It’s 100 m waterproof and has customizable action buttons for quick physical control over different functions.

3. SAMSUNG Galaxy Watch 6: (Syncing your CGM Device with your Smartwatch)

Features:

Bigger Display: 

Regarding smartwatches, looks are as significant as their functions since they can be worn every day.

Talking about aesthetics, the Galaxy Watch 6 has a lightweight, minimal design. 

As we have reviewed its predecessors, it’s pretty tricky to differentiate, but the Galaxy Watch 6 has a thinner display edge and a large screen. 

The Watch 6 comes with a sharp and colorful AMOLED touchable screen with an always-on feature.

The small size has a 1.3-inch display, while the big size has a 1.5-inch panel. 

Thanks to enhancements in display real estate, icons are shown huge on the display, and graphics are stretched closer to the bezel.

Plus, the Watch Six now offers six font sizes. 

The black screen on the border is less observable, but it makes a discrepancy when you use a watch face with a background.

If your watch face has a black background, the screen border looks like an attachment of the display. 

Battery Life: 

Unfortunately, Samsung has taken a step back in battery life for the latest versions due to the large and brighter display. 

The Watch 6 has a bigger battery than the old models.

At the same time, it has a short battery life of 40 hours on a charge.

That’s a 20% drop from its predecessors, a disappointing downgrade. 

You must know that Samsung’s stated run times exceed real-world battery life performance.

When I was testing it, the Galaxy Watch 6 only offered 22 hours of battery life on a charge, everyday use, and always on display.

I tested it two times for cross-checking and got the same results.

Switching off the always-on display only increased the battery life to 28 hours. 

The Watch 6 needs 70 minutes to get fully charged. Samsung stated that eight minutes of charging is enough for eight hours of sleep tracking. 

The watch six also offers a power-saving mode for when its battery is draining.

When my watch has less than 10% battery with 90 minutes of remaining power, it said the power-saving mode can only give 15 minutes of additional life.

The power saving mode is always on display, which lessens CPU speed and limits the background process. 

Specs:

Brand	Samsung
Model number of the product	SM-R940NZKAXAA
Model name of the item	Samsung Galaxy Watch 6
ASIN	B0C797946T
Batteries	1 lithium-ion batteries required.
Dimensions of the product	1.5 x 2.5 x 11 inches
Connectivity feature	Bluetooth, WiFi
Weight of item	33.3 Grams
Size	Standard
Compatible devices	Smartphones

4. Garmin Fenix 7: (Dexom G7 Compatible with Garmin Smartwatch)

Features:

Design: 

We tested the Garmin Fenix 7, which combines the advantages of sunlight-harvesting power glass with robust crystal. 

It has a graphite gray titanium case and a black silicone strap with different colors.

The silicone band is an excellent choice for sports and is easy to clean, but you can also choose a watch with leather and woven straps for everyday use. 

This watch uses QuickFit bands by Garmin that are released from the case housing by pressing down the plastic clip.

They are easy to swap but are not changeable with old-style bands, which are removed just by pushing the pin.

The Garmin 7 weighs 73g with a silicone strap attached. 

Its solar is the same as the Fenix 6, which comes 72g with its strap and 49g without it.

It’s excellent that Garmin keeps the weight consistent while increasing battery life and improving display technology. 

Battery Life: 

Battery life has always been a central point for buyers, and Fenix 7 delivers it all.

Firstly, it’s essential to note that the life of every watch will depend on the size of the battery, whether it’s a solar cell or the size of the cell. 

The Fenix 7 we tested has a Garmin power glass that injects energy throughout the day to keep the watch’s battery in note.

You’ll need the watch, but the solar cells extend battery life. 

You can’t only charge the watch through solar charging, but it also reduces battery drain.

You can’t leave the watch in the sun only and expect it to get charged fully.

The charging depends on the usage of the watch and the sensors you enable. 

Functions: 

The Fenix 7 comes with advanced sensors that high-end smartwatches have.

SpO2 monitoring works continuously during the night or spot-checking.

You will also see a feature from Fenix 6 that if you move your wrist too much while the watch takes SpO2 reading. 

While traveling, the Fenix 7s GPS tracking and mapping work impressively.

The watch recorded a pre-measured 5km test route within 50m, making it the most accurate watch we tested. 

The Fenix 7 works for everyday navigation, minimizing the need for a mobile device that is visible in a place where it could be stolen.

This watch by Garmin highlights points of interest, including stores or cafes.

It’s excellent and enhances the Fenix 7 as a watch for everyday use. 

So, if you need a set of watches, you’d have to pay for and download them via the Garmin Connect app.

The Fenix 7 has a pre-installed set; users can download their packs through the watch using Map Manager. 

The touch display makes panning across maps quicker than buttons, though the MiP display doesn’t refresh like the AMOLED display, resulting in smooth scrolling and blue-tinged backlight.

Brand	Garmin
Model number of the product	010-02540-00
Model name of the item	Garmin Fenix 7
ASIN	B09NMJMXS1

5. Google Pixel Watch 2: (Continuous Glucose Monitoring on your Smartwatch)

Features:

Accurate Health Insights: 

The Google Pixel watch has three advanced sensors to give you insights into your health.

With a unique AI heart rate algorithm, new heart rate sensors with LEDs generate more accurate results.

It’s 40% more precise for heavy activities like HIIT, rowing, and spinning.

This means you get accuracy in health metrics from burned calories to daily readiness score. 

