Which Apple Watch should I buy? The range of models, materials, colours and straps was baffling enough even before the new Apple Watch 2 was unveiled, which has made things even more complicated. Here, we help you choose between Apple Watch Series 1 and Apple Watch Series 2, and which models within those will be best for you. Also see: Black Friday Apple Watch Deals 2016.

The Apple Watch made a big splash when it launched in 2015, and was one of the hottest Christmas presents that year. It later saw a major software update with watchOS 2, followed by a second update in 2016 with watchOS 3. There have also been plenty of new straps, and some new colour options too. For those without an Apple Watch or those ready to buy a new one, the big new arrival came in September of 2016, which is when Apple released the new Apple Watch Series 2 range. It also updated the older model of Apple Watch with a new processor, now called Apple Watch Series 1.

We still don't know for sure whether the Apple Watch will be a long-term success by Apple's standards – the real test will be sales of the Apple Watch Series 2.

But which model of Apple Watch is right for you, your needs and your budget? Which edition, size, case material, colour and strap should you go for? Which is the best value-for-money choice? With over xx combinations available, the choice can be overwhelming.

In our Apple Watch buying guide, we explain all the options and help you decide a) which Apple Watch you want, b) which Apple Watch will suit you, c) which Apple Watch you can afford, and d) where to buy your Apple Watch from.

Apple Watch buying guide: Where can I buy an Apple Watch?

You can now pick up the Watch Series 1 and Watch Series 2 from an Apple Store (or order one online), where you can also buy the very expensive Apple Watch Edition. Prices range from £269 to figures well over £1,000. Note that Apple is no longer selling the Gold models of Apple Watch Edition, which were available for up to £13,000 when the original Apple Watch series was launched.

You can also buy the Apple Watch from third-party retailers, including John Lewis, Currys, and Very.

Apple Watch buying guide: New models

Apple now sells the Apple Watch Series 1, Apple Watch Series 2, Apple Watch Nike+, Apple Watch Hermes and Apple Watch Edition (the latter three are all part of Series 2, too).

With five different watches to choose from, or six if you include the original Apple Watch that is still on sale at some third-party retailers, it is really tricky to know where to start.

The Apple Watch Nike+, Apple Watch Hermès and the Apple Watch Edition all have the same internals and specifications as the Apple Watch Series 2, but have distinct aesthetic appearances. And you can choose between aluminium and stainless steels for the case of the Apple Watch Series 2.

The Apple Watch Nike+, which like is made with aluminium, is aimed at those who love running and are looking for a sport-orientated smartwatch. We see the Nike+ as an Apple Watch Sport replacement.

The Apple Watch Hermes and the Apple Watch Edition are both aesthetically different to the standard Series 2 watch, too. The Hermes is made with Stainless steel, with a unique strap and a Hermes stamp on the back, while the Apple Watch Edition is made with white ceramic, giving it a unique design. Both of these watches start at more than £1,000.

Best Apple Watch: Apple Watch Series 1 vs Apple Watch Series 2

And then there's the Apple Watch Series 1, which is a rebadged version of the original Apple Watch that has a new upgraded processor.

The Apple Watch Series 2 features built-in GPS, IP67 water and dust resistance, and a 50 percent brighter screen. These are the main differences between the Series 1 and Series 2, in addition to some new strap options at checkout (but those will also be compatible with the Series 1 and original watch).

Both the Series 1 and Series 2 come with a dual-core processor, which is the only differentiator between the new Apple Watch Series 1 and the original Apple Watch. It's important to note, though, that the Series 1 comes with a S1P dual-core (not to be confused with the single-core S1), while the Series 2 houses an S2 dual-code processor. From what we know, the only difference between the S1P and S2 chips is the S2's ability to hand a GPS signal. Both S1P and S2 chips feature a better GPU, which renders faster images on your watch.

Looking at the materials used, the stainless steel version of the Series 2 has the sturdier sapphire glass screen, while the Series 1 is protected with Ion-X glass. It should be noted that the aluminium models of the Series 2 are also made out of the same Series 1 glass-material.

Price wise, the Series 1 starts at £269, while the Series 2 starts at £369. Prices increase when you start changing straps and materials. There is only the Sport Band available for Series 1 models, but if you want a different strap you can purchase it separately, but that will of course cost you a few more pennies. See our dedicated article on Apple Watch straps.

Apple Watch buying guide: Should I upgrade from the original Apple Watch?

