The pictures suggested that the Altius runs a modified version of the Google Android operating system.
The provenance of the images is unclear and, though some websites have identified details that suggest they are genuine, it's entirely possible that they are mock-ups
for an abandoned project or even fakes made by a fan, the paper said.
The images have emerged a week after it was reported that Apple is about to launch a smart watch.
The product, which has been referred to as the ' iWatch', is apparently being worked on by a team of 100 engineers, suggesting that it is more than an experiment.