This also has been brought up with a body response feature powered by a cEDA sensor.

This new sensor can detect signs of stress using a learning algorithm incorporating HRV, HR, and skin temperature.

It will send you notifications when it picks on physical indicators of positive and negative stress, including body response features.

It will even reflect on how you feel at that time and take action to decrease anxiety.

Reflecting on these features helps you monitor patterns to detect stress and plan. 

Improved Fitness Tools: 

It’s convenient to train with Pixel watch 2.

The advanced heart rate zone coaching and pace training functions can help you achieve your workout goals, like notifying you of heart rate changes during high-intensity workouts or feedback on your pace goals.

Also, auto workout start and stop notifications are available for seven exercises, including cycling or running, to help you stick to your schedule.

6. Dexcom G7 Sensor, Device: (Best Smartwatches Compatible with Dexcom G6/G7)

Features:

Accuracy:

The mean absolute relative difference is 8.2% for adults and 8.1% for kids.

This creates a standard in the CGM market and is better than its predecessor.

G7 creates the glucose values in 15% of lab values. 

Smaller Sensor: 

You don’t have to attach a transmitter to the sensor; the transmitter is built into the sensor.

The sensor filament is shorter.

It inserts perpendicular to the skin, leading to a decrease in errorness. 

Warmup Timer:

The warmup timer is less, which is only half an hour.

For those who want to decrease the warmup timer to zero, you must place a new sensor on the skin half an hour before the previous one expires. 

Customization: 

There are different ways to customize high or low alerts to make them more actionable.

The user can set thresholds for beginners when rise and fall notifications occur.

If the glucose is decreasing fast, the user can set an alarm to happen if this happens.

It’s also possible to set high alerts if the glucose is increased for a specific period.

This way, glucose increases right after having a meal and doesn’t trigger useless alerts. 

Specs:

Brand	Dexcom
Type of the product	Continuous glucose monitoring
Model name of the item	Dexcom G7 sensor
Glucose range	40-400 mg/dl
Data transmission	Every 5 minutes
Alerts of the product	Customizable alerts
Connectivity feature	Bluetooth
Weight of sensor	8 grams
Size	Standard
Wearing duration	Upto 10 days

7. Dexcom G6: (Device for Continuous Glucose Monitoring)

Features:

How it Works:

 A small sensor wire is put under the skin of the arm or waist that uses an automated applicator to observe blood sugar levels.

The sensor wire is set with a sticky patch.

The sensor calculates glucose, that is, blood sugar in the fluid between cells relatively more than glucose found in the blood. 

• A transmitter is connected to the sensor that transfers data wirelessly in a few minutes. 
• A receiver is also attached to a monitor that shows glucose levels and trends. 

Advantages: 

The Dexcom G6 helps see directions in blood levels even if the monitoring is not accurate.

CGMs can show spikes and dips in glucose when it’s not suitable to detect sugar levels better. 

It decreases the need for different finger picks that are painful and hard to manage primarily. 

While testing, I noticed it helps to clarify the effect of diet and workout on blood sugar levels.

Specs:

Brand	Dexcom
Type of the product	Continuous glucose monitoring
Model name of the item	Dexcom G6 sensor
Glucose range	40-400 mg/dl
Data transmission	Every 5 minutes
Alerts of the product	Customizable alerts
Connectivity feature	Bluetooth
Weight of sensor	8 grams
Size	Standard
Wearing duration	upto 10 days

Conclusion:

The recent CGM device is the Dexcom G7, which performs excellently compared to its predecessor. This guide mentions the top smartwatches and smartphones that work with Dexcom G7.

If you are looking for a Dexcom G7-compatible mobile phone for glucose monitoring, you don’t have to look for additional cash for test strips. You can reach us with any queries! 

Buying Guide:

Smartwatches can show your blood sugar levels but can’t measure them independently. They need to be connected to a CGM system to get blood glucose information and be as accurate as the CGM you use. 

Apart from the Apple Watch 6 and the newer, you will still be required to carry your phone as watches need connectivity to your mobile phone to display your blood glucose measurements. 

Not just blood glucose data, watches can help users with diabetes manage a healthy lifestyle. They can look at your intake calories, diet plan, heart rate, sleep patterns, and stress levels. 

These advantages are tremendous, but remember these devices are not accurate. Opting for a brand like Samsung or Apple is an excellent idea. These are expensive, but they are more precise and reasonably priced. 

Accuracy:

Accuracy is critical when working with a CGM, as this device measures your blood glucose. Accuracy also matters when measuring other metrics like pulse rate and blood oxygen. 

You need as accurate information as possible to get better insights into your health. This will let you know where you stand and where to improve. 

All of this helps maintain an impressive lifestyle, which is the key when living with diabetes. 

Design:

Smartwatches are designed with comfort, but you should ensure your choice is not bulky on your wrist. 

You’ll need to ensure your watch is not too big or small to meet your requirements. This depends on your build, but your lifestyle affects this, too. 

Watch face also matters a lot. There’s no need to buy a smartwatch if you keep squinting to read it. 

FAQs:

If you have connected your watch to a mobile, the Dexcom app for Android will work with Android wearables that support custom watch faces and meet app-compatible requirements. 

Does Dexcom G7 need wifi?

You can use a real-time CGM app without WiFi if connected to Bluetooth.

Yes, you can monitor your glucose from your wrist. The Android app supports Android wearables to show your glucose reading, and arrow trending.
