Apple iWatch 'at least three years away', says supplier

London: Apple's much-awaited gadget, iWatch, which would be a wearable version of the iPhone , is at least three years away, one of the suppliers of the tech giant has said.

The makers of Willow glass, a flexible material expected to be used in the Apple iWatch, said that their product is not ready for use in such a complex design.

Apple supplier Corning, developer of the glass, which can be made in a roll similar to newsprint, said the technology should be in use on simple products within a year, but not for anything as complicated as a wearable smartphone, the Telegraph reports.
