Stunning new images show how Apple's timepiece might look in a range of colours

Watch could be available in C and S versions - just like the iPhone
Reports claim the first-generation Apple iWatch will be wirelessly charged
Set to monitor health and sleep
Apple also said to be developing 'healthbook' app to analyse data

An Apple fan has released stunning new images of what he believes apple's iWatch could look like.
The images reveal two models, a luxury iWatch S with a metal case and leather strap, and a plastic iWatch C.
The incredibly realistic images were mocked up by artist and Apple fan Martin Hajek, and even show how the timepiece would look in Apple''s retail stores.

Apple fan and artist Martin Hajek created these incredible lifelike mockups of an iWatch, whcih he believes could come in two version, with the top of the range being the iWatch S, which has a metal body and leather strap

The mockups are Hajek's second attempt at an iWatch, having worked with Mac User magazine for the first.
'Right after Apple launched the colorful iPhone 5C I figured it would be nice to have a look at adding color to my original iWatch concept,' he said.

'I added some color, simplified the design and basically turned it into an iPhone 5C for around your wrist.'
The latest rumours around the secret smartwatch claim Apple has hired a raft of medical and sleep experts to work on its iWatch project, it has been claimed.
It is believed the watch will be able to monitor both exercise and sleep, letting wearers track and analyse their every movement.
Although the firm has refused to confirm it is even working on a watch, experts believe it could be released this year.

9to5Mac reported that Roy J.E.M. Raymann -- whose background includes working on wearables, sensors and non-pharmacological methods of improving sleep quality -- has joined Apple from Philips Research.
the firm is also believed to be developing a special app called HealthBook that will be built into the next version of its iOS software, allowing users to track and analyse the data their gadget collect.
The firm's iPhone 5S already has a movement tracking chip, called the M5, which is expected to be used in the iWatch.
Reports in the New York Times claim the first-generation smartwatch will be charged wirelessly, using existing technologies currently used with select smartphones and cases.
Yet future models of the wrist-worn technology may even be powered by solar or kinetic energy to make sure they never lose charge.
Solar panels could be fitted underneath the display of the iWatch, for example, and harness the sun's energy.

Casio, for example, already uses solar technology in its G-Shock range of watches that can receive thermal and electrical energy and use it to recharge watch batteries through solar panels on the face of the watch.
This is further supported by the fact that in September, Apple posted a job vacancy looking for someone with solar expertise.
Other rumours state the watch will have a curved screen and run the next-generation of Apple software, likely to be called iOS 8.

All these current claims back up the plans laid out in an Apple patent filed in 2011.
The patent described a 'wearable accessory device' with a 'flexible display' that could use the same technology as a child's slap wrap to mount a flexible touchscreen on a user's wrist.
It also detailed a method in which the battery life could be extended, including a 'solar panel array spread across a surface of the accessory device', or 'a kinetic power source similar to those found on some wristwatches.'
