Reviews of The Best Thinnest Smartwatches

This section provides you with a detailed overview of the best and thinnest smartwatches, thereby helping you to pick the best option for yourself.

1. Apple Watch Series 6 – Best for Health Tracking Features


When it comes to the best smartwatch for thin wrists, Apple Watch Series 6 is a perfect option with a thickness of 10.4 mm and a unisex design.

This model proves to be the best thin smartwatch for health tracking features. It adds a blood oxygen saturation sensor to this high-end wristwatch from Apple. When turned on, this function helps calculate your SpO2 level and records this indicator periodically in the background while you’re inactive.

Given the worldwide COVID-19 epidemic, incorporating this technology into a consumer wearable is a crucial action.

It reveals how well your respiratory and circulatory systems are providing oxygenated blood throughout your body. After that, it gives you personalized medical suggestions.


The Series 6 is available in two case sizes: 40mm or 44mm, as well as three case materials: brushed titanium, stainless steel, or recyclable aluminum. This year, Apple Watch is also offering a few jewel-toned hues for you to select from.

Whether you like it or not, this model features Apple Watch’s signature squarish shape with rounded corners. The 40mm variant has dimensions of 1.56 x 1.35 x 0.42 inches (H x W x D), whereas the 44mm model has dimensions of 1.73 x 1.48 x 0.42 inches. Besides, it is 0.3mm thinner than its predecessors.

A speedier CPU, an always-on-display altimeter that shows your real-time elevation, and a boost in screen brightness while your wrist is down are among Apple Watch’s other upgrades. However, there is no improvement in the battery life compared to the former smartwatch model.

This thin smartwatch incorporates watchOS 7, the latest operating system version of Apple’s smartwatches. Specifically, it includes several smart features, including a sleep tracker and a 20-second countdown tracker for handwashing detection, cycling directions, and workout types.

Since Apple Watch Series 6 is slightly expensive, you can check out Apple Watch SE if you want a cheaper option.

  • SpO2 (blood oxygen saturation) measurements
  • Real-time elevation tracking with an always-on altimeter
  • Wrist-down screen brightness
  • Handwashing countdown timer
  • Fast processor
  • Attractive waterproof design
  • Slightly expensive
  • Improvable battery life

2. TicWatch Pro 3 – Best Waterproof Smartwatch


TicWatch Pro 3, with a thickness of 12.2 mm, is the first Google’s Wear OS smartwatch to employ a speedier processor, which breathes fresh life into the stagnating smartwatch line for men with thin to average-sized wrists.

This TicWatch model is the best waterproof version since it complies with the IP68 standards of the International Electrotechnical Commission (IEC). If you look for a masculine yet slim smartwatch that you can bring along while joining water activities in a swimming pool, TicWatch Pro 3 is an excellent choice.

TicWatch Pro 3 has a big 1.4-inch display screen with two screens stacked on top of each other. The above layer is a common LCD screen that displays the date, time, battery level, and steps without phone notifications.

Additionally, a clear and brilliant AMOLED screen sits under the LCD and illuminates when you’re actively engaging with the watch, such as browsing smartphone notifications or using apps.


This minimalist design from TicWatch is a brilliant way to improve battery life, but it might be inconvenient because you cannot check notifications at a glance. Moreover, switching between the two screens is startling at first because they don’t look anything alike.

Hence, you can always leave the primary screen on display like a conventional wristwatch if you prefer taking glances at your notifications. Particularly, this slim smartwatch goes with both Android and iOS devices.

  • Excellent battery life
  • Stunning dual-layer display
  • Useful TicHealth features
  • Optical heart rate monitor
  • Big screen for easy reading
  • Inconvenient smartphone notification display
  • Weak vibrations

3. SAMSUNG Galaxy Watch Active 2 – Best Smartwatch for Android


The Active 2 is available in two sizes: 40 mm and 44 mm (10.9 mm thick). Without the band, the 44 mm version weighs just 0.07 pounds, perfectly suitable for female users with thin wrists.

This thin smartwatch boasts a big, bright, and clear OLED screen that’s easy to see outside, as well as a great range of analog and digital watch faces and a big store of third-party options. Manufactured by SAMSUNG, the smartwatch is most compatible with Android devices coming from the same company.

The narrow bezel surrounding the screen’s edge has a secret trick. It functions as a touch-sensitive rotary controller, akin to previous Samsung smartwatches’ spinning bezels.

