Another ingenious thing of beauty but will you want one? Apple unveil the Watch that will you let you 'check into hotels, order an Uber and clock your heart rate - with 18 HOURS of battery life'

Apple has finally revealed its Watch in minute detail and announced how long it will last on a single charge. 

Since its unveiling in September the Watch has been shrouded in mystery, with Apple's boss Tim Cook teasing features at every available opportunity.   

But now everything - including its 'all-day' battery life has been announced - although the CEO added that with typical use this is more likely to be 18 hours. What 'typical' use entails remains unknown.

Prices for the Sport model start at $349 in the US and £299 in the UK, while the stainless steel Watch starts at $549 (£479) and the Edition costs from a staggering $10,000 (£8,000). The most expensive model in the US will cost $17,000 (£11,200).

It comes in three models: the Apple Watch, Apple Watch Sport and Apple Watch Edition, and all models are sold in either 1.4-inch (38mm) or 1.7-inch (42mm) versions.

The Apple Watch boasts a number of applications, including GPS navigation, a heart monitor, hands-free messaging and a personal trainer. It also features the Apple Pay system which allows users to make payments at tills by passing the watch, preloaded with account details, over a scanner

Apple CEO Tim Cook, right, and Christy Turlington Burns, founder of Every Mother Counts, discuss the new Apple Watch earlier today in San Francisco, California. 'It even reminds you if you've been sitting too long and it can set you a new movement target each week', explained Cook

                                       

Apple's Watch is available in three models: the Watch, Watch Sport and Watch Edition (shown) and all models will be sold in 1.4-inch (38mm) or 1.7-inch (42mm) versions. Apple Watch is made of stainless steel, Sport is made of Aluminum and the premium Edition comes in 18-Karat Rose Gold and Yellow Gold

Interchangeable straps include fluoroelastomer (rubber), leather, and stainless steel and this will mean both left-handed and right-handed people can use the Watch by fitting the strap so the digital crown is on the opposite side. 

Connecting to the iPhone, the Apple Watch is designed as a wrist device for messaging and calls and for a variety of health tracking applications.

'With the built in speaker and microphone you can receive calls on your watch. I have been wanting to do this since I was five years old,' Cook said.

The watch is also integrated with Apple Pay's mobile wallet, and can be used to view pictures and monitor news, and also connect to social media. 

It can use other apps ranging from Uber ride-sharing to music to home automation.

'Now it's on your wrist, not in your pocket or your pocketbook,' Cook said.

'I think you're going to be surprised at what developers can do when you unleash that community.'

Apple demonstrated using the watch to listen to music, with lyrics displayed on the watch face. 

The company also demonstrated an app to open a garage door from afar to let in a family member who is locked out.
