Great Watch 3 with GPS + Cellular, although I did not use the celluar. The space black stainless steel and the sapphire glass make it standout from the standard aluminum case version. watch is light compare to traditional stainless steel luxury watch. Good for workout and monitor daily activities.

I originally bought this product because my car doesn't have BlueTooth. The watch allows me to hit the green dot and take the call simply be holding the watch to my mouth. However, I do have one complaint; namely, the watch has so many features and accessing them is a matter of hit-or-miss.

since I bought this watch 3 weeks ago, I'm glad I got the one I did...the sapphire glass that comes with the more expensive stainless steel is worth the extra money in my opinion..it is very scratch resistant...check out consumer reports testing on this watch..

Bought this for my daughter for Christmas which was only 3 months ago. First off the second band that comes with it is junk and it was broke. Now the watch is starting to have problems with the roller on the side, it keeps getting stuck and the buttons aren't wanting to work anymore.

Love the watch. Got it as an anniversary gift for my Dad and he loves it. Amazon ran a pricing special on it and MicroCenter matched the price! You can't beat their customer service. Definitely recommend!

I love my watch! Just a random treat to me! Haha! My fiancé likes it as well, although he's a huge Samsung fan. Thank you so much! Exquisite customer service from the team!

When the Apple Watch Series 3 launched it didn't feel ready, but now it's a very different story. The big stand out feature is the 4G connectivity but the competitive price is also a consideration now that Series 4 has emerged. The Apple Watch is still the best smartwatch on the market.

Still a great smartwatch; Ability to leave your iPhone at home; Ease of making calls; Improved fitness features

No international roaming; Series 4's bigger screen sizes make it more compelling

Apple Watch is now in its third iteration, and while it may appear that not much has changed on the surface, there have been some developments under the hood. The big draw for the Series 3 is the option of LTE connectivity.

Snappier performance; Improved exercise tracking; Super-bright and clear display; Decent battery life (when not reliant on LTE; watchOS 4 improvements; Apple Pay is still super useful

LTE has a big impact on battery life; Needs more dedicated watch apps to make use of LTE; Need to wait for Apple Music streaming; Siri doesn't always work; No LTE roaming

Update: The Apple Watch Series 4 has been released and it's a belter, bringing a new design and more advanced health and fitness features. Read our Apple Watch Series 4 review to see which smartwatch is for you.

Leaves rivals floundering; Cellular a worthy addition; Plenty of design options; Great for general fitness

We want even more battery life; Restricted network choice

This killer app of the new Watch is the cellular service, so don't scrimp on that £70 and go for that version. The Watch itself is ready for this function it seems, but perhaps that's not the case for the telecoms providers – or provider.

Cellular service; S3 dual-core processor; comparable battery performance

Cellular setup; signal strength indoors; no playing nice with third-party services