The Active 2 is waterproof to 50-meter depth, with a unique water mode that prevents inadvertent activation and removes water from the speakers when you exit. The watch is equipped with a superior silicone band and is compatible with normal 20 mm bands.


Regarding battery life, Galaxy Watch Active 2 can last up to 2 days even though you leave the screen on all day long. This smartwatch also comes with a fast-charging feature, so you can power it up in less than 2 hours using a magnetic puck on its back.

You can also use Powershare and wireless chargers to charge your watch from another Samsung smartphone’s back.

However, the sleep tracking feature of Galaxy Active 2 is not accurate as it usually miscounts the sleeping hours. Moreover, there are not many apps you can download with this version. Even so, the Active 2 is still the best thinnest smartwatch for ladies and worths your investment. Because it comes from one of the world’s leading brands, so the after-sales support will definitely be very good for a long time.

  • Automatically users’ workout pattern tracker
  • Exquisite classic design
  • Spotify offline storage
  • Durable battery
  • Heart rate monitor
  • 50-meter depth waterproof
  • Limited range of apps
  • Inaccurate sleep-tracking feature

4. Michael Kors Access Gen 5 Lexington Smartwatch – Best for Formal Occasions


With a thickness of 8 mm and a unisex design, Michael Kors is the thinnest smartwatch on this list. If you have a skinny wrist, this watch is perfect for you.

Because of the sophisticated design, it is the best option for formal occasions, such as meetings, business parties, competitions, etc. Otherwise, wearing this watch on a normal day might make you a little bit out of place.

In other words, the sleek design language of this smartwatch will not appeal to everyone because it requires an acquired taste. Those who like Rolex will definitely love this watch.

In terms of design, Gen 5 Lexington is made of robust stainless steel with the exception of the heart rate sensor-filled plastic bottom. It feels fantastic in hand, weighty, and comforting. At the top, there is a colored bezel, as well as the two-tone band, giving it a touch of class.


Michael Kors uses the Wear OS operating system by Google, allowing you to create countdowns, customize exercise modes, and save watch faces. This smartwatch has the same collection of applications as any other new Wear OS device.

Gen 5 Lexington comes with Google Fit, and this app has an automatic tracker, monitoring your workout patterns. However, it’s not a typical lifestyle smartwatch that you wear when exercising because it doesn’t make you feel comfortable, not to mention that the design is quite luxurious.

Regarding battery life, the 310mAh battery can last up to 36 hours of use, which is a decent number if you only use the applications once in a while. But if you use the built-in music player, GPS, or do anything else that requires extra power, you will need to charge it daily.

In short, if you need a luxurious yet slim smartwatch for parties or formal workplaces, the Michael Kors Gen 5 should definitely be on the top of your must-buy list.

  • Classy design
  • Built-in Google Fit app
  • Excellent default watch faces
  • Pre-installed latest software version
  • Supports phone calls
  • Water-resistant
  • Not suitable for daily use
  • Short battery life

5. Garmin Vivoactive 4 – Best for Outdoor Sports


Garmin Vivoactive 4 is a thin sporty smartwatch for both men and women with skinny wrists. Compared to the previous version, Garmin Vivoactive 3, there have been some design changes to fit both iOS and Android devices.

First of all, Garmin’s newest smartwatch is available in two sizes: a 40 mm version and a bigger 45 mm version, and both of them are 12.7 mm thick. As a result, this smartwatch from Garmin appeals to a larger range of consumers.

However, if you have a skinny wrist that can’t fit the standard version, Garmin Vivoactive 4S is a brilliant alternative for you.

When it comes to monitoring outdoor biking and running patterns, Vivo Active 4 is an ideal choice. This slim smartwatch takes less than 30 seconds for the watch to identify your GPS signal before displaying a map of your journey on the Garmin Connect application.


Garmin has always placed a higher value on battery life than other smartwatch manufacturers, and the Vivoactive 4 is no exception. This thin Garmin smartwatch can last approximately 7 days in the standard mode and 4 days if you listen to music and use GPS.

Nevertheless, this watch requires you to go through a complicated process to install a new app. Besides, the existing apps usually encounter synchronization issues, which might make you frustrated when your workout data is not updated timely.

