Google's Wear OS - formerly known as Android Wear - has had several big updates since it originally launched, all of which have pushed several new features, including iOS compatibility, making it increasingly more attractive, not just to Android users, but iPhone users too.
We have a separate best smartwatch feature with the best from all platforms including Wear OS, Tizen and Apple Watch OS, but this article is all about Wear OS. Here are the best Wear OS smartwatches currently out there.
Our top Wear OS smartwatch recommendation
This is the Wear OS watch that gives you oodles of style and all the smarts...
Tag Heuer Connected Modular 45
The Tag Heuer Connected Modular 45 launched in 2017 so it's over a year old now, but it's still a lovely smartwatch and the best looking you can buy (if you have the money). It is expensive, very expensive, but it's also dripping in quality and a smartwatch you'll actually want to wear.
The Connected Modular 45 reflects the Tag Heuer's Carrera watches with an added emphasis on personalisation. It not only offers watch face customisation, but physical customisation too and there is GPS and NFC to boost its digital skills, though it's not as fully-loaded as some rival devices.
This premium smartwatch feels like a premium smartwatch though and there's really nothing that matches the Tag Heuer Connected Modular 45's luxury position, while the modular approach remains unique.
Best of the rest Wear OS watches
The Tag Heuer Connected isn't for everyone though, especially given its price tag, but don't worry as there are plenty of other great Wear OS smartwatches that will probably fit your style or your budget better. Here are the ones that you should also consider:
Michael Kors Access Runway
The Michael Kors Access Runway is a fabulous smartwatch. It offers a solid build quality, a fashionable design, a lovely display and the Michael Kors customisable faces are a great addition. The battery life isn't the best out there and despite offering several fitness features, it's not really designed to work out in, but the overall experience is a great one.
You get a few extra features compared to the Access Sofie, which is a little further down this list, including built-in GPS and Google Pay compatibility, as well as a heart rate monitor. The Access Runway is also waterproof, as the Sofie is. It won't be for everyone, but for the Kors fan, it's everything you could want.
The TicWatch Pro is a very versatile smartwatch. It's an excellent Wear OS smartwatch but it's also an attractive smartwatch that can be worn to work and to work out, something not all smartwatches are able to offer.
The TicWatch Pro is comfortable too and while the chunky design won't be for everyone, it will be perfect for some. This smartwatch also offers a great battery life and it is much more affordable than some competitors.
Fossil Q Explorist Gen 3
Fossil offers numerous Wear OS smartwatches within its portfolio, including the Q Explorist Gen 3. This model offers a stylish design and build quality, 22mm interchangeable straps and it has programmable buttons that are very useful.
The battery life could be better and charging time takes longer than it should - there's no fast charging like the Kors Access Runway - but the Fossil Q Explorist Gen 3 has a lovely bright display and the Wear OS platform runs smoothly. This smartwatch is attractive, well made, waterproof and available in a choice of finishes and band styles.
Diesel On Full Guard
The Diesel On Full Guard smartwatch is a great smartwatch for Diesel fans. It offers a fashionable design and attractive styling but this is a very big smartwatch so you need to be a fan of the chunky look Diesel offers.
For those after a Wear OS smartwatch that is heavy on design but not necessarily full of features, the Diesel On Full Guard is a great choice. It has an excellent display, add on Diesel software and the the Wear OS platform runs smoothly.
Michael Kors Access Sofie
The Michael Kors Access Sofie is the second Michael Kors smartwatch, succeeding the Bradshaw and preceding the Access Runway, the latter of which has a little less bling and a few more features. The Sofie offers a luxurious and waterproof design, enough bling to make it stand out from the rest of the Wear OS crowd, while also offering a decent performance.
Unlike the Bradshaw, the Sofie comes with a fully round watch face and like all the Kors Access watches, customisable Michael Kors watch faces are on board, making this smartwatch feel that little bit more special than its competitors. The customisation options and the way "Looks" are organised are excellent too, especially for those who like to match their watch to their outfit. For the MK fans who love the signature, chunky and blingy watches from the company but want them connected, the Sofie is a great option.
The Casio WSD-F20 has been succeeded by the Casio WSD-F30 but the older model is still worth considering. It has a great rugged, durable design and it offers plenty of features. It's also fast, fluid and very responsive. There's a monochrome secondary screen that is very useful, while the sensors on board the WSD-F20 deliver accurate readings.
The Casio WSD-F20 isn't the best Wear OS smartwatch for sports tracking and it's colour screen isn't amazing for all outdoor activity but it is still one of the best performing Wear OS watches we've used. If you're not a runner, we can comfortably say this Casio is the best Wear OS watch designed for outdoor sports. The flip side of that is that Wear OS isn't necessarily the best platform designed for outdoor sports.
Huawei Watch 2 Sport
Huawei recently introduced a new smartwatch in the Watch GT, but the 2017 Watch 2 is still worth considering, especially if you can get it at a good price. It offers wearability and solid design, whilst also offering a 4G option, even if the battery life on 4G isn't amazing.
The battery life on Wi-Fi is a two-day affair though, which is more than many on this list. The Watch 2 doesn't have a rotational dial to make the most use of the Wear OS platform, and the strap isn't as premium as some other Wear OS watches, but on the whole, the Huawei Watch 2 Sport does a good job as a smartwatch.
