Best 15 Thinnest Smartwatches For Slim Wrist 2021

People with thick wrists prefer large bulky watches as they suit them perfectly fine. But what about slender/slim wrist? to put it another way, are there any smartwatch people looking for a sleek, comfortable timepiece?

Fortunately, there are plenty of them. We have rounded up some of the best thinnest smartwatches. A unique characteristic of these watches is a slim, slick, and comfortable design. Surely a thin profile does dictate engineers to make a few trade-offs here and there. But we assure you, the watches in this list have up-to-date features.

Other than the modern features like a voice assistant and NFC, these watches are elegant in design and stylish in looks. They are highly visually appealing. And above all, these watches are comfortable to wear all day round without any hassle. 

We have compiled a list of the 10  best thinnest smartwatches for you. And we promise you, we will keep on updating this list as new watches hit the market.

Other than the thin profile of the smartwatch, we have also considered other features while rounding them up for this review. We have discussed them briefly in the buying guide below. Go through it if you are not in a hurry. 

Thinnest Smartwatches For Slim Wrist: Buying Guide

While looking for a slim smartwatch, you will have to consider two features before you get into details. First, the weight of the watch, and second the thickness of the watch. Also, you will have to make sure that the watch has a low screen to casing size ratio, so it should have a small bezel. 

The cut-off limit for thickness is 10-11mm, and the overall weight should be no greater than 80 g. 

Next, you will have to make sure that it has all the necessary features. The word ‘necessary’ here is subjective. Some people are looking for health or fitness features like heart rate, sleep, or step tracking. Others need more smart features like contactless payment, voice assistant, and calling and texting feature on the watch. Prioritize what kind of features do you need. 

While designing a slim smartwatch, most manufacturing companies make a trade-off in the form of durability and strength. Rugged smartwatches are not the slimmest watches around, and vice versa. 

Nevertheless, the smartwatch must be water-resistant for up to 5m. And it should be completely dustproof. In technical terms, it should be ATM 5 or IP68 rated.

Apart from that, the companies make another trade-off in battery size. A small battery size means a small battery life, and some people just hate to charge their gadgets overnight. To balance it out, make sure that the smartwatch supports fast charging, and if not that have several battery modes to extend the battery life. 

Manufacturers also make a trade-off in the display, and instead of AMOLED screen type, they use the cheaper LCD screen in thin watches. We would personally recommend the former (AMOLED display) despite the fact that it drains battery life like hell. What is the point of buying a slim and stylish watch with a dull and lackluster display?

A TizenOS based military standard watch but a quite thinner and sleeker design:

DISPLAY:

Samsung takes its displays quite seriously. Active 2 is equipped with a 1.4 inches, 360×360 pixels AMOLED display. The display quality is flawless, with colors popping like always and crystal clear clarity. 

BATTERY:

The battery life of Active 2 lives up to Samsung’s claims of two days. This can be tweaked up by the use of the battery saver mode. The battery drains quite fast with the use of more activities though.


One of the most ambitious designs out in the market:

Fitbit Sense

$329.95
$248.95

13 new from $248.95
Free shipping
as of April 19, 2021 5:45 am

Fitbit makes quite some claims about the battery timing of this watch, rightfully though. The watch can easily keep going for 6 days with minimal to no GPS use. Continuous GPS use causes to run only for 12 hours at the max. 


Tons of goodness in a sleek package that won’t be a hit on your wallet:

Aamazfit GTS

$119.99
$104.99
 in stock
3 new from $104.99
1 used from $104.99
Free shipping
as of April 19, 2021 5:45 am

 COMFORT AND DESIGN:

The watch is top-notch design-wise. One might confuse it with the Apple series 5 except that this weighs unbelievably light at 22 grams. The build is solid and the watch doesn’t feel cheap. The straps are comfortable to wear and fit even the smallest of the wrists. 

SIZE:

The watch is just small. With the dimensions of 43.25 x 36.25 mm the watch is square-shaped. And it is very, very thin. Only about 9.4 mm. Seems like the watch is a part of your body.               

DISPLAY:

Its small size has caused absolutely no hindrance in the display aspect of the watch. 1.65 inches AMOLED delivers above-average performance. With a resolution of 442 x 348 pixels, clarity and quality is not a problem. Colors are popping too. 

BATTERY:

The watch has beastly battery life. While the company’s claim of a 14-day battery maybe a tad overzealous, the watch does last for about 10 days without any problem. This number itself is very competitive.
