Here are our top picks for the best smartwatches of 2021 in the UAE.

Smartwatches have gone from being a niche piece of technology with limited applications in the early 2010s to being an essential part of any discerning technophile's fashion arsenal. Smartwatches, particularly autonomous e-sim smartwatches, have become increasingly popular in recent years.

Without a phone, a smartwatch with an eSim can make and receive calls, as well as send and receive messages. This offers an independence from larger smartphones, which can be inconvenient at times, especially when you're exercising.

The best smartwatches do more than just notify you when you get a call or receive a text message on your wrist. They're a fitness tracker that can also serve as a phone in some cases, even if your smartphone isn't nearby.

The best smartwatch, on the other hand, can do these things better than others. Some have a large number of apps to download, and some have batteries that last only a day or two, while others can last nearly a week or more on a single charge.

Furthermore, there is style and design: the best smartwatches are made of premium materials such as glass, titanium, and ceramic, which will blend in with any outfit.
