watch linked to an Android smartphone, Google Assistant could interpret my queries without any issue because of the superb sound clarity from 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:

Is the Apple Watch capable of detecting blood sugar levels?

The Apple Watch can detect blood sugar levels. To display glucose data on the watch, you will need a compatible app and a Continuous Glucose Monitor (CGM), such as the Dexom G6 and G7.

Do blood glucose watches work? 

Watches that measure blood glucose need to be more accurate. They can only display blood glucose levels measured by an external continuous glucose monitoring (CGM) system. The watch’s accuracy depends on the accuracy of the CGM system it is linked to.

What wearable technology monitors blood sugar? 

These devices utilize tiny sensors to examine blood glucose and body temperature through the interstitial fluid without collecting blood. A CGM system takes readings regularly and sends them to your smartphone via a mobile app.

Is it possible to measure blood sugar levels with a Samsung watch?

Likewise, the Samsung watch measures blood sugar levels, but an app and CGM device are required to display the information.
