Apple has unveiled its long-awaited smartwatch, set to go on sale early next year, as well as its new iPhone 6.
While it can tell the time accurately to within "50 milliseconds of the definitive global time standard", the Apple Watch also runs apps, delivers text messages and emails and will even track how fast you run.
The California tech giant also announced details of the new "dramatically-thin" iPhone 6 and the iPhone 6 Plus. So here's a quick Q&A to all you need to know about both products.
The Apple Watch
What does it do?
Of course, it tells the time – and you can personalise how it is displayed. There are two million different combinations available. But it can also serve as a phone – yes, you'll be able to make and receive calls, as well as texts and emails and listen to music.
The watch also serves as an ultra fancy pedometer, counting your steps, as well as the "frequency and quality" of them, and a Workout app will keep track of cardio sessions and show you real-time stats such as time, distance, calories and pace. Oh, and you can use your watch as a remote for your Apple TV!
How do you control it?
You need to have an iPhone 5 for the Apple Watch to work. The "Digital Crown", a dial at edge of the watch face casing, allows you to zoom, scroll, and select without covering the screen. The watch will give you "a gentle tap" when you receive an incoming message.
How many styles does it come in?
Three – the stainless steel case Apple Watch model, a silver or space grey aluminium case Apple Watch Sport model, and an 18-karat yellow or rose gold case Apple Watch Edition model. All have a variety of straps. And all come in two case sizes: 38mm and 42mm.
How much will it cost?
It will cost from £300 and upwards depending on the model.
When does it go on sale?
The iPhone 6 and 6 plus
How big are they?
The iPhone 6 has a 4.7-inch Retina HD display and the 6 Plus has a far bigger 5.5-inch Retina HD display. They're the thinnest ever iPhones at 6.9mm and 7.1mm thick respectively.
They'll be faster thanks to the new A8 processor (which should make it 25% faster than the iPhone 5s), the screens are bigger and sharper, the camera's been upgraded to 8 megapixels and will have a better autofocus than previous models. The battery life's been extended too and they come with a range of leather and silicon covers.
What will it cost?
The iPhone 6 will cost roughly the same as the iPhone 5S, but the 6 Plus should cost about £100 more. The 16GB 5s is currently on sale for £459 through the Apple store. Prices of iPhone 6 and 6 Plus covers are yet to be announced.
When does it go on sale?
Should I buy one?
Dominic Baliszewski, telecoms expert at broadbandchoices.co.uk, says: "Die-hard Apple fans will no doubt be ready and waiting to order their handset, but we would encourage customers to wait and see the impact this launch has on the price of the 5s handset.
"Given that the new iPhones only marginally improve on features the older handset already has, you may be better off opting for the 5s and enjoy fantastic specifications for a more palatable price."