  • Supports physical activity tracking
  • Heart rate monitor
  • Two-button navigation
  • Built-in Spotify music storage
  • Impressive battery life
  • Occasional synchronization difficulties
  • Complex app installation

6. Fossil Gen 5 Carlyle – Best Google Wear OS Smartwatch


The Gen 5 is a stylish thin smartwatch for men, with various bands, finishes, and colors to choose from. With a thickness of 12 mm and a width of 44 mm, the watch isn’t small, but the design makes it look incredibly thin to put on male wrists.

Thanks to automatic brightness control, the 1.28-inch AMOLED digital display screen is sharp, bright, and clear enough to view under the sun. By default, it is turned on all the time, so you can easily look at the smartphone notifications.

Fossil offers a plethora of highly customizable watch faces, most of which are pretty attractive, and you can look for more of them on the built-in Play Store. On one side of Fossil Gen 5, you can find a rotating crown, two buttons for launching apps, and a built-in speaker hole.

This thin smartwatch manages to put Google Wear OS’s concerns of low battery life and poor performance behind it. With a Snapdragon Wear 3100 processor and a RAM of 1GB, there is no apparent lag or decrease in speed in regular use.


The manufacturer has also improved the battery life. If you go with the “Daily” mode, your item can last up to a day since it activates all the smartwatch features.

In contrast, the “Extended” battery option can last above two days on a single charge. This option disconnects some power-consuming functions, such as the always-on display mode.

With Wear OS by Google, Gen 5 excels at managing notifications. Notifications appear at the bottom of the screen and can be ignored, enlarged to view the content of WhatsApp messages or emails.

Besides, you can also use the same choices as those provided in your phone’s notification shade, including archiving in Gmail.

A major disadvantage of Fossil Gen 5 is that it doesn’t support iMessage, so if you’re using an iPhone, checking messages on this device is impossible. Moreover, the battery life is quite disappointing as you need to recharge it daily.

Even so, if minimalism, masculinity, and personality are what you’re looking for from a lightweight and slim smartwatch, the Fossil Gen 5 Carlyle is definitely a great choice.

  • Compatible with both iOS and Android
  • 30-meter depth water resistant
  • Support third-party apps
  • Excellent music and notification controls
  • Enhanced battery management
  • Optical heart rate monitor
  • Doesn’t support iMessage on iOS
  • Short battery life

7. Fitbit Sense Advanced Smartwatch – Best for Lightweight Design


Fitbit Sense might be one of the slimmest smartwatches on the market for women with skinny wrists, measuring 40.5 mm wide and 12.35 mm thick.

Even though it is a bit thicker than the smartwatches reviewed above, the super slim design makes it the most lightweight model that you can put on your wrist.

The 1.58-inch OLED display screen is brilliant and is encased in a stainless steel bezel that houses the heart rate sensor’s electrical connections.

If you leave the screen on all day and turn on all features, the battery can work for about six days straight. For that reason, this watch’s battery life can easily beat other competitors.


Fitbit Sense uses the Fitbit OS operating system, which is quite friendly to users. Specifically, you can easily swipe down from the top to access smartphone alerts. If you swipe up, you can access other widgets such as weather and activity tracking data.

This thin smartwatch comes with quite a lot of useful fitness features. Fitbit can measure your active time. After that, the optical heart rate monitoring feature will track your heart every five seconds. Then, it gives you warnings of low and high heart rates.

However, repair experts on iFixit gave this smartwatch a not-good rating for repairability. The manufacturer doesn’t provide any repair services if you run out of warranty, such as battery replacements or display damages.

  • Lightweight
  • Exceptional battery life
  • Extensive health activity tracking
  • Ultra-slim design
  • Supports voice assistance
  • Useful heart rate monitor
  • Doesn’t support out-of-warranty repair
  • GPS accuracy issues

8. Amazfit GTR – Best for Battery Life


Amazfit GTR features a stainless steel case and a round dial with a diameter of 42 mm and 47.2 mm. With a thickness of between 9.2 and 10.75 mm, Amazfit is a super-thin lifestyle smartwatch for both men and women with skinny wrists.

Despite the steel construction, the company was able to keep the watch’s weight below 0.11 pounds. The watch is comfortable to wear for a long time, and the band material does not cause skin irritation or sweating.

This thin smartwatch includes a 1.39-inch AMOLED screen with a pixel density of 326 pixels per inch. A Corning Gorilla Glass 3 layer helps protect the touchscreen from scratches, and it has an effective anti-fingerprint coating.

Huami claims that Amazfit has a revolutionary battery life of 24 days, which easily beats all of the competitors on the market. If you turn off health tracking features and Bluetooth connection, it can even last up to 3 days.


