The Apple Watch Series 4 is the fifth generation of the company's smartwatch. It succeeds but doesn't replace the Apple Watch Series 3, while the Series 2, Series 1 and original Apple Watch have all been discontinued through Apple. Luckily, all the straps remain compatible across all the generations.

With two main ranges, GPS and GPS and Cellular models in both ranges, two different sizes in each range, plus all the straps that can be mixed and matched, as well as the extra Nike+ and Hermes models, choosing the right Apple Watch for you is trickier than it first seems.

This feature explains what models are available, how much they cost and what the differences are between them all in order to find the right one for you and your budget.

Apple Watch Series 3


View the Apple Watch Series 3 model from £279 on Apple.co.uk


  • Sizes: 38mm, 42mm
  • Models: GPS only and GPS and Cellular
  • Material: Aluminium body
  • Colours: Silver, Space Grey aluminium casings
  • Strap included: Sport Band or Nike Sport Band, colours dependant on casing
  • Price: £279 to £309

The Apple Watch Series 3 offers a S3 processor, coupled with built-in GPS, a waterproof body and a barometric altimeter, all of which were added over the older Series 1 model. The S3 processor is combined with a W2 wireless chip that enables Siri to work on the Watch itself rather than passing over to your iPhone. 

There are four standard models available and two Nike+ models available, all of which have an aluminium casing. The stainless steel models are now only reserved for the Series 4 models - more on those below.

Your options for the Series 3 model are therefore a Silver aluminium case with a White Sport Band, a Space Grey aluminium case with a Black Sport Band, or a Space Grey aluminium case with the Anthracite/Black Nike Sport Band. Each option is available in GPS only or GPS and Cellular, with the latter meaning it will work independently of your iPhone.

You can of course buy an additional Sport Band or different strap separately however - we'll go into more detail about those further down. If you want a different strap, you have to pay for it on top of the price of the standard model and the strap it comes with.

Apple Watch Series 4


 View the Apple Watch Series 4 from £399 on Apple.co.uk


  • Sizes: 40mm, 44mm

  • Colours: Silver, Space Grey, Gold aluminium casings, Stainless Steel or Space Black Stainless Steel casings
  • Strap included: Sport Band, Sport Loop, Nike Sport Band, Nike Sport Loop, Milanese Loop, Hermes Leather Strap (all colours for all straps dependant on casing)
  • Price: £399 to £1499

The Apple Watch Series 4 brings many of the Series 3 features including waterproofing and built-in GPS but it introduces a new S4 processor with W3 wireless chip, an electrical heart sensor on the Digital Crown and a bigger display within a similar footprint as the Series 3 resulting in a bolder design. It also comes in new size options of 40mm and 44mm. The aluminium models start at £399 with a Sports Band, the stainless steel models start at £699 with a Sport Band, £799 with the Milanese Loop strap or £1249 with a Hermès strap.

There are 18 standard models available, ignoring the specialist ranges like Nike+ and Hermès for now - we'll go into those further down. These 18 models are made up of six GPS only models, all of which have aluminium casings, and 12 GPS and Cellular models that are available in aluminium and stainless steel options.

Your options for the Series 4 are therefore a Silver aluminium case with a White Sport Band or a Seashell Sport Loop strap, a Gold aluminium case with a Pink Sand Sport Band or Pink Sand Sport Loop strap and a Space Grey aluminium case with a Black Sport Band or Black Sport Loop strap. All of these six options are available in GPS or GPS and Cellular.

Moving onto the stainless steel options, which as we mentioned are GPS and Cellular only, there is a Silver Stainless Steel case with a White Sport Band or a Silver Milanese Loop Strap, a Gold Stainless Steel case with a Stone Sport Band or a Gold Milanese Loop strap and a Space Black Stainless Steel Case with a Black Sport Band or a Space Black Milanese Loop strap.

Like the Series 3, you can buy an additional Sport Band or different strap separately for the Series 4 models.

Apple Watch Nike+


View the Apple Watch Nike+ from £279 (Series 3) or £399 (Series 4) on Apple.co.uk


  • Sizes: 38mm, 40mm, 42mm, 44mm
  • Models: GPS only and GPS and Cellular
  • Material: Aluminium body only
  • Colours: Silver or Space Grey aluminium casings
  • Strap included: Nike Sport Band or Nike Sport Loop (Series 4 only), colours dependant on casing
  • Price: £279 to £529

The Apple Watch Nike+ is one of the special edition ranges of the Apple Watch, created in association with Nike, as you probably guessed from its name. Previously, the Nike+ model has been reserved for only the newest devices, which would have been the Series 4 in this case, but this time Apple has retained the Nike+ model from Series 3 too.