If you've already got an Apple Watch, it's worth considering whether it's really necessary to upgrade to Apple Watch Series 1 or Series 2.

The answer is yes if you are super-excited about the idea of built-in GPS, water resistance and a brighter screen, all of which are most useful for sporty types. If those things sound appealing but nothing special, it's then worth considering whether the speedier dual-core processor is really worth the extra investment.

The dual-core S1P and S2 processors are up to 50 percent faster than the single-core processor found in the original Apple Watch. This will make a difference when considering the speed at which apps are launched. The chips also feature a better GPU, making images look better and render faster. So it all depends on how sluggish you feel your current Apple Watch is. We think it's worth popping into an Apple Store if you can to test the speed of the Series 1 and Series 2 to see if the difference is noticeable enough to you personally.

If you haven't already done so, we'd recommend updating your Apple Watch to watchOS 3 before you consider upgrading too, as it brings a healthy boost to the user interface and the speed of the watch and its apps.

Apple Watc Series 2 - Design

Apple Watch buying guide: Should you buy the 38mm or 42mm size?

The Apple Watch comes in two sizes of case: 38mm or 42mm. The general interpretation is that these are designed to suit an average woman and an average man's hand/wrist dimensions respectively, but you needn't feel bound by that: there are no other changes to the design of the watch other than size - no explicitly masculine/feminine decorative elements etc. (Also, a bloke can wear a woman's watch if he wants to. Don't let anyone tell you different!)

The 38mm/42mm measurements represent the (approximate) height of the watch face, in millimetres. That's a bit weird, because when categorising sizes of smart devices we usually refer to the size of the screen, measured diagonally from corner to corner, in inches. (The iPhone 5s is a '4-inch smartphone', for instance.) But Apple seems to have decided to do things differently this time. We'll see if this sticks and becomes the de facto standard.

The full and exact dimensions of the two sizes of Apple Watch (height x width x depth) are:

'38mm model': 38.6mm x 33.3mm x 10.5mm
'42mm model': 42.5mm x 36.4mm x 10.5mm

Weight obviously varies according to the material. It should also be noted that the Series 2 has a depth of 11.4mm and not 10.5mm.

Apple Watch buying guide: Which size should you get?

The size of a wearable is a crucial, critical factor, and because of this, I would recommend that you postpone the buying decision until you can be sure which size is right for you. That might mean buying in store rather than ordering online; if you can get to an Apple Store or a reasonably well-appointed reseller then they will have watches in stock that you can try on before buying.

Finally, bear in mind that the available configurations of material/colour/strap are slightly different for the 38mm and 42mm sizes - so your choice in this category will slightly reduce your options in others. I strongly recommend that prioritise size above other considerations, however. Don't be like the shoe shopper who goes one size too big because they're 90 percent off - the pain isn't worth it!

Apple Watch buying guide: Which colour do you want?

The material used determines what colour you can find the Apple Watch. In aluminium you'll find it in white, space grey, gold or rose gold. In stainless steel and black stainless steel. The ceramic version naturally represents its white material and is only available in that colour.

The colour per material, doesn't affect the price, so pick whichever version you like best. You will however notice a difference in price between the 38- and 42mm versions.

Apple Watch buying guide: Pick a strap

Your choice of strap does affect the price - fairly drastically, in the case of the Apple Watch, Apple Watch Edition and Apple Watch Hermes.

The ten straps are:

Sport Band
Woven Nylon
Classic Buckle 
Modern Buckle
Leather Loop
Milanese Loop
Link Bracelet
Hermes Single Tour Strap
Hermes Double Tour Strap
Hermes Cuff Strap

Apple Watch buying guide: straps

Each of these is available in multiple colour options, which vary according to the model of Apple Watch you've selected.

(There are some nice third-party straps out there too. We've collected our favourite first- and third-party Apple Watch straps in a separate feature: Best Apple Watch straps.)

Apple Watch docks, stands and chargers

The Apple Watch comes with a small, basic charger, but you may wish to buy an additional dock that allows you to charge overnight while also displaying the time. For our picks, see our roundup of the best Apple Watch stands and charging docks.

Apple Watch buying guide: Which watch face should I get?

That's up to you, but it's a settings option, not a buying one. You don't need to specify a watch face when you buy. You can change the face whenever you like, so experiment and see which one you like best.

There are thirteen watch faces (which are further customisable, in terms of colours and so on):

Chronograph
Colour
Modular
Utility
Mickey Mouse
Simple
Motion
Solar
Astronomy
Timelapse
Photo
X-Large
