No wrist left behind: Apple iWatch will land in multiple sizes, with at least 10 different sensors

From skinny wrists to meaty forearms - the iWatch should fit them all

Apple could release more than one iWatch alongside the iPhone 6 reveal in September.

According to the Wall Street Journal's source, iWatch models with different screen sizes will be available, catering to big chunky watch lovers and minimalist fans alike.

Previous reports suggest that the iWatch could have a micro-LED display that's nine times brighter than a conventional LED offering, with lower power requirements to boot. 

If true, the iWatch could stand out from the crowd by serving up the colour and resolution of an LCD smartwatch, with the battery life of an E Ink display, like the one found on the Pebble.

The Wall Street Journal's source also believes that the iPhone will also pack in more than ten different sensors, including ones which track health and fitness.

Traditional sensors like accelerometers and ambient light sensors are probably included in that count, but there could be some interesting ones in the health tracking department.

Apple has already revealed its one-stop-shop for fitness tracking stats in the form of the Health app on iOS 8, and we expect to see the iWatch arrive with a heart rate sensor, at the very least.

There's also been speculation that the iWatch will feature a UV light sensor and a pulse oximeter for measuring blood oxygen levels, although we've yet to shed any light on the authenticity of these rumours.

We expect Tim Cook to walk onto the iPhone 6 launch stage with an iWatch strapped to his wrist, which is when all will finally be revealed. September can't come soon enough...