The hardware is respective of the Series, so the Series 3 Nike+ models have the same specifications as the standard Series 3, while Series 4 Nike+ models have the same specifications as the Apple Watch Series 4, meaning they have the newer processor, improved accelerometer, new display design and the electric heart sensor in the Digital Crown. The difference between the Nike+ models and the standard Apple Watch models is the special Nike Sport Band or Nike Sport Loop strap rather than the plain Sport Band or plain Sport Loop strap.

Like the aluminium Apple Watch Series 3, the Apple Watch Series 3 Nike+ starts at £279 for the 38mm model, moving up to from £309 for the 42mm, with prices increasing by £100 respectively if you then select GPS and Cellular over just GPS. The Apple Watch Series 4 Nike+ models start at £399 for the 40mm size, like the standard Series 4 model, increasing to £429 for the 44mm. Again, add another £100 on top of both for the GPS and Cellular models.

There are 10 Apple Watch Nike+ models available in total, two Series 3 models and eight Series 4 models. There are then two sizes in each, with 38mm and 42mm options in the Series 3 and 40mm and 42mm options in the Series 4.

The Apple Watch Nike+ model colour options are a Space Grey aluminium case with the Anthracite/Black Nike Sport Band (Series 3 and Series 4), a Silver aluminium casing with the Pure Platinum/White Nike Sport Band (Series 4 only), a Silver aluminium case with Summit With Nike Sport Loop strap (Series 4 only) and a Space Grey aluminium case with Black Nike Sort Loop strap (Series 4 only). All models come in GPS and GPS and Cellular options.

As with the Series 4 models, alternative straps can be bought separately for the Series 3 and Series 4 Nike+ models for an additional cost, including different Nike Sport Band colours.

The Apple Watch Hermès is another of the specialist ranges, this time created in collaboration with Paris fashion brand Hermès. The collaboration was first seen on the original 2015 Apple Watch but it is now only available on the Series 4 models.

There are 11 Apple Watch Hermès models to choose from, each of which has a special Hermès watch face, leather straps handmade by the fashion company's artisans in France and the Hermès logo on the underside of the watch body, as well as on the strap. Not all models are available in both 40mm and 44mm sizes though.

Five models of the eight are only available in the 40mm size option: Stainless Steel Case with Indigo/Craie/Orange Swift Leather Double Tour, Stainless Steel Case with Bordeaux/Rose Extrême/Rose Azalée Swift Leather Double Tour, Stainless Steel Case with Bordeaux/Rose Extrême/Rose Azalée Swift Leather Single Tour, Stainless Steel Case with Bleu Indigo Swift Leather Double Tour and Stainless Steel Case with Fauve Barenia Leather Double Tour.

Prices for the Apple Watch Hermès start at £1,249 with the most expensive hitting £1,499 so significantly pricier than the standard Series 4 models.

Apple Watch Straps

There are numerous straps available for the Apple Watch, each of which is compatible with all of the ranges.

As we mentioned above, you can buy any of the straps below separately to give you an alternative option to the strap included with the Apple Watch model you pick but you are still stuck with the standard strap that comes with that model. 

For those with a Series 1, 2 or 3 Apple Watch, you'll notice the sizes are now 40mm and 44mm instead of 38mm and 42mm. When choosing a strap, choose the 40mm size for the 38mm model and 44mm size for the 42mm models.

Best Apple Watch and strap combinations

Let's quickly do the maths: the cheapest Apple Watch Series 3 is £279 (40mm) and the cheapest strap that isn't a Sports Band is £49, a total of £328. That's £71 cheaper than the most affordable Apple Watch Series 4, which starts at £399 (40mm) and also has the Sports Band and aluminium case. You lose out on the bigger display, improved processor and electrical heart sensor though.

If you can live with the aluminium body rather than stainless steel, then the Series 3 or Series 4 GPS only model is the cheapest route and with the choice of three aluminium colours in the Series 4, it's an appealing route too.

For example, you could get the 40mm silver Apple Watch Series 4 and smarten it up with the Classic Buckle strap for a total of £548. You could also opt for the aluminium Series 4 and whack a Hermès Single Tour strap on it for a fashionable total of £739 for the 40mm option. Choose the Series 3 models instead and the prices would be £428 and £618 respectively.

Another good combination is the aluminium Space Grey Apple Watch Series 4 (44mm) with the Space Black Milanese Loop strap. The body costs £399 for the GPS only model or £529 for the GPS and Cellular model and the strap costs £149, for a total of £548 or £678, respectively. The Space Black stainless steel option (44mm) would cost a total of £849 with the Space Black Milanese Loop strap and even though you would get a Black Sport Band in that price too, you'd save at least £170 opting for aluminium over stainless steel.
