Orders for the watch are being taken solely online at this stage and demand is expected to outstrip supply.
While you can head to Apple stores and Selfridges in London to check out the watch range - which numbers a massive 38 different styles - in real life, you could miss out.
Indeed, at least one style - the top of the range £13,500 18 carat gold watch - has already sold out.
With Apple's dizzying array of choice - and perhaps more importantly, prices - the decision on which to go for is a tough one.
Here's our quick at-a-glance guide to all the options to make sure you don't miss out on getting your hands on the Apple Watch. Still wondering if it's worth getting one? Here's what the critics think.
There are three different main styles of the Apple Watch.
The Watch Sport
It comes in silver aluminium with a sports band style strap in a selection of five colours.
This stainless steel watch has a selection of strap colours and styles in leather and metal for a smarter look.
The Watch Edition
The luxury version of the watch comes in 18 carat gold and a number of strap colours and materials.
Most of the watches come in two sizes - 42mm or 38mm.