Therefore, if you are looking for a slim smartwatch with an advanced heart rate monitor and an enormous battery capacity, this model is a choice.

Amazfit GTR also enables goal setting, progress monitoring, and notification management. The watch’s user interface is straightforward. You can swipe down to access and browse through settings and swipe up to keep track of activities, such as swimming and jogging.

A minus point for Amazfit is that it allows some third-party apps to integrate with its system. The touch screen is also quite lagging sometimes, making it hard for you to make calls or send messages.

  • Elegant lightweight design
  • Unbeatable battery life
  • 50-meter depth water resistant
  • 12 workout modes to follow
  • Stunning notification management
  • Lack of app integrations
  • Lagging touch screen

Things to Consider When Buying a Thin Smartwatch

Here are some essential things that you should consider to find the best and slimmest smartwatch for your wish.

1. Your Needs

The finest smartwatches range in price from $200 to $400. These more costly gadgets include sophisticated communications, a built-in music player, and fitness functions compared to cheaper smartwatches from $100 to $200.

More high-end choices will frequently have modern features such as NFC, music storage, and built-in GPS, which you rarely see on budget devices. Therefore, you need to clearly define your needs before making any decision.

For instance, if you only do basic workout exercises that do not need detailed and rigid tracking, a thin lifestyle smartwatch with basic trackers is more than enough. If you want more specialized workout patterns or music storage, more expensive items should be your choice.


2. Operating System

An important thing to look into is the smartwatch’s operating system (OS) you’re considering. Not all smartwatches are compatible with every smartphone. For example, Apple Watch can only go with an iPhone.

The majority of smartwatches work with both Android and iOS devices. LG Electronics uses Android Wear 2.0, a system that works with the latest iOS and Android phones.

Wear OS by Google is the best operating system for Android devices. However, some of its functionalities may not work properly on iPhones. The Fossil Gen 5 is, on the other hand, designed to work with both iOS 9.3+ and Android OS 4.4.

3. Design and Variations

It is advisable to find a lifestyle smartwatch that allows you to quickly swap out the bands. In this way, you will find it easy to change the straps when it wears out or when you want to try a different style to match your outfit.

In addition to the common silicone strap, leather straps are also an elegant alternative.

Besides, it’s a great idea to choose an item that works with common 16mm, 20mm, and 22mm bands. As a result, whether you have a skinny wrist or a larger wrist, you can still find a perfect band for your watch.


4. Water Resistance

If you enjoy outdoor activities such as kayaking, running, or hiking, you should seek a water-resistant wristwatch. A watch that can tolerate a 50-meter water depth would be an excellent choice, but you still need to minimize your exposure to water to keep your watch in perfect condition.

5. Glass Strength

It is annoying when you find some scratches on your smartwatches after a small accident.

A glass that has been reinforced can withstand regular wear and tear. Instead of acrylic glass, you should opt for sapphire crystal or mineral glass because they are more tolerant materials.

For instance, the sapphire crystal of the Apple Watch Series 6 can withstand scratches from sandpaper, knives, and keys. This material of Apple Watch ranks just below diamond in terms of mineral hardness.

6. Battery Life

Although battery life is still one of the most common complaints regarding smartwatches, progress has been made recently. Google’s Wear OS devices and Apple Watches may last up to two days. Extended battery modes are available on watches powered by the Snapdragon Wear 3100 chipset.

Specifically, this chip allows you to go a maximum of 5 days without charging, provided you’re prepared to turn off most modern features. As mentioned above, the battery life of Amazfit GTR can last up to 24 days, which no other item can beat until now.

A few smartwatches now have quick charging capabilities as well. Apple claims that the Apple Watch Series 6 can fully charge within 1 hour and a half. Hence, if you need a watch that charges up quickly so you can continue wearing it, Apple Watch Series 6 is a good choice.


The article has provided you with a thorough look at the best thinnest smartwatches on the market. The above lightweight designs fit perfectly with thin wrists, not to mention that the features make them more convenient for daily use.

There are many factors to consider when buying a smartwatch, especially thinner ones. If you usually work out in an outdoor setting, a lightweight and thin fitness smartwatch with basic health tracking features would be an ideal choice, such as Apple Watch Series 6, Garmin Vivoactive 4. On the contrary, if you need a luxury analog watch, the thin smartwatch less than 9mm thick from Michael Kors – Gen 5 is a suitable choice.
