Best UK Smartwatch Deals for August 2021

Smartwatches are getting better every year. They can now last for more than a day on a single charge, track your workouts, take calls, play music and more.

Some dish out notifications and tell you when it’s going to rain, while others can function untethered from your phone completely.

What smartwatch should you buy?

There are two overarching types of smartwatch frameworks you'll likely encounter. One – in the vein of the Apple Watch – features a colour touchscreen and often supports apps, while the other combines an analogue watch with smart features. These are semi-smart or hybrid watches and typically use less battery since they're not required to power a full-face display. You can find in-depth buying advice on smartwatches in our round-up of the best smartwatches available right now.

The Apple Watch is still the dominant force in the smartwatch market but many smartwatches from the likes of Motorola and Fossil run Wear OS, while Samsung's run its own Tizen UI (at least for now).

Make sure you consider whether or not your phone is compatible with the smartwatch you’re after too; the Apple Watch only plays nice with iPhones and most Wear OS watches require your phone to be of a certain age and running a certain version (or later) of iOS/Android.

There are also designer smartwatches that often run Wear OS from brands like Diesel, Armani and Tag Heuer. They are often very expensive, so if you have your eye on one it's a good idea to look out for discounts.

Smartwatch Deals: Is pay monthly worth it?

Seeing as smartwatches work hand-in-hand with your smartphone, many phone retailers and network carriers let you split the cost of a cellular-capable smartwatch over your pay-monthly phone plan. Of course, these deals work to finance the device, so it’s worth weighing the long-term costs against the upfront costs.

Alternatively, while some plans let you share your phone's network and contract, there are still other plans which get you separate unlimited data allowances for your Apple Watch (and other select LTE-capable watches).

In the UK, EE and Vodafone are the two networks that carry the likes of the Apple Watch and Samsung's latest smartwatches on cellular. You can often get the device for £0 upfront. See

EE’s plans here


Similarly to buying a new phone on a monthly plan, however, you do end up paying more at the end of the contract, but if you prefer to pay in small increments instead of all at once, this may be a better option.

Where to find smartwatch deals

Amazon often has some of the biggest discounts on smartwatches and other tech but it's always worth shopping around if you don't see something you like in our selection here.

If you find that you’re missing out on Amazon’s Lightning deals, which run for just a few hours and offer limited stock, we'd recommend signing up for Amazon's 30-day free trial of Prime, which will get you access to deals 30 minutes before everyone else. Plus, you'll get free next-day delivery with the Prime trial, as well as access to Prime Instant Video and more.

Smartwatch accessories

Of course, the smartwatch itself is only part of the equation. You may also want to use a different strap from the one provided or freshen the look if you've been using the same strap for a while.

This might be especially relevant to Apple Watch users, with the plethora of band choices available (here's how to change your Apple Watch band). Though the Apple store may be an obvious place to find straps for your Apple Watch, you would be hard-pressed to find any bands for less than £49.

You can, however, find third-party alternatives on Amazon for less than £10/$10, though make sure you're buying it for the correct watch casing size. Gearbest is another place where you can find watch bands of various designs but at more affordable prices.
